According to another embodiment of the present utility model, comprise further outside described oil outlet A and be provided with seal groove.
According to another embodiment of the present utility model, comprise described bearing hole further and be provided with bearing lubrication hole.
According to another embodiment of the present utility model, comprise peripheral uniform three the Set and Positioning blocks of described pump cover main body further.
According to another embodiment of the present utility model, comprise described rotor internal cavity upper left side further and be provided with quantity control valve guide seats, rotor internal cavity left bottom is provided with flow control valve spring base for supporting.
According to another embodiment of the present utility model, comprise further above described rotor internal cavity and be provided with flow control valve sealing surface.
The beneficial effects of the utility model are, structure is simple, and oil transportation amount is large, and working stability is reliable, and good sealing effect, lubricating efficiency is high, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is outside schematic diagram of the present utility model.
1. pump cover main body, 2. rotor internal cavities in figure, 3., 4. go out oil groove B; 5. oil outlet inclined hole B, 6., 7.; 8. bearing hole, 9. selenodont goes out oil groove, 10. oil outlet; 11. go out oil pocket A, 12. oil outlet A, 13. overvoltage protection valve openings; 14. seal grooves, 15. bearing lubrication holes, 16. Set and Positioning blocks; 17. quantity control valve guide seats, 18. flow control valve spring base for supporting, 19. flow control valve sealing surfaces.
Embodiment
As Fig. 1, shown in 2, a kind of oil pump cover, comprise pump cover main body 1 and on rotor internal cavity 2, positioning pin hole 3, positioning pin hole 3 is used for oil pump cover to be fixed in oil pump, what be connected with on the right side of rotor internal cavity 2 goes out oil groove B4, go out oil groove B4 low order end and be provided with oil outlet inclined hole B5, the convenient oil extraction of inclined hole, the oil suction chamber 6 be connected with rotor internal cavity 2 lower left corner, oil inlet hole 7 is provided with bottom oil suction chamber 6, rotor internal cavity 2 center is provided with bearing hole 8, be provided with selenodont outside bearing hole 8 and go out oil groove 9, selenodont goes out oil groove 9 one end and is provided with oil outlet 10, selenodont goes out to be provided with below oil groove 9 and independent goes out oil pocket A11, go out on the left of oil pocket A11 and be provided with oil outlet A12, the oil pocket that left and right is through, oil transportation amount is large, go out oil pocket A11 and selenodont goes out between oil groove 9 to be provided with overvoltage protection valve opening 13, be convenient to overvoltage protection valve is installed, strengthen pump housing peformance margin, seal groove 14 is provided with outside described oil outlet A12, described bearing hole 8 is provided with bearing lubrication hole 15, peripheral uniform three the Set and Positioning blocks 16 of described pump cover main body 1, described rotor internal cavity 2 upper left side is provided with quantity control valve guide seats 17, strengthen quantity control valve working stability, rotor internal cavity 2 left bottom is provided with flow control valve spring base for supporting 18, increasing runoff control valve working stability, flow control valve sealing surface 19 is provided with above described rotor internal cavity 2, strengthen the sealability of rotor internal cavity 2, prevent leakage of oil situation, improve fluid utilization ratio.
Oil pump effect is after machine oil is brought up to certain pressure, is sent on the moving surface of each part of motor forcibly, its structure many employings gear type oil pump.During engine operation, bent axle drives driving gear transmission, passive tooth crop rotation opposite spin, machine oil in oil sucting cavity just enters out oil pocket along backlash and pump wall pressure, because the machine oil in oil sucting cavity is constantly taken away, therefore produce suction in oil sucting cavity, constantly the machine oil in oil sump is sucked oil sucting cavity, and the machine oil of certain pressure is pumped into lubricating oil path simultaneously.
Oil pump cover structure after improvement is simple, and oil transportation amount is large, and working stability is reliable, and good sealing effect, lubricating efficiency is high, long service life.
