A master cylinder for clutch release, which contains a housing, which forms a cylindrical working cavity, in which a sealing spring-loaded main piston with compensating-relief valve is located, the working cavity is divided by main piston into compensating and the pressuring cavities, in which is located an elastic element of main piston. For increasing the operational life, reliability and service life of the cylinder the compensating-relief valve, which connects and separates pressuring and compensating cavities, is made in the form of a small piston located and sealing in the main piston, at the end part of which a metallic ball or cone-shaped rotation body is installed, which freely contacts through the spring with opening of main piston. |
