Abstract
The utility model discloses an oil pumping system component, comprising a delivery valve component and a plunger component both of which are assembled and connected by snap ring into a whole. The delivery valve component comprises a delivery valve joint connected to a high pressure pipe by a screw thread, a delivery valve spring, a safety valve, a safety valve body, a delivery valve and a split washer. The plunger component comprises a plug bush, a plunger spring, a plunger, a spring seat, a spring oil pump gear and a screw. The rotation of the cam of the injection pump assembly enables the plunger component to reciprocate up and down and generates oil by coming in and going out of the oil hole (oil duct); the amount of oil supply is decided by the oil-feeding position of helical flute controlled by rack and gear; the plunger supplies oil to ball non-return valve, i.e. delivery valve component, and then through high-pressure pipe, supplies the oil to the oil sprayer for oil spraying . The position of the spring oil pump gear and the feed tank of the plunger could be adjusted at will.
