ABSTRACT:
A brake force amplifier for the brake system of a motor vehicle, whose control valve is activated by means of a travel-limiting flexible element.
The travel-limiting flexible element is arranged outside of the amplifier, decentralized from the control valve. This arrangement saves space, and is easily disconnected should the auxiliary force fail. This is accomplished by engaging an hydraulic circuit, which is intended to transfer the motion of the travel limiting flexible element, with the assistance of a disengagement device. The disengagement device has a piston, which is subject to spring pressure on one side and to reservoir pressure on the other side and which eliminates the effect of the travel-limiting flexible element with the aid of a piston rod.
