Abstract
A master cylinder for use on a hydraulically actuated clutch or brake system of a motor vehicle, or for the like uses. The master cylinder comprises a cylindrical housing, and a piston which is axially displaceable along the housing, a piston rod in the housing. The piston rod is connected with the piston to be movable together free of play, but they are swingable with respect to each other, whereby the piston rod may swing with respect to the piston in the housing. The connection between the piston and the piston rod comprises a generally ball shaped head on the piston rod, which is held between partial shells in the housing which are shaped to partially surround and form lock to the piston rod head. The piston has a neck with receiving grooves in it. The partial shells have projections which engage in the grooves in the neck. A tubular piston-shaft sleeve in the housing is axially shiftable in the housing and is fastened to the piston. The piston neck, the piston rod ball and the partial shells are in the tubular piston-shaft sleeve.
