Abstract
A multiple circuit master cylinder comprising a plurality of master cylinders arranged in tandem with the pressure in each individual master cylinder being hydraulically controlled independently of the pressure in the other master cylinders. The master cylinder piston of each master cylinder has an extension thereon which is guided in a sealed manner through a transverse housing wall to be close to the piston of the adjacent master cylinder such that should the hydraulic energy fail, all master cylinders are mechanically operated by the brake pedal.
Claims13
A hydraulic brake actuation device for motor vehicles equipped with an antiskid system comprising at least:
- a continuous-delivery pressure medium source;
- a pressure medium circuit controllably connected to said source by a pedal-operated control device;
- a first master cylinder connected to a first brake circuit and said pressure medium circuit by a first antiskid valve arrangement, said first brake circuit being independent of said pressure medium circuit, a first master cylinder piston disposed in said first master cylinder being operable by at least one of the pressure in said pressure medium circuit and a brake pedal;
- and
- a second master cylinder connected to said first master cylinder, said second master being connected to a second brake circuit and said pressure medium circuit by a second antiskid valve arrangement, said second brake circuit being independent of said pressure medium circuit, a second master cylinder piston disposed in said second master cylinder, being operable by the pressure in said pressure medium circuit and, in case of disturbances in said pressure medium circuit, by the pressure in said first brake circuit by way of a mechanical means.
