Problems solved by technology

When the engine oil pump of this structure is stopped, the lubricating oil flows out of the engine parts. If it is not used for a long time, the engine parts will become dry, and the friction coefficient will increase when it is restarted, which will increase the mechanical wear and affect the performance and life of the engine. its scope of application

Abstract

The invention discloses an oil pump of an automobile engine. The oil pump comprises a pump body, a pump shaft, an outer rotor, an inner rotor and a pump cover, wherein an oil inlet cavity and an oil outlet cavity are formed in the two ends of the pump cover respectively, the oil inlet cavity communicates with the pump body, a circular arc-shaped third pipeline is in through connection with the upper portion of the oil outlet cavity, one side of the third pipeline is fixedly connected with a second pipeline, the third pipeline communicates with the second pipeline through a second through hole,the other side of the second pipeline is connected with an accommodating cylinder through a first pipeline, the accommodating cylinder communicates with the first pipeline through a first through hole, a second piston is connected with the interior of the accommodating cylinder, a third spring is connected to the lower portion of the second piston, the interior of the second pipeline is fixedly connected with a first insertion rod through a first support, a first piston movably sleeves on the first insertion rod, and a second spring is connected to the lower portion of the first piston and the first support. The oil pump has the advantages that defects in the prior art can be overcome, wear of parts of the engine can be better prevented from being increased.

Description

technical field [0001] The invention relates to an automobile component, in particular to an automobile engine oil pump. Background technique [0002] Automobile engine oil pump The pump is a kind of machine that conveys oil or pressurizes oil. It is an important part in the engine lubrication system. It mainly includes a pump body, a gear set, and a pump shaft. The gear set is installed on the pump shaft, and the pump The shaft is passed through the pump body. Chinese utility model patent CN 204629055 U discloses a wear-resistant automobile engine oil pump. When the engine oil pump of this structure is stopped, the lubricating oil flows out of the engine parts. If it is not used for a long time, the engine parts will become dry, and the friction coefficient will increase when it is restarted, which will increase the mechanical wear and affect the performance and life of the engine. its scope of application. Contents of the invention [0003] The technical problem to be ...
