摘要： An electropneumatic valve unit (100, 200) for a vehicle brake system has a plurality of valve sections (102; 104; 106; 108; 204; 206) integrated into a single valve housing (101). The plurality of valve sections (102; 104; 106; 108; 204; 206) includes a front axle redundancy section (102) configured to provide a redundant supply or control pressure for controlling brakes associated with a front axle of a vehicle or a tractor, and a trailer control section (104; 204) for providing supply and/or control pressure to a trailer connected to the tractor. The redundant supply or control pressure for controlling brakes associated with the front axle of the vehicle at the front axle redundancy section (102) is derived from an output pressure of the trailer control section (104; 204).

摘要： One or more techniques and systems are described herein for synchronized air delivery method between a vehicle's central tire inflation system (CTIS) and an air trailer brake (ATB) system. A synchronized air delivery system can utilize a shared air source as a common shared input to drive two different systems, including the ATB system and CTIS. Based on ATB and CTIS air need feedback, an air compressor clutch can automatically control ON and OFF modes for air inputs using a control algorithm. Air can be provided to the ATB system, to provide air to brakes on a coupled trailer, over the tire inflation operation, such as during a braking event.

摘要： A control valve includes a diaphragm with a flow path with a predetermined cross-section from a brake pipe to a first side of the diaphragm and another flow path having another predetermined cross-section from a second side of the diaphragm to atmosphere. A dump valve prevents flow from the brake pipe to atmosphere. A method for operating a control valve includes supplying brake pipe air to a first side of a diaphragm through a flow path having a predetermined cross-section and permitting or preventing reference air flow to atmosphere through another flow path having another predetermined cross-section. The method further includes supplying reference air to a dump valve that prevents brake pipe air flow to atmosphere.

摘要： A valve assembly including a housing and a first movable member which divides the housing into a control chamber and a main chamber. A second movable member has a first valve part and a second valve part and is movable to engage the first valve part with a corresponding inlet valve part to substantially prevent flow of fluid into the main chamber via an inlet port. The first movable member is provided with an exhaust valve part and is movable to engage the second valve part of the second movable member to substantially prevent flow of pressurized fluid out of the main chamber via an exhaust port. A support part is secured relative to the housing, there being a first seal between the second movable member and the support part and a second seal between the support part and the first movable member.
