Problems solved by technology

However, the compression effect of the ring groove and the sealing ring is poor
[0003] In order to overcome the defect of poor pressing effect, some injectors use the tightening force of the nut to make the injector and the injector bushing tightly pressed.
After the engine runs for a long time, the nut will loosen and affect the compression effect.

Abstract

The invention relates to an oil sprayer with a pressing device. The oil sprayer comprises an oil sprayer body, an oil sprayer bushing and the pressing device. The half-ring-shaped pressing device tightly presses the bushing on the oil sprayer body through a clamping plate and comprises a clamping part, a supporting part and a pressing part, wherein the clamping part is connected with the supporting part and the pressing part sequentially. The clamping part is clamped on the clamping plate, the supporting part is pressed on the outer side of the clamping plate, and the pressing part is buckled on the oil sprayer bushing. Preferentially, the clamping part, the supporting part and the pressing part form an integrated structure, and the pressing device is made of elastic materials. The pressing device tightly presses the oil sprayer bushing through the clamping plate so that the oil sprayer has a good pressing effect and cannot be affected by engine operation.

Description

technical field [0001] The invention relates to an engine fuel injector, in particular to a fuel injector with a pressing device. Background technique [0002] The fuel injector bushing and the cylinder head body are assembled together, and a ring groove is often set on the cylinder head body. The ring groove corresponds to the fuel injector bushing, and the sealing cylinder head body and the fuel injector bushing are installed on the ring groove. ring seal ring. However, the compression effect of the ring groove and the sealing ring is poor. [0003] In order to overcome the defect of poor pressing effect, some fuel injectors use the tightening force of the nut to make the fuel injector and the fuel injector bushing tightly pressed. After the engine has been running for a long time, the nut will loosen and affect the compression effect. Contents of the invention [0004] The object of the present invention is to provide a fuel injector with a pressing device to address...
