A non-return valve device has at least part of a flow channel for a fluid and a movable cord-like sealing element arranged in the flow channel. The sealing element is configured such that it can be moved at least partially between a closed position and an open position, wherein, in the open position, a fluid flow is permitted through the flow channel, whereas in the closed position, the fluid flow through the flow channel is blocked by form-fitting engagement with the sealing element.

A bypass for an air dryer having an inlet, a prefiltration stage having a drain valve to purge contaminants, a pair of inlet valves in communication with the prefiltration stage to control the flow of compressed air through the desiccant towers, and an outlet coupled to the pair of desiccant towers. The bypass may be a bypass valve that is normally open to the outlet when the air dryer is unpowered and pilotable to be a closed to allow air to flow to the prefiltration stage when the air dryer is powered. The bypass may be a three-way valve that is normally coupled to the outlet and that may be piloted to connect to the prefiltration stage when the dryer is powered. The bypass may also be a check valve that opens in response to pressure in the inlet to allow compressed air to flow directly to the outlet.

wherein the body part is moveable in an airflow direction relative to the gasket part by bending or stretching the at least one spring part,
wherein in an unbiased basic condition of the gasket device the body part is positioned above a gasket plane defined by the gasket chamber.

The gasket device is made as a single part of a flexible, elastic material.

The present invention relates to a braking arrangement for a vehicle, the braking arrangement comprising an electric machine electrically connectable to an electric power source, a brake compressor positioned in an air flow conduit, the brake compressor being configured to pressurize a flow of air and to exhaust the pressurized flow of air, and a compressor shaft mechanically connecting the electric machine and the brake compressor to each other, wherein the electric machine is configured to generate a torque on the compressor shaft for operating the brake compressor to pressurize the flow of air, the braking arrangement further comprising an air bearing arrangement, the air bearing arrangement being fluidly connectable to a pressurized brake air tank of the vehicle via an air bearing conduit, wherein the air bearing arrangement is suspending the compressor shaft to at least one of the electric machine and the brake compressor.

An air cleaner assembly comprises a filter element and a housing assembly. The filter element comprises a filter media for filtering a fluid and a first endcap positioned along a first end of the filter media and through which a first filtered air flow portion flows. The housing assembly at least partially contains the filter element and comprises a cover that defines a first outlet through which the first filtered air flow portion flows to a downstream device. The cover comprises a noise reduction device that receives the first filtered air flow portion and dissipates sound waves traveling upstream from the downstream device.

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 device (1) has at least one venting path (10) for venting the pneumatic device (1) in an outflow direction (R1). The venting path (10) includes a first volume (12), through which a flow can pass, a first compressed-air passage (14), and a sealing mechanism (18). The first compressed-air passage (14) pneumatically connects the first volume (12) to a pressurized part (16) of the pneumatic device (1). The sealing mechanism (18) changes between a normal state (Z1) and a sealing state (Z2). In the normal state (Z1) a flow can pass through the first compressed-air passage (14) both in the outflow direction (R1) and in an oppositely directed inflow direction (R2). In the sealing state (Z2) a flow can pass through the first compressed-air passage (14) only in the outflow direction (R1).

An engine heater system for supplying compressed air to an air brake of a vehicle. The engine heater system including a gas turbine. A compressor fluidly coupled to an air reservoir of the vehicle. The air reservoir fluidly coupled to an air brake of the vehicle. A shaft rotatably attached between the gas turbine and the compressor, and when the gas turbine rotates the shaft, the compressor provides compressed air to the air reservoir of the vehicle for operating the air brake of the vehicle.

Disclosed is a system for capturing braking particles from a friction brake system, which includes a vacuum source, a pneumatic circuit that connects the friction brake system to the vacuum source, and a filter located on the pneumatic circuit and mounted on a support.
