Abstract

The invention discloses a variable displacement oil pump for an engine and an engine component thereof. The variable displacement oil pump includes a pump body, and the pump body is provided with an oil seal installation hole, an oil suction port and an oil outlet. Adjusting ring, the adjusting ring is set in the pump body and connected to the pump body in a swingable manner; the rotor, the rotor is installed on the crankshaft and located in the adjusting ring, and the rotor and the adjusting ring are set eccentrically; multiple blades, multiple blades along the periphery of the rotor It is arranged on the rotor at intervals and movably; the sealing structure is arranged between the pump body and the adjusting ring to divide the area between the pump body and the adjusting ring into an oil suction chamber and an oil outlet chamber, and the oil suction port and the oil suction chamber Communication, the oil outlet communicates with the oil outlet cavity; adjustment assembly, the adjustment assembly is set between the adjustment ring and the pump body to adjust the eccentricity. The variable displacement oil pump according to the embodiment of the present invention has a simple structure, integrates the function of the front oil seal support, has few parts and is easy to arrange.

Description

technical field [0001] The invention relates to the technical field of engine lubrication, in particular to a variable displacement oil pump for an engine and an engine assembly with the variable displacement oil pump. Background technique [0002] The oil pump is the main component of the engine lubrication system. In the variable displacement oil pump in the related art, the cost of the parts is too high, the pressure on the overall layout of the engine is relatively high, the manufacturing process is difficult, and there is room for improvement. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a variable displacement oil pump for an engine with simple structure, easy arrangement and easy manufacture. [0004] Another object of the present invention is to propose an engine assembly having the above-mentioned variable displa...
