Fitting pin push-in support device of power steering pinion valve

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting pin pressing and supporting device of a power steering pinion valve, in which a cylinder 12 is fixed to one side of a body 10, A piston 14 is provided inside the cylinder 12 and a taper support 16 having a tapered surface 18 formed at the front end of the piston 14 is fixedly installed, The support 16 is inserted into the oilless bush 20 inserted in the body 10 so as to be guided so as to be guided in contact with the tapered surface 16 of the tapered support 16, And the support 22 is inserted into and installed in a guide interlocked with the support guide 26 mounted on the body 10 and the spring 24 is inserted into the support 22 so that the support 22 is elastically supported, Is always in surface contact with the tapered surface (18) of the taper support (16), and the workpiece (Work seat) 50 to support the support 22.
