Description

Technical Field

[0001] The utility model relates to an oil pump capable of automatically changing flow rate, belonging to the technical field of oil pumps. Background Art

[0002] The function of the oil pump in the lubrication system is to increase the oil to a certain pressure and then force it to the moving surfaces of various engine parts. The oil pump structure can be divided into two types: gear type and rotor type. The gear oil pump is further divided into internal gear type and external gear type. The latter is generally called a gear oil pump. In a car engine, the oil in the fuel tank is transported to the inside of the engine through the oil pump.

[0003] The existing oil pump still has some problems during use. During use, the oil output of the oil pump cannot be changed, which leads to the inability to add oil according to the required amount of oil, thereby avoiding waste of oil. At the same time, when the oil outlet pipe is connected to other pipelines for a long time, it will become loose, resulting in oil leakage. Utility Model Content

It can adjust the oil output of the oil pump, thereby avoiding waste of oil and preventing the oil outlet pipe from loosening when connected to the pipeline for a long time, so as to solve the problems raised in the above-mentioned background technology.
