Utility model content
The purpose of this utility model is to improve traditional actuator in structure, improves actuator and installed on internal combustion engine
Security, and the structure is readily disassembled and repaired.
The technical solution adopted in the utility model is as follows：
A kind of actuator of engine valve transmission mechanism, including the porose actuator shell that can be installed on internal combustion engine
Body, axial stop is installed in the hole, being provided with described axial stop can the reciprocating liquid for driving valve
Press piston；The direction stretched out along hydraulic piston, the piston head of the hydraulic piston are located at setting for one end on the inside of axial stop
There is a circle circular bead surface；And circlip I is set on described circular bead surface, and it is provided with circlip in the end of the axial stop
II；Described piston head passes through circlip I, II.
Further, piston is limited in dismounting stroke by described circlip II.
Further, piston is limited in installation stroke by described circlip I.
Further, the internal face in the end of described axial stop is provided with the groove of a ring-type, described elasticity
Back-up ring II is installed in the groove.
Further, described circlip II diameter is more than circlip I diameter.
Further, external diameter of the external diameter of the circlip I slightly larger than circle circular bead surface.
The beneficial effects of the utility model are as follows：
It is of the present utility model that traditional actuator is improved in structure, improve the safety that actuator is installed on internal combustion engine
Property, and the structure is readily disassembled and repaired.There is circular bead surface on piston head, piston is limited in installation row by circlip I before installation
Journey, circlip I moves down into that maximum travel position is ineffective, and circlip II will live under the promotion of hydraulic piston after installation
Plug is limited in dismounting stroke.
