Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] Such as Figure 1 to Figure 3 As shown, the infinitely adjustable variable displacement oil pump provided by the present invention includes a body 11 and a cover and a casing cover 15 on the body 11. A slide valve 9 is slid inside the body 11, and the oil pump 18 follows the movement of the slide valve 9. Sliding to change the eccentricity, the slide valve 9 divides the inside of the body 11 left and right along the sliding direction to form the first pressure regulating chamber 3 and the second pressure regulating chamber 4, in the second pressure regulating chamber 4, the gap between the slide valve 9 and the body 11 Between compression is provided with adjusting spring 7, slide valve 9 runs through and rotates and is provided with impeller drive shaft 8, and the outer end of impeller drive shaft 8 is connected with the crankshaft of engine by drive shaft sp...
