The present disclosure relates to a hydraulic valve block and a brake driving device including the same. A hydraulic valve block of a brake driving device in which an electronic control unit is supported by one side and a motor unit controlled by the electronic control unit is supported by the other side is provided. The hydraulic valve block includes a block body in which a valve operated by an electric signal input from the electronic control unit and controlling the flow of brake oil is installed, a block through-hole formed on the block body to support the motor unit, a vent channel formed through the block body, and a first vent hole formed at one end of the vent channel and disposed above the center of the block through-hole on the other side of the block body by which the motor unit is supported.

A filter device collects and stores brake particles generated by a friction brake. The filter device can be regenerated. The filter device determines that at least one boundary condition that makes it possible and/or permits the execution of regeneration of the filter device is met. In response to the determination, brake particles stored in the filter device are to be removed from the filter device.

System for suctioning braking particles from a friction braking system of a vehicle, the suction system including a negative-pressure source, a suction mouth, a filter, a conduit connecting the suction mouth to the negative-pressure source, a control unit configured to control the negative-pressure source, the suction system further including a stream of information originating from a computer that controls a motor-generator of a driving/braking system of the vehicle, the control unit being configured to control the negative-pressure source preemptively before the actual activation of the friction braking, the control unit controlling the negative-pressure source as a function of the activation of electromagnetic braking or other parameters, and associated method.

The invention relates to a compressed-air module system for a utility vehicle, comprising a plurality of compressed-air components (46-58) and a mounting device (26) which can be attached to a vehicle frame (10) of the utility vehicle. The mounting device (26) and at least some of the plurality of compressed-air components (46-58) can be combined into a first compressed-air module (24A), wherein the first compressed-air module (24A) comprises an air compressor (56). The mounting device (26) and at least some of the plurality of compressed-air components (46-58) can be combined into a second compressed-air module (24B), wherein the second compressed-air module (24B) comprises, in place of the air compressor (56), at least one compressed air reservoir (58) from the plurality of compressed-air components (46-58).

A separating device that receives via a lower inlet an air flow laden with impurities, namely dust produced by pads of a brake assembly, and makes it possible to separate and collect heavy dust. The housing of the device contains a multi-cyclone cluster, with cyclones distributed annularly and supplied tangentially by a central collector surmounting an axial duct communicating with the inlet. The centrifuged and separated liquid and solid particles are directly collected below the cyclones in a trapping zone around the duct, the cluster forming a transverse barrier connected in a sealed manner to the duct so as to prevent the liquid collected in the trapping zone from rising towards a downstream zone, only gravity discharge orifices of the cyclones allowing the trapping zone to be filled during the operation of the device.

The present invention provides a device for controlling the exhaust of a vehicle's pneumatic system, herein after referred to as the exhaust controller. The exhaust controller may comprise at least one intake opening operable to receive compressed exhaust air via a pneumatic line and direct it towards at least one exhaust opening operable to redirect and effectively neutralize the force of the exiting air such that prevents the formation of a dust cloud. The intake opening may further comprise an adjustable connector operable to interface with a pneumatic line and create an adjustable seal with the intake opening and the pneumatic line. The pneumatic line may be an exhaust valve of the pneumatic system or airline tubing in fluid communication with the exhaust valve. The exhaust valve may be part of an air compressor, air reservoir, air brake, or an air suspension system.

A sealing assembly for installation on a port of a spring brake actuator includes a plug, a one-way valve and a cap. The plug receives the one-way valve for providing one-way air flow through the orifices and maintaining about two psi in the spring brake chamber at zero stroke. An elastomeric piece is affixed to a first set of segments of the plug for sealing against an inner surface of the port. The cap has arms sized to extend around a third set of segments of the plug and snap onto the plug. A fourth set of segments of the plug elastically deform so the sealing assembly can be installed and removed from the port easily.

The present disclosure provides a compressed air processing system of which the operation of supplying compressed air and the regeneration operation can be efficiently controlled by an electronic control unit. In particular, the present disclosure is characterized in that the pressure of a regeneration sequence valve installed in a regeneration line is increased over a set pressure by controlling a valve, which is electronically controlled, to switch, so the opening time of the regeneration line is delayed in comparison to the opening time of an unloader valve, whereby regeneration efficiency is improved.

A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

The invention relates to an electropneumatic brake system (1) for a commercial vehicle. The brake system (1) comprises brake control modules (8) by which it is possible to generate a brake pressure for service brake cylinders (6) which can be associated with single vehicle wheels or vehicle wheels of a vehicle axle. According to the invention there is a redundant compressed air supply of the brake control modules (8) by connecting the brake control modules (8) both to a compressed air reservoir (41, 42) as well as to a backup compressed air reservoir (43).
