Novel internal buffering structure of electronic control unit pump

The invention belongs to the technical field of high pressure electronic control oil injection pump assemblies of diesel engine core parts and particularly relates to a novel internal buffering structure of an electronic control unit pump. The novel internal buffering structure comprises a pump body, wherein a control valve and a stopping block are arranged inside the pump body. The novel internal buffering structure is characterized in that a buffer block is arranged inside the stopping block; the inner wall of one side of the stopping block is provided with a spring seat; a compression spring is arranged between the buffer block and the spring seat. According to the novel internal buffering structure of the electronic control unit pump, the structure is simple and the use is convenient; the impact strength of the control valve and the stopping block is greatly reduced, the lift of the control valve is well ensured, and the service life of the electronic control unit pump is extended; the cost is low and the popularization and the application are facilitated.
