Abstract
The brake force booster with panic brake function includes a control valve, which is arranged in a control housing and operable by way of an input member, for controlling the boosting pressure in a working chamber, the said control valve including an atmosphere sealing seat on a valve piston and a vacuum sealing seat which is arranged on a sliding sleeve that is axially slidably mounted in the control housing. In the event of a panic braking, a quick depression of the brake pedal causes advance movement of the valve piston connected to the input member in relation to the control housing and the sliding sleeve, whereby opening of the atmosphere sealing seat is initiated and a clutch device is actuated which leads to supporting the sliding sleeve in the brake actuation direction on the elastically deformable reaction member, to which latter both the mechanically generated brake force and the pneumatic boosting force is applied. The clutch device is released by withdrawal of the input member. The sliding sleeve is supported on the reaction member by way of a member, by way of which also the mechanical brake force is transmitted to the reaction member.
