Abstract

The invention discloses a single-cylinder diesel engine oil delivery pump. The single-cylinder diesel engine oil delivery pump comprises a pump body, a transmission shaft and a rotor assembly, wherein the pump body is provided with a certain inner space; a shaft hole and a rotor groove which are communicated with each other are formed in the pump body; the transmission shaft is arranged in the shaft hole; the rotor assembly is arranged in the rotor groove; the rotor assembly is sleeved on the transmission shaft and comprises an inner rotor and an outer rotor; the inner rotor and the outer rotor are successively sleeved on the transmission shaft from inside to outside; the inner rotor is optionally connected with the transmission shaft via a dismountable transmission pin; the inner rotor rotates along rotation of the transmission shaft; the outer rotor is subjected to eccentric motion along the inner rotor. The single-cylinder diesel engine oil delivery pump has the beneficial effects that the parts, the processes and the structure complexity are reduced under the condition that the same requirement is met, the processing cost and the assembling cost are reduced, the occurrence rate of liquid leakage is reduced, and the oil pumping efficiency and the assembling efficiency are improved.

Description

technical field [0001] The invention relates to an oil delivery pump, in particular to a single-cylinder diesel engine oil delivery pump. Background technique [0002] With the implementation of single-cylinder diesel engine emission regulations, the original single-cylinder diesel engine emissions cannot meet the requirements of current emission regulations, and it is necessary to innovate and improve the structure of single-cylinder diesel engines to meet the requirements of emission regulations. Among them, the fuel system of the single-cylinder diesel engine is an important part of improvement. The single-cylinder diesel engine fuel delivery pump is an important part of the single-cylinder diesel engine fuel system. The single-cylinder diesel engine has stable performance and low emission. [0003] The current single-cylinder diesel fuel delivery pump has the following disadvantages: [0004] 1. High cost and low pump efficiency; [0005] 2. Easy to leak; [0006] 3...
