MAITRE-CYLINDRE, NOTAMMENT MAITRE-CYLINDRE TANDEM COMPORTANT DES MOYENS DE LEVEE DE CLAPET AMELIORES

摘要

The invention mainly concerns a master cylinder, in particular a tandem master cylinder comprising improved valve lifter means. The inventive master cylinder comprises at least a piston (7) sealingly sliding in a chamber (3) and provided with a valve (27) pressed against a support means (35) mounted tilting in the piston (7) so as to increase valve lift, hence maximum flow rate through the cylinder, relative to its seat without increasing pedal free travel or to reduce pedal free travel without decreasing valve lift. The support means (35) is advantageously a pin. The invention is applicable to the automotive industry. The invention is mainly applicable to the brake manufacturing industry for motor vehicles and in particular for private vehicles.
