An air treatment unit for a brake system of a utility vehicle includes a control valve connection for pneumatically coupling the air treatment system to at least one control valve connected upstream of a wheel brake cylinder of the brake system that is configured to alter a brake pressure in the wheel brake cylinder, a supply valve for supplying the control valve connection with a required pressure, and a control device for controlling the supply valve.

A pressure regulating valve for an air supply system of a utility vehicle includes a housing having at least one compressed air connection communicating with at least one first pressure regulating chamber. The pressure regulating chamber has a variable volume delimited by at least one wall section of the housing and a first active pneumatic surface of a pressure regulating piston. In first position of the pressure regulating piston a first regulating channel is not connected to the pressure regulating chamber, and a second position of the pressure regulating piston is connected to the pressure regulating chamber. The pressure regulating piston includes a pin which rises out of the first active pneumatic surface of the pressure regulating piston. A second active pneumatic surface is located on an end of the pin. The pin is movably guided through the wall section in a pneumatically sealed manner.

The present invention is directed to a gladhand connector having multiple ports and an integrated filter. The connector has a base that includes an air hose connector clamp on a first surface, and a first access port extending from the first surface toward a second surface, and a second access port on a bottom surface. The access ports are in fluid communication with an intermediate conduit configured to direct air received from an air hose through the housing. The connector also comprises a receptacle adjacent the first access port and in fluid communication with one of the access ports. The receptacle is configured to receive a pressure sensitive, removable and replaceable filter assembly that is configured to filter debris. The filter assembly is displaceable by air pressure of received air. The connector further comprises a mounting bracket configured to be attached to a vehicle.

An electromechanical vehicle brake for a motor vehicle is disclosed, having a housing with a piston chamber containing gas, an actuating piston for a brake lining, and an electric motor for driving the actuating piston. The actuating piston can be moved optionally between a retracted position and an extended position, wherein the actuating piston is accommodated movably in the housing, such that an end of the actuating piston directed towards the brake lining protrudes from the housing and an opposite end of the actuating piston is accommodated in the housing. At least one venting unit is accommodated in the housing in order to allow a gas exchange between the piston chamber and the environment. The venting unit comprises a gas-permeable filter element and a holding element for the filter element, and the venting unit is fixed on the housing by the holding element.

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.

A pneumatic valve (1) includes a housing (6), a supply connection (8), a working connection (10) for providing working pressure (pB), an exhaust portion (12) for discharging pressurized air, an attachment portion (74), a valve member (24) and a venting guide (4). The venting guide (4) has a venting channel (108) and complementary connection elements (76) engaging the attachment portion (74), a spout (78), and a support projection (100). The support projection (100) is positioned adjacent to a contact region (102) of the housing (6) and configured to abut the contact region (102) to block tilting of the venting guide (4) relative to the housing (6). A vehicle (300) includes a brake system (200) having the pneumatic valve (1).

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.

An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus comprises an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus further comprises a quadric surface defining an effluent flow chamber that is connected in fluid communication between the inlet port and the outlet port. The quadric surface is provided for extracting contaminants from an effluent stream as the effluent stream flows from the inlet port along the quadric surface to the outlet port.

A rail vehicle includes an electric drive including a housing and power semiconductors arranged in the housing, and a braking system configured for operation with compressed air. The housing and the braking system are interconnected such as to enable supply of compressed air from the braking system to an interior of the housing. A depressurization device is arranged between the housing and the braking system such as to enable compressed air which is supplied to the housing to be depressurized prior to being supplied to the interior of the housing.
