The three-way ring block 10 is fixedly connected with the rotating gear 50 to form an integrated structure, so that the three-way ring block 10 can rotate along with the rotating gear 50, and oil return holes 14 communicated with the circulation holes are circumferentially arranged at positions, close to the outer edge, of the three-way ring block 10. The single-piece valve 20 is elastically sealed outside the oil return hole 14.
That is to say, the oil-gas separation structure 100 of the engine according to the embodiment of the present invention mainly includes four parts, namely, the three-way ring block 10, the single-piece valve 20, the airflow through hole 70 and the circulation hole, preferably, there are two three-way ring blocks 10, two three-way ring blocks 10 are relatively and fixedly connected to two axial end faces of the rotary gear 50, three airflow through holes 70 axially penetrating through the rotary gear 50 are circumferentially provided on the rotary gear 50, and the airflow through holes 70 are adapted to communicate the two three-way ring blocks 10.

And this engine oil-gas separation structure 100 does not have external pipeline, and simple structure satisfies six law requirements in the state, can effectively prevent that the cold district's tortuous pipeline from freezing and leading to spouting the machine oil accident to take place.
The specific working principle of the oil-gas separation structure 100 of the engine of the present invention is as follows: the oil-gas mixture enters the rotating shaft 40 and enters one of the three-way ring blocks 10 through the air flow through hole 70, oil particles collide with the wall and adhere to the wall due to factors such as flow inertia, and the adhered oil drops are quickly thrown to the outer edge of the three-way ring block 10, namely the position of the single piece valve 20, due to the rotating force generated by high-speed rotation. When the oil drops accumulate to a certain amount, the oil return hole 14 is opened under the action of the rotating force which is larger than the elastic force of the single piece valve 20, and the engine oil particles are thrown out from the oil return hole 14 and the single piece valve 20 to be separated, so that one-time separation is realized. Because the oil return hole 14 is in the open position and has a relative displacement with the position of the air flow through hole 70, the engine oil particles subjected to the action of the rotational force cannot enter into another three-way ring block 10, the mixed gas after primary separation enters into another three-way ring block 10 through the air flow through hole 70 on the rotary gear 50, secondary separation is carried out through the same principle, and finally the mixed gas enters into the rotary shaft 40 through the flow through hole on the rotary shaft 40 and finally enters into the pressure shell of the supercharger to be mixed with fresh air to participate in combustion.
According to one embodiment of the present invention, as shown in fig. 1, the rotating shaft 40 is connected to the rotating gear 50 through a partition 45, and the partition 45 extends radially inward from the inner ring of the rotating gear 50, passes through the flow hole, and is fixed to the inner wall of the inner cavity of the rotating shaft 40. That is, the partition 45 is an integral structure with the rotary gear 50 and the rotary shaft 40, the inner cavity of the rotary shaft 40 is partitioned into the first inner cavity 41 and the second inner cavity 42 by the partition 45, and the flow hole is partitioned into the first flow-through hole 43 communicating with the first inner cavity 41 and the second flow-through hole 44 communicating with the second inner cavity 42, respectively. The first lumen 41 and the second lumen 42 communicate through a flow passage formed by the first flow through hole 43, the three-way ring block 10 communicating with the first flow through hole 43, the air flow through hole 70, the three-way ring block 10 communicating with the second flow through hole 44, and the second flow through hole 44. Specifically the gas flow direction as indicated by the arrows in fig. 8.
As shown in fig. 1, in some embodiments of the present invention, the three-way ring block 10 is embedded and mounted in mounting structures 60 provided on both axial end surfaces of the rotary gear 50.
Specifically, as shown in fig. 5, the mounting structure 60 is a groove formed on the rotary gear 50 and adapted to the shape of the three-way ring block 10. The shape of the groove is matched with that of the three-way ring block 10, so that the three-way ring block 10 can be embedded, clamped and fixed in the mounting structure 60, and integrated with the rotating shaft 40 and the rotating gear 50 into a whole structure.

At least one through structure 13, preferably, three through structures 13 may be provided, the three through structures 13 may be disposed on the inner edge of the ring body 11 in one-to-one correspondence with the protrusions 12, and the end surface facing the mounting structure 60 is provided with a second through groove 130 communicated with the ring groove 110 and the first through groove 120, the ring groove 110, the first through groove 120 and the second through groove 130 are communicated with each other to form a three-way structure, and the airflow through hole 70 is communicated with the three-way structure of the two three-way ring blocks 10. The flow holes on the rotating shaft 40 are communicated with the straight-through structures 13 in a one-to-one correspondence manner, and the flow holes can be understood as being butted with the straight-through structures 13.
