As shown in fig. 1, the oil circuit block with the built-in three-way shuttle valve provided by the utility model comprises an oil circuit block 9, wherein a first oil inlet 1 and a second oil inlet 4 are respectively arranged on two sides of the oil circuit block 9. The first oil inlet 1 and the second oil inlet 4 are communicated through an oil path channel 2, the oil path channel 2 is communicated with an oil outlet 6, the oil path channel 2 is cylindrical, and the inner surface of the oil path channel is smooth. And a steel ball 3 is arranged in the oil path channel 2, the diameter of the steel ball 3 is the same as that of the inner wall of the oil path channel 2, and the diameter of the oil outlet 6 is smaller than that of the steel ball. The steel ball 3 can slide in the oil path channel 2 along the axial direction, and limit sealing elements are respectively arranged between the oil path channel 2 and the first oil inlet 1 and between the oil path channel 2 and the second oil inlet 4, so that the steel ball 3 can be limited and form a sealing structure when being respectively abutted against the first oil inlet 1 and the second oil inlet 4. The limiting sealing element between the first oil inlet 1 and the oil path channel 2 is a first plug 5, and the limiting sealing element between the second oil inlet 4 and the oil path channel 2 is a second plug 7. For convenience of installation, the diameter of one end, connected with the oil path channel 2, of the first plug 5 is smaller than that of one end, connected with the first oil inlet 1, of the first plug 5. The diameter of the end, connected with the oil passage 2, of the second plug 7 is larger than that of the end, connected with the second oil inlet 4, of the second plug 7. A sleeve 8 is arranged between the second plug 7 and the second oil inlet 4, and the sleeve 8 is cylindrical and has a funnel-shaped opening structure. The funnel-shaped opening end of the sleeve 8 is connected with the second oil inlet 4, and the other end of the sleeve is connected with the second choke plug 7. In order to increase the sealing performance of the oil path, the first plug 5, the second plug 7 and the oil path channel 2 are in interference fit.
When the oil-gas separator is assembled, the second plug 7 is firstly installed into the oil-way channel 2 from the first oil inlet 1, so that the end with the larger diameter of the second plug 7 is tightly connected with one end of the oil-way channel 2.
