With functional insert comprising a press-drawing process is a sheet metal, plastic primary piston for transmembrane tandem master cylinder and the master cylinder with such a piston

摘要

As for this invention, in regard to the primary piston (20) which is installed in the master cylinder, as for the master cylinder, in that boa also both parties at least one which is installed primary piston and the secondary piston are included. It is possible to form pressure with these pistons. The primary piston (20) has the computer (21) which consists of the formation plastic material, we have the functional insertion (22) of the metal make, this insertion, the push rod has the sphere cap form (30) which is made storage possible.
