Abstract
A master cylinder device for controlling the pressure of hydraulic braking fluid in two separate braking circuits of a hydraulic braking system includes a housing having two parallel and co-extensive pressure chambers each movably accommodating one master piston. A pressure element transmits the brake pedal force to one of the master pistons to pressurize the fluid present in a first pressure compartment and thus in the associated first brake circuit. A part of the thus pressurized fluid is diverted to an actuating compartment of the other pressure chamber to act on the other master piston and thus to pressurize the fluid present in the second pressure compartment and in the associated other brake circuit. When elevated pressure fails to develop in the first pressure compartment, the pressure element engages a tappet of the other master piston to mechanically displace the same in the actuating direction and thus to pressurize the fluid supplied to the other brake circuit. A brake booster may be connected to the housing of the master cylinder device and act on the pressure element to boost the actuating force acting on the pressure element.
