Abstract: The present invention relates to a pedal assembly or pedal system, comprising one or more pedals (1) whose neutral position can be adjusted. When the pedal lever acts by way of an actuating rod (7) of a control element (6) that is firmly linked with the vehicle, the readjustment of the neutral position of the pedal lever (12) simultaneously effects a readjustment of the actuator (actuating rod (7) itself. The adjustment of the neutral position of the pedal thus results in an actuation of the control element, which is not desired. An object of the present invention is to provide a pedal system such that the readjustment of the neutral position of the pedal(s) does not cause an actuation of the actuator.

Abstract: The present invention relates to a vacuum brake force booster which includes a valve piston with a pedal push rod that is axially slidable in a vacuum housing, further including a control housing and a poppet valve connected to the valve piston, and an air filter. The air filter is arranged in the valve piston and forms, in conjunction with an associated valve piston sealing seat for the air filter abuttable thereon, a variable flow cross-section for the outside air that flows through the poppet valve.

Abstract: The present invention relates to a brake force booster with a panic braking function for automotive vehicles. The present invention includes that the first sealing seat arranged movably in relation to the control housing wherein the sealing seat is fixed to a lever such that when a predetermined relative displacement between valve piston and control housing is exceeded so that the lever prevents at least a movement of the sealing seat in the actuating direction. The brake force booster with a brake assist function is easy to manufacture and, in addition, ensures a controllability of the brake force in the emergency braking position.

Abstract: The present invention relates to a brake-power transmission device, especially for motor vehicles, including an actuated input member, an output member to exert a boosting force, especially on a main brake cylinder, and a control valve arranged in a control housing to regulate the boosting force. An axially movable pressure piece is provided in the area of a reaction member. The pressure piece is supported on the input member or the control housing, thereby permitting changes to be made in the power transmission ratio. There is a general need to provide a brake-power transmission device that enables increased boosting only when required and that allows for mechanical sensing of the brake actuation speed so that immediate maximum boost force can be exerted when required without any time delay.

Abstract: The brake force booster 1 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.
