ABSTRACT:
A master cylinder for actuating a hydraulic cylinder for a hydraulic brake or clutch. The master cylinder includes a cylinder body having a cylinder bore defined therein. The cylinder bore is in communication with an oil tank by way of a supply port and a relief port formed through the wall of the cylinder bore in axially spaced relation from each other. A piston is slidably received in the cylinder bore to define a hydraulic chamber forwardly thereof and comprises a pair of forward and rear piston portions axially spaced apart from each other with an annular seal member disposed therebetween. A cup support is integrally formed with the forward piston portion forwardly thereof and has a radially outer peripheral surface facing the inner peripheral surface of the cylinder bore with an annular clearance formed therebetween. Between the cup support and the forward piston portion there is defined an annular passage in communication with a communication passage which is formed in the outer peripheral surface of the forward piston portion and communicates with the supply port. A resilient piston cup is directly carried on the forward face of the cup support for controlling communication between the relief port and the hydraulic chamber in accordance with the axial sliding movement of the piston in the cylinder bore.
