Abstract
A tandem master cylinder () with central valves has ball-shaped valve members () with leaf springs () serving as valve springs. The ball-shaped valve members () can be manufactured of a plastic material, coated with an elastomer. The size of the balls is preferably adjusted to the size of the pistons () to allow a maximum flow while ensuring at the same time that the piston walls retain a thickness. The leaf springs () have a bowl-shaped body (), which is shaped like a partial sphere. To avoid an entrapment of brake fluid or a vacuum between the balls () and the leaf springs (), respectively, a central hole () has been provided in the bowl-shaped body (). The leaf springs () are equipped with a plurality of tongue-shaped extremities () extending radially outward with end portions () bent toward the axial side on which the valve members () are located.
