A modulator (30) comprising an inlet (31), an exhaust (33) and an outlet (32), the modulator (30) comprising a piston (34) moveable in response to a control pressure in a control chamber (35) to vary to supply of fluid under pressure to the outlet (32), wh...

Method for controlling the inlet pressure (P26) of an ABS-control valve (13, 14) in a pressurized vehicle braking unit including at least one antiblocking system (ABS), where the ABS has at least one control unit (3), where a pressure control signal is sen...

The method involves holding the vehicle stationary using the working brake system without the driver operating the brake pedal by automatically controlling a hill holder pressure in the wheel brakes on a flat or inclined road. The hill holder pressure is a...

The application solenoid valve (16) is connected with pilot solenoid valve (12) so that operation of valve (16) is stopped by a brake cylinder based on control signals. The release pilot solenoid valve (14) and release solenoid valve (18) are connected wit...

The electromagnetic disc brake for a motor vehicle has at least one electropneumatic modulator (17) with a brake regulator (30) connectable to first and second brake circuits (3,4). The regulator controls air distribution to the brakes on an axle. The regu...

The method involves first producing the armature in its fixed form including the area for at least one elastomer element, coating the armature with a plastic coating over its entire surface, applying the uncured elastomer in the area for the elastomer seal...

The valve arrangement has a housing (2) with a connection (3) for delivering compressed air, a connection for a line leading to a load and electrically driven magnetic inlet (6) and outlet (8) valves. Further inlet and/or outlet valves can be fitted to the...

Pilot unit (1) for a brake pressure modulator comprises a first pneumatic inlet (4) connected to a pressure supply and a second pneumatic inlet (5) connected to the outlet (18) of a valve arrangement which supplies a redundant pressure. In normal operation...

The system has at least first and second brake circuits. The first circuit has at least one brake cylinder (48) for connection to a pressurized medium source for this circuit depending on a control signal from a multi-circuit braking value generator (18). ...
