도 4는 종래의 가압식 리저버탱크가 적용된 냉각시스템을 도시한 것이다.Figure 4 shows a cooling system to which a conventional pressure reservoir tank is applied.
엔진(1)과, 엔진 냉각용 냉각수를 냉각시키기 위한 라디에이터(2)와, 냉각수의 순환을 위해 엔진(1)과 라디에이터(2)를 상호 연결하는 라디에이터 호스(3)와, 구동하여 라디에이터(2)의 냉각수 냉각효율이 향상되도록 하는 냉각팬과(4)과, 냉각수호스(5)를 통해 엔진(1)으로 부터 공급되는 가열된 냉각수를 이용하여 차내로 공급되는 공기를 가열하는 히터(6)와, 상기 냉각수호스(5)의 중간부위에 결합되는 3방 조인트(7)와, 냉각수가 엔진(1)을 순환하는 과정에서 발생하는 기포의 제거 및 라디에이터(3) 내부의 압력조정을 위해 설치되는 리저버탱크(8)와, 상기 리저버탱크(8)를 순환하도록 하는 연결호스(9)로 구성되며, 미설명된 도면부호 10은 리저버탱크(8)의 상단에 결합되어 리저버탱크(8) 내부의 압력을 조절하는 라디에이터캡 (10)이다.A radiator 2 that is driven and radiator 2 for driving the engine 1, a radiator 2 for cooling the coolant for engine cooling, and a radiator hose 3 for interconnecting the engine 1 and the radiator 2 for circulation of the coolant. Heater (6) for heating the air supplied into the vehicle using the cooling fan (4) and the heated cooling water supplied from the engine (1) through the cooling water hose (5) to improve the cooling water cooling efficiency of And, the three-way joint (7) coupled to the middle portion of the cooling water hose (5), the cooling water is installed to remove the bubbles generated in the process of circulating the engine 1 and to adjust the pressure inside the radiator (3) Comprising a reservoir tank (8) and a connection hose (9) for circulating the reservoir tank (8), reference numeral 10 which is not described is coupled to the upper end of the reservoir tank (8) inside the reservoir tank (8) The radiator cap 10 to regulate the pressure.
이와같이 구성된 종래의 냉각시스템의 동작을 설명하면 다음과 같다.The operation of the conventional cooling system configured as described above is as follows.
엔진(1)이 구동하면 워터펌프의 구동에 의해 냉각수가 엔진(1) 내부를 순환하게 되고, 엔진(1) 내부를 순환하면서 가열된 냉각수는 라디에이터 호스(3)를 통해 라디에이터(2)를 통과하면서 차가워진 후 다시 라디에이터 호스(3)를 통해 엔진(1)으로 공급되어 엔진(1)이 과열되는 것을 방지하게 된다.When the engine 1 is driven, the coolant circulates inside the engine 1 by driving the water pump, and the coolant heated while circulating inside the engine 1 passes through the radiator 2 through the radiator hose 3. While being cooled and then again supplied to the engine 1 through the radiator hose 3 to prevent the engine 1 from overheating.
그리고, 엔진(1)을 순환하는 냉각수의 일부는 냉각수호스(5)를 통해 히터(6)로 공급되어지고, 히터(6)는 뜨거운 상태의 냉각수의 일부를 이용하여 차내로 공급되는 공기의 온도가 상승되도록 하여 차내가 난방되도록 하는 것이다.A portion of the cooling water circulating in the engine 1 is supplied to the heater 6 through the cooling water hose 5, and the heater 6 is supplied with a temperature of air supplied into the vehicle by using a portion of the cooling water in the hot state. Is to be raised so that the inside of the car is heated.
리저버탱크(8)의 기능은 엔진(1)이 구동할 때 이 엔진(1)을 순환하는 냉각수가 가열되면서 발생된 기포를 제거하고, 라디에이터(2) 내부의 압력이 일정하게 유지되도록 한다.The function of the reservoir tank 8 is to remove the air bubbles generated by heating the coolant circulating the engine 1 when the engine 1 is driven, so that the pressure inside the radiator 2 is kept constant.
즉, 종래의 일반적인 가압식 리저버탱크는 도 5에 도시된 바와 같으며, 리저버탱크(8)의 상단의 병목부에는 리저버캡이 나사 결합되어 장착된다.That is, the conventional general pressure reservoir tank is as shown in Figure 5, the bottle cap of the upper end of the reservoir tank (8) is mounted by screwing the reservoir cap.
종래의 가압식 리저버탱크(8)의 병목부(8a)에는 냉각수가 외부로 배출될 수 있도록 배출통로(11)가 형성되어 있고, 리저버캡(10)이 나사결합된다. 그리고 리저버캡(10)의 저면에는 리저버탱크(8)의 병목부(8a) 내부에 끼워지는 돌출부(12)가 형성되어 있는데, 상기 돌출부(12)의 내부는 상부실(13)과 하부실(14)로 구성되어 있다. 또한 상기 돌출부(12)의 상단부에는 냉각수가 배출되는 배출공(15)이 형성되어 있고, 상기 돌출부(12)의 저면에는 냉각수상승공(16)이 형성되어 있다. 그리고 돌출부(12)의 내측으로는 스프링(17)에 의해 탄지되는 밸브(18)가 장착되는데,상기한 밸브(18)는 냉각수의 압력에 의해 가동되어 리저버탱크(8) 내의 냉각수가 외부로 방출되는 것을 조절하기 위한 것이다.The bottleneck portion 8a of the conventional pressure reservoir tank 8 has a discharge passage 11 formed to discharge the cooling water to the outside, and the reservoir cap 10 is screwed. And the bottom of the reservoir cap 10 is formed with a projection 12 fitted into the bottleneck 8a of the reservoir tank 8, the interior of the projection 12 is the upper chamber 13 and the lower chamber ( 14). In addition, a discharge hole 15 through which coolant is discharged is formed at an upper end of the protrusion 12, and a cooling water rise hole 16 is formed at a bottom of the protrusion 12. In addition, a valve 18 supported by a spring 17 is mounted inside the protrusion 12, and the valve 18 is operated by the pressure of the coolant to discharge the coolant in the reservoir tank 8 to the outside. To control what is going on.
즉 종래 가압식 리저버탱크의 압력조절장치는 리저버탱크(8) 내의 압력이 높을 경우 고압력의 냉각수가 밸브(18)를 가압하게 되고, 밸브(18)를 탄지하던 스프링(17)이 압축되면서 밸브(18)가 열리게 되었다. 이렇게 밸브(18)가 열리게 되면 냉각수상승공(16)을 통해 유입된 냉각수가 배출공(15)을 통과한 후 배출통로(11)로 배출되며, 냉각수 내에 포함되어 있던 기포가 외부로 방출되는 것이다.That is, in the pressure regulating device of the conventional pressure reservoir tank, when the pressure in the reservoir tank 8 is high, the high pressure coolant pressurizes the valve 18, and the spring 17 holding the valve 18 is compressed and the valve 18. ) Was opened. When the valve 18 is opened in this way, the cooling water introduced through the cooling water rising hole 16 passes through the discharge hole 15 and is discharged to the discharge passage 11, and bubbles contained in the cooling water are discharged to the outside. .
그러나 상기와 같은 구조는 엔진이 가동되어 냉각수의 온도가 상승하게 되면 리저버탱크의 압력이 올라가게 되고 리저버탱크 내의 기포와 함께 냉각수가 외부로 방출되는데, 그 과정이 반복되므로서 리저버탱크 내의 냉각수가 부족하게 되므로서 냉각수를 자주 보충해 주어야 하는 문제점이 있었다.However, in the structure as described above, when the temperature of the coolant increases when the engine is operated, the pressure of the reservoir tank increases and the coolant is discharged to the outside together with the bubbles in the reservoir tank. There was a problem that must be frequently replenished with the cooling water.
따라서 본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서, 보다 상세하게는 냉각수가 라디에이터를 통과하게 되면 기포가 발생되는데, 이 기포를 제거하기 위한 리저버캡이 장착되는 리저버탱크의 병목부분에 깔대기 형상의 배출보조탱크를 형성하여 리저버탱크의 압력이 높아져 외부로 넘치는 냉각수를 임시 저장하였다가 리저버탱크의 압력이 낮아지게 되면 저장되었던 냉각수가 다시 리저버탱크로 유입되도록 하는 가압식 리저버탱크의 압력조절장치를 제공하는 데 있다.Therefore, the present invention is a means for achieving the above object, more specifically, the bubble is generated when the cooling water passes through the radiator, funnel shape in the bottleneck portion of the reservoir tank is equipped with a reservoir cap for removing the bubble It provides a pressure control device for the pressurized reservoir tank to form a discharge auxiliary tank of the reservoir tank so that the pressure of the reservoir tank is increased to temporarily store excess coolant to the outside, and when the pressure of the reservoir tank is reduced, the stored coolant flows back into the reservoir tank. There is.

A cooling water hole 32 is formed at an upper end of the protrusion 31, and cooling water is provided at the bottom thereof. The rising hole 33 and the cooling water falling hole 34 are formed.
그리고 상기한 돌출부(31)의 내부 공간(35)에는 스프링(36)에 의해 탄지되는 압력밸브(37)가 수용되는데, 상기한 압력밸브(37)는 돌출부(31)의 저면에 형성된 냉각수상승공(33)을 차단하기 위한 것이다. 또한, 상기한 압력밸브(37)의 내부 공간(37a)에는 별도의 소형스프링(38)이 장착되는데, 상기한 소형스프링(38)은 돌출부(31)의 저면에 형성된 냉각수하강공(34)를 개폐하는 진공밸브(39)를 탄지하기위한 것이다. 특히 상기한 압력밸브(37)의 측면에는 리저버탱크(20) 내의 압력이 하강했을 경우 돌출부(31) 공간(35) 내의 냉각수가 압력밸브(37) 내부의 공간(37a)로 흐를 수 있도록 관통공(43)이 형성된다.In addition, a pressure valve 37 carried by the spring 36 is accommodated in the internal space 35 of the protrusion 31, and the pressure valve 37 is a cooling water rising hole formed at the bottom of the protrusion 31.

엔진이 작동하여 냉각수의 온도가 상승하게 되면 리저버탱크(20) 내의 압력이 올라가게 된다.When the engine operates to increase the temperature of the coolant, the pressure in the reservoir tank 20 increases.
리저버탱크(20) 내의 압력이 상승하게 되므로서 압력밸브(27)는 스프링(36)을 가압하며 상승하게 된다. 압력밸브(27)가 상승하게 되므로서 냉각수상승공(33)은 개방되고, 가압된 냉각수는 냉각수상승공(33)을 통해 리저버캡(30)의 공간(35)으로 상승이동하게 된다. 상기한 공간(35)로 상승된 냉각수 및 증기는 돌출부(31)의 상단에 형성된 냉각수공(32)를 통해 깔대기 모양의 배출보조탱크(23)로 흘러 넘치게 된다.As the pressure in the reservoir tank 20 rises, the pressure valve 27 presses the spring 36 and rises. As the pressure valve 27 is raised, the cooling water rising hole 33 is opened, and the pressurized cooling water is moved upwardly to the space 35 of the reservoir cap 30 through the cooling water rising hole 33. Cooling water and steam raised to the space 35 is overflowed to the funnel-shaped discharge auxiliary tank 23 through the cooling water hole 32 formed on the upper end of the projection (31).
이렇게 배출보조탱크(23)에는 냉각수가 고이게 되는데, 고이는 냉각수의 양이 많을 경우에는 깔대기 모양의 배출보조탱크(23)를 흘러 넘쳐 배출통로(21)를 통해 외부로 방출되게 된다. 이 과정에서 냉각수에 포함되어 있던 기포는 배출통로(21)를 통해 외부로 빠져 나가게 되는 것이다.Thus, the coolant is accumulated in the discharge auxiliary tank 23. When the amount of the coolant is large, the coolant flows through the discharge auxiliary tank 23 having a funnel shape and is discharged to the outside through the discharge passage 21. Bubbles contained in the cooling water in this process is to exit to the outside through the discharge passage (21).
이상과 같이 상승하였던 리저버탱크(20) 내의 압력이 하강하게 되면 압력밸브(37)는 스프링(36)의 탄력에 의해 하강하게 되는데, 이때 진공밸브(39)는 리저버탱크(20) 내의 압력저하에 의한 부압에 의해 하향으로 열리게 된다.When the pressure in the reservoir tank 20 rises as described above, the pressure valve 37 is lowered by the elasticity of the spring 36. At this time, the vacuum valve 39 is lowered in the pressure in the reservoir tank 20. It is opened downward by the negative pressure.
상기한 진공밸브(39)가 열리게 되면 배출보조탱크(23)에 저장되어 있던 냉각수는 돌출부(31)의 하부에 형성된 바이패스공(42)을 통해 공간(35)로 유입되고, 공간(35)에 유입된 냉각수는 압력밸브(37)의 측면에 형성된 관통공(43)을 통해 압력밸브(37) 내부에 형성된 공간(37a)으로 유입되고, 개방된 냉각수하강공(34)를 통해 리저버탱크(30)올 다시 유입되게 된다.When the vacuum valve 39 is opened, the coolant stored in the discharge auxiliary tank 23 flows into the space 35 through the bypass hole 42 formed in the lower portion of the protrusion 31, and the space 35. Coolant flowed into the space (37a) formed inside the pressure valve 37 through the through hole 43 formed on the side of the pressure valve 37, the reservoir tank (34) through the open cooling water drop hole (34) 30) All will be introduced again.
즉, 냉각수를 저장하는 리저버탱크(20) 내의 압력상승에 의해 외부로 방출되는 냉각수의 일부를 배출보조탱크에 일시 저장하였다가, 리저버탱크(20) 내의 압력이 하강하게 되면 저장되었던 냉각수를 다시 리저버탱크(20)로 유입시키므로서 냉각수의 방출을 방지하게 되는 것이다.That is, a part of the coolant discharged to the outside due to the pressure increase in the reservoir tank 20 storing the coolant is temporarily stored in the discharge auxiliary tank, and when the pressure in the reservoir tank 20 falls, the stored coolant is again stored. By introducing into the tank 20 is to prevent the discharge of the cooling water.
이상과 같은 본 발명은 리저버캡이 장착되는 리저버탱크의 병목부분에 깔대기 형상의 배출보조탱크를 형성하여 리저버탱크의 압력이 높아져 외부로 넘치는 냉각수를 임시 저장하였다가, 리저버탱크의 압력이 낮아지게 되면 진공밸브가 개방되어 저장되었던 냉각수가 다시 리저버탱크로 유입되므로서 리저버탱크 내의 냉각수의 방출을 방지할 수 있는 효과가 있는 것이다.The present invention as described above forms a funnel-shaped discharge auxiliary tank in the bottleneck portion of the reservoir tank equipped with the reservoir cap to increase the pressure of the reservoir tank to temporarily store the coolant overflowed to the outside, when the pressure of the reservoir tank is lowered The coolant, which has been opened and stored in the vacuum valve, flows back into the reservoir tank, thereby preventing the discharge of the coolant in the reservoir tank.
