Embodiment Construction
[0053] figure 1 It is an explosion diagram of a variable displacement rotor oil pump according to an embodiment of the present invention. like figure 1 As shown, the variable displacement rotor oil pump includes a pump casing 3 and a pump cover 7 facing the pump casing 3 , and bolts 16 are used to fixedly connect the pump casing 3 and the pump cover 7 . In an assembled state, the pump casing 3 and the pump cover 7 will define a receiving chamber between them for receiving the outer rotor 4 , the inner rotor 5 and the push plate 6 .
[0054] refer to image 3 , The pump casing 3 has a pump casing low-pressure oil zone 3.4 and a pump casing high-pressure oil zone 3.2 spaced apart. refer to Figure 5 , similarly, the pump cover 7 also has a pump cover low-pressure oil zone 7.1 and a pump cover high-pressure oil zone 7.5 spaced apart. In this way, when as Figure 12 and Figure 15 As shown, after the pump casing 3 and the pump cover 7 are assembled facing each other, in the...
