And a valve spring 144C interposed between the discharge valve 144B and the discharge cover 144A to elastically support the discharge valve 144B.
토출커버(144A)는 "캡"모양으로 형성하여 토출공간과 플랜지부를 잇는 모서리에 상기한 토출가스안내홈(144a)을 형성한다. The discharge cover 144A is formed in a "cap" shape to form the discharge gas guide groove 144a at the corner connecting the discharge space and the flange portion.
도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.
상기와 같은 본 발명 왕복동식 압축기의 맥동 및 소음 저감 장치는 다음과 같은 작용 효과를 갖는다.The pulsation and noise reduction device of the reciprocating compressor of the present invention as described above has the following effects.
즉, 왕복동식 모터(130)에 전원을 인가하면 피스톤(142)이 왕복동식 모터(130)의 가동자(133)와 함께 플럭스의 방향에 따라 움직이면서 공진스프링 유니트(150)에 의해 지속적으로 왕복운동을 하여 냉매가스를 흡입 압축하였다가 토출하는 일련의 과정을 반복한다.That is, when power is applied to the reciprocating motor 130, the piston 142 moves along the direction of the flux with the mover 133 of the reciprocating motor 130, and continuously reciprocates by the resonant spring unit 150. The process of repeating the suction gas compression and the discharge of the refrigerant gas is repeated.
이때, 토출가스는 토출밸브(144B)를 이기고 토출커버(144A)의 토출공간으로 1차 토출하였다가 다시 토출가스안내홈(144a)과 실린더(141)의 토출가스안내공(141a) 그리고 전방프레임(121)의 토출가스안내유로(121b)를 통해 공명공간덮개부재(160)에 의해 밀폐공간을 이루는 첫 번째 공명공간(S1)으로 유입한다. 이 토출가스는 다시 토출가스안내관(170) 또는 가스유통홈(180)을 통해 다음 공명공간(S2)을 연속으로 지나면서 헬름홀쯔 효과에 의해 소음이 상쇄된 후에 마지막 공명공간에서 토출관(DP)을 거쳐 케이싱(110)의 외부로 토출하는 것이다. 특히, 각 공명공간(S1)(S2)을 긴 토출가스안내관(170)으로 연결하는 경우에는 목길이가 그만큼 길어짐에 따라 소음감쇄효과를 더욱 높일 수 있다.At this time, the discharge gas is first discharged over the discharge valve 144B to the discharge space of the discharge cover 144A, and then discharge gas guide groove 144a and discharge gas guide hole 141a of the cylinder 141 and the front frame. Through the discharge gas guide passage 121b of 121, the resonance gas is introduced into the first resonance space S1 forming a closed space by the resonance space cover member 160. The discharge gas passes through the discharge gas guide tube 170 or the gas distribution groove 180 again and continuously passes through the next resonance space S2, and noise is canceled by the Helmholtz effect. Is discharged to the outside of the casing (110). In particular, when the resonance space (S1) (S2) is connected to the long discharge gas guide pipe 170, as the length of the neck is longer that can further increase the noise reduction effect.
이렇게 하여 냉매가스의 토출시 토출밸브가 실린더의 선단면에 충돌하면서 발생하는 소음 등을 효과적으로 제거함에 따라 압축기 소음을 현저하게 줄일 수 있다.In this way, the compressor noise can be remarkably reduced by effectively removing the noise generated while the discharge valve collides with the front end surface of the cylinder during discharge of the refrigerant gas.
본 발명에 의한 왕복동식 압축기의 맥동 및 소음 저감 장치는, 토출커버와 연통하는 공명공간을 전방프레임의 전방면에 형성함으로써, 토출가스가 상기한 토출커버에서 먼저 공명된 후 다시 각각의 공명공간을 순차적으로 지나면서 공명되어 압축기 소음이 현저하게 줄어드는 효과가 있다.The pulsation and noise reduction device of the reciprocating compressor according to the present invention forms a resonance space communicating with the discharge cover on the front surface of the front frame, whereby the discharge gas is first resonated in the discharge cover, and then the respective resonance spaces are again formed. There is an effect that the resonance noise is sequentially reduced and the compressor noise is significantly reduced.
