The master cylinder and the especially dual master-cylinder which have improved valve lift expedient

摘要

This invention mainly regards the dual master-cylinder which has the valve lift expedient which the master cylinder especially is improved. As for the master cylinder by this invention, the chamber (3) inside in sealing up state we have one which smooth movement the valve lift quantity for the seat possibly is installed piston (7) at least, in order in the piston (7) to shaking, the valve (27) which this touches to the support expedient (35) which is installed being installed, we play in this piston and without increasing distance, therefore, we increase the maximum stream flow which passes by the master cylinder, we play or, without reducing the valve lift quantity and decrease distance. Support expedient (35) is the pin favorably. To apply to especially automobile industry it is possible this invention. Mainly, to apply to the brakes industry which relates to the brake of the automobile and the especially private car it is possible this invention.
