Abstract
A master cylinder for a vehicle braking system. The master cylinder including a housing defining a bore therewithin with a piston slidably mounted in said bore. The piston head and the housing bore define a pressure chamber in communication with at least one brake actuator. A conventional annular ring cooperates with the wall of the housing bore and with a radial surface of the piston head for controlling fluid communication between a supply chamber of the master cylinder which communicates with a reservoir and the pressure chamber. The annular ring has a lip which projects toward the radial surface so as to form a non-return valve which prevents fluid communication from the pressure chamber toward the supply chamber when the master-cylinder piston is out of its rest position.
