Abstract: This invention provides a brake pressure control device for connection in series with the control valve of an anti-skid pneumatic braking system having an axially movable piston the position of which is determined by the difference between the pressure in a chamber communicating with the brake actuator itself and a chamber communicating with the brake pressure supply through a first floor restricting passage. The piston is normally in a closed position, but when the pressure at the brake actuator is released by the action of the anti-skid control valve upon detection of imminent wheel locking the piston moves into an operative position in which it places the said chamber in direct communication with the brake pressure supply while at the same time limiting the pressure supply to the brake control valve to a second restricted passage preventing sharp re-application of the brakes by the control valve.

Abstract: A pressure reducing valve has a plunger having an axial hole, which plunger is movable in a valve body between two extreme positions defined by stops and under the action of resilient means. A stem valve is movable in the axial hole and is adapted to assume a stop position such that it closes the axial hole when the plunger is in a rest position and that it leaves the hole open when the plunger is in the other positions. A control aperture admits a control pressure to a reaction surface on the plunger in order to produce a regulable increase in the resistance offered by the resilient means to the movement of the plunger.

Abstract: When a brake system on a commercial vehicle, lateral acceleration and/or yaw of the vehicle are monitored and compared to a first predetermined threshold. If the first predetermined threshold is exceeded, a precharge command is sent to the brake system to precharge one or more air chambers by temporarily deactivating a modulator valve and activating an antilock traction relay valve in order to charge the air chambers up to a level permitted by the modulator valve. Upon detecting a panic braking event, a command signal is sent to the brake system to release the precharged air to facilitate braking.

Abstract: A service brake device for vehicles is provided which permits rapid venting of a service brake pressure chamber. The service brake device includes at least one pneumatic service brake device with at least one piston and/or a diaphragm. The piston and/or diaphragm delimits the service brake pressure chamber on one side which can be supplied with compressed air from a brake line for applying the service brake and can be purged of compressed air for releasing the service brake, delimits a spring chamber on the other side which receives a spring that prestresses the piston and/or the diaphragm in the release position of the service brake. The pressure chamber includes a pressure connection communicating with the brake line. A quick air release valve between the brake line and the pressure chamber is arranged to connect the brake line to the pressure chamber when the pressure in the brake chamber is greater than in the pressure chamber, and to connect the pressure chamber to the spring chamber when the pressure in the pressure chamber is greater than the brake line pressure.

Abstract: An improved, air tight valve seat for a pneumatic brake system is achieved by using a plastic valve seat that is coined by the valve member. The valve member is a harder material, for example metal, than the thermo-plastic valve seat. The valve member is brought to an elevated temperature less than the melting point of the valve seat. The valve member engages the valve seat, coining the desired surface of the valve seat to conform it to the valve member. The heated valve member then remains in the valve assembly after coining.

Abstract: A relay valve has a housing in which is mounted a diaphragm piston to define on one side a valve chamber connected to the brake cylinder and on the other side a control chamber whose volume is relatively small with respect to the volume of the pressure-medium utilized by the brake cylinder. A double valve member has an outlet valve for disconnecting the valve chamber from the atmosphere through a valve seat on the diaphragm piston and has an inlet valve connected by a connecting pipe to the valve member of the outlet valve so as to close the valve chamber with respect to the chamber connected to a source of pressuremedium through a valve seat fixed in the housing. Extending from the diaphragm piston is a cylinder which traverses the control chamber and leads to the atmosphere. The inner end of the cylinder is closed on the valve chamber side by the outlet valve. The connecting pipe is guided in sealing relationship in a partial chamber which can be connected to the control chamber by a solenoid outlet valve and there is a nozzle in the connecting pipe which substantially reduces the cross-sectional flow area of the pipe.
