Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
It should be noted that, in the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Furthermore, in the present disclosure, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature. The terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1-2, the variable displacement oil pump with an integrated oil outlet slider includes a pump body 1, a pump cover (not shown in the drawing), an oil cavity disposed in the pump body 1, a slider 2 and a spring 3 disposed in the oil cavity, and a rotor 4 disposed in the slider 2, wherein the rotor 4 is provided with a shaft hole 4a for an engine crankshaft to pass through, the bottom of the oil cavity is provided with an oil inlet and an oil outlet, one side of the slider 2 is fixedly connected with a u-shaped expansion block 6, an oil outlet channel 6a for oil inside the slider 2 to enter is defined between the expansion block 6 and the outer wall of the slider 2, and the oil outlet is located at one end of the oil outlet channel 6 a.
When the variable displacement oil pump with the integrated oil outlet sliding block works, the engine crankshaft drives the rotor 4 to rotate, oil enters the oil cavity from the oil inlet, is pressed into the oil outlet channel 6a of the expansion block 6 under the driving of the rotor 4, and then is discharged from the oil outlet. The capacity expansion block 6 is arranged on one side of the sliding block 2, so that an oil outlet channel 6a is formed in the capacity expansion block 6, the position of an oil outlet can be moved to the outer side of the sliding block 2 to correspondingly communicate with the oil outlet channel 6a, mutual interference between the position of the oil outlet structure and the position of the chain structure can be avoided, the position of the chain does not need to be changed, and the compactness of the chain and the pump body is kept.
It should be understood by those skilled in the art that the inner wall surface of the oil chamber may be provided with a wall groove 5 for accommodating the capacity expansion block 6 and allowing the capacity expansion block 6 to swing therein, so that the swing action of the slider 2 during operation can be performed normally to achieve variable displacement.
In addition, in this embodiment, it is more preferable that the expansion block 6 and the slider 2 are formed integrally, so that the structural stability caused by the integral structure is better.
The above-mentioned embodiment is the utility model discloses the implementation scheme of preferred, in addition, the utility model discloses can also realize by other modes, any obvious replacement is all within the protection scope of the utility model under the prerequisite that does not deviate from this technical scheme design.
