An electropneumatic parking-brake valve unit for an electronically controlled pneumatic brake system has a first supply connection to a compressed air source. A spring brake connection connects to a spring brake cylinder of a vehicle. A parking-brake valve arrangement has a bistable valve switchable between switching states wherein a spring brake pressure can be controllable in dependence upon the switching state. A pneumatically switchable holding valve has a holding-valve connection for a first control pressure and the holding valve is connected between the first supply connection and the bistable valve. The holding valve is under a spring load into a first switching position wherein the bistable valve is connected to a deaerator. The bistable valve switches into a second switching position when the first control pressure exceeds a first threshold value. The bistable valve is connected to the first supply connection.

An oil separator includes a housing and an impingement member arranged in the housing. The oil separator introduces air containing oil into the housing and causes the air to strike the impingement member to separate the oil from the introduced air, thereby recovering the oil into a liquid storage portion. The oil separator further includes a liquid restoration device that restores collected liquid to an external device. The collected liquid contains the oil that has been separated from the air and recovered. The liquid restoration device includes an inlet port connected to the liquid storage portion, a retaining portion, and a discharge port connected to the external device.

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.

A device is provided for detachably fastening a drying agent cartridge to a housing section of a compressed-air treatment installation of a vehicle. The drying agent cartridge has a cartridge housing with a cover and a carrier element, which, in an installed position, is detachably fastened to the housing section. The device includes a thread arranged on the carrier element, and a counterpart thread arranged on the housing section, and a sealing element arranged between the carrier element and the housing section. The sealing element is arranged in a seal groove of the housing section and fluidically connects the seal groove to a pressurizable housing chamber of the compressed-air treatment installation, can be acted on with a system pressure of the compressed-air treatment installation in order to generate and/or increase the axial compression of the sealing element between the carrier element and the housing section.

An air-guiding device for cooling the brakes has adjustable air-guiding flaps and an electronic control unit for controlling the air-guiding flaps as a function of the vehicle speed and of the pilot control pressure, triggered by the activation of the brake pedal, in the brake system. A first mode and a second mode for opening the air-guiding flaps are provided in the control unit by a corresponding program module. The first mode is directed to a strong deceleration demand at a relatively high vehicle speed, in particular on freeways and country roads. The second mode is directed to an acceleration prevention demand at a relatively low vehicle speed, in particular when travelling downhill on roads through mountain passes.

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).
