[0048] See also Figure 3 The upper port of the exhaust outlet 4 is installed with an exhaust quick plug 12 through a quick plug screw, and the lower port of the exhaust outlet 4 is installed with an exhaust check valve 13.

[0049] See also Figure 3The upper port of the negative pressure oil inlet 5 is installed with a negative pressure quick plug 14 through a quick plug screw, and the lower port of the negative pressure oil inlet 5 is installed with a negative pressure oil one-way valve 15.

[0050] See also Figure 3 and Figure 6 The regulating oil supply port 3 is connected to the regulating channel 7, and an adjusting screw 16 is arranged inside the regulating oil supply port 3. When in use, the oil supply amount can be adjusted by adjusting the screw 16.

[0051] See also Figure 1 A sealing groove is provided on the outer periphery of the other end of the filter seat 1, and a sealing ring 17 is installed in the sealing groove.

[0052] See also Figure 6 The oil inlet channel 9 is arranged in parallel with the oil supply channel 8, and one end of the oil inlet channel 9 is connected to the inner cavity of the filter element 2.

[0053] See also Figure 6 One end of the oil supply channel 8 is connected to the adjustment channel 7, and the other end of the oil supply channel 8 is blocked by the process hole screw 18, and the side of the oil supply channel 8 is connected to the oil outlet 6.

[0054] Working principle: When the oil-gas-water separator electric pump is working, the fuel in the fuel tank enters the oil-gas-water separator, and the electric pump drives the mixed gas inside and outside the filter element of the oil-gas-water separator through the oil inlet 11, enters the oil inlet channel 9 to reach the degassing filter, and the filter element 2 is installed in the degassing filter, and the gas is isolated outside the filter element 2. The mixed oil and gas outside the filter element 2 enter the fuel tank through the exhaust outlet 4, and the gas-free fuel in the filter element 2 passes through the guide pipe 10 and enters the oil supply channel 8 to supply the gas-free fuel from the oil outlet 6 to the main oil supply channel of the oil-gas-water separator, and finally to the engine for combustion;

[0055] When the oil-gas-water separator electric pump stops working, under the action of the engine gear pump, the engine return oil enters the degassing filter through the negative pressure oil inlet 5, and the fuel in the filter element 2 passes through the guide pipe 10 and enters the oil supply channel 8 to supply the fuel from the oil outlet 6 to the main oil supply channel of the oil-gas-water separator, and finally to the engine for combustion;

[0056] In the implementation case, after the one-way valve is removed from the exhaust outlet and the negative pressure oil inlet, the two can share the same channel, and the target effect of the utility model can also be achieved;

[0057] The electric pump can realize the dual functions of long oil supply and intermittent oil supply by using the control system. The oil supply mode of the electric pump can be switched according to the cargo capacity and different road conditions to achieve the best fuel saving effect. When the electric pump is working, exhaust is carried out, and the oil-gas-water separator and the degassing filter supply oil to the main oil channel at the same time; when the electric pump stops working, the oil-gas-water separator supplies oil, and the degassing filter uses the suction force generated by the engine gear pump to make the return oil enter the degassing filter to supply oil to the main oil channel. The present invention realizes two-way oil supply, reduces the engine's oil extraction resistance, increases power, and achieves fuel saving. It does not need to rely on the engine's self-priming and rely on the electric pump for forced oil supply and exhaust during startup, prevents the gas of the mixed oil from entering the engine, reduces the carbon deposits generated inside the engine, improves its power, and avoids affecting the engine life.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
