Abstract: An air supply control arrangement for a heavy-duty vehicle including a lift axle which includes a brake chamber. The air supply control arrangement includes a valve configured to be arranged in an air supply passage that enables pressurized air to be supplied from a pressurized air source to a brake chamber of a lift axle of a heavy-duty vehicle; a processing circuitry configured to receive measurement values of the pressure inside a tire of the lift axle, wherein the processing circuitry is configured to, based on the received measurement values, determine whether the lift axle is in its raised lift condition or in its lowered ride condition, wherein the processing circuitry is configured to control the valve to move to a closed state upon determination that the lift axle has been raised from its ride condition to its lift condition, thereby preventing pressurized air from reaching the brake chamber.

Abstract: A valve assembly for use in a tire inflation system, the valve assembly including: a valve body including a first fluid port and a second fluid port; a piston disposed at least partially within the valve body and configured to be moved relative to the valve body between an open position and a closed position. When the piston is in the open position, the first fluid port is fluidly connected with the second fluid port. When the piston is in the closed position, the first fluid port is fluidly isolated from the second fluid port. When the piston is in the open position, the first fluid port and the second fluid port are fluidly connected with one another via a fluid channel extending through the piston. A tire inflation system including the valve assembly.

Abstract: A chassis mounted energy extraction and delivery system. In one embodiment, a gravity-referenced, external tire inflation facility is integrated into an aerodynamic fairing mounted on the chassis of a vehicle. In one other embodiment, a torsion bar coupled between a hub-mounted energy extraction or delivery facility and a selected portion of the chassis provides a cross-referenced fixed point of reference. In a dual-axle embodiment, a first end of the torsion bar is coupled to the hub of one axle and a second end of the torsion bar is coupled to the hub of the other axle. In a single-axle embodiment, the second end of the torsion bar is coupled to the chassis.

Abstract: A double-use nozzle adapter includes a main body, a switch unit, and a needle unit. The switch unit includes a shifting member and two rigid retaining members. The rigid retaining members are arranged between the shifting member and the main body. The shifting member shifts the rigid retaining member between a first position and a second position. The needle unit is slidably installed in the main body and includes a needle. In the first position, the shifting member drives the rigid retaining member to press against the needle, thereby preventing the needle from moving with respect to the main body and making the needle connectable to a Schrader valve. In the second position, the rigid retaining member moves between the shifting member and the main body, so as to allow the needle to move with respect to the main body and make the needle connectable to a Presta valve.

Abstract: An air delivery system is operable to on-board compressed air to an associated work vehicle from an associated or auxiliary source such as for example an external large compressor or air storage tank for assisting a tire inflation system (TIS) of the associated work vehicle to expedite tire inflation particularly when transitioning to a desired raised tire pressure, and is further operable to off-board compressed air from a compressor of the TIS system on-board the associated work vehicle for delivery from the TIS to an associated or external compressed air consuming device such as an implement attached with the associated work vehicle or the like. A bi-directional air delivery retrofit kit provides on-boarding and off-boarding of an extra-vehicular compressed air product relative to an associated work vehicle. A dual source air delivery system provides pressurized air to an air storage device from on-board and off-board pressurized air sources.

Abstract: A valve assembly for a tire pressure control system used to control tire pressure of a vehicle has a unitary body and one or more valves. The unitary body has attachment points for mounting the unitary body to a vehicle wheel end, one or more valve cavities formed in the unitary body, and a plurality of air passages formed in the unitary body. The plurality of air passages have an air supply passage that is connectable to an air supply and a tire supply chamber for connecting to a tire of the vehicle. The air supply passage and the tire supply chamber are connected to each of the one or more valve cavities. Each valve has a valve element mounted to the valve cavity, an air supply chamber in communication with the air supply passage, and a tire supply chamber in communication with the tire supply passage.

Abstract: A pneumatic pressure controller includes a body, an inflation plunger, a vent and a deflation diaphragm or piston. The body defines an input chamber and an output chamber for connection of a pneumatic pressure source and pneumatic container respectively. The plunger is biased towards a closed condition wherein it inhibits fluid flow from the input chamber to the output chamber and is movable against the bias to allow such fluid flow for inflation of the pneumatic container. The diaphragm or piston is variably biased towards a closed condition wherein it closes the vent. The diaphragm or piston is configured to move away from the vent to an open condition under the influence of fluid pressure in the output chamber when the inflation plunger is in the closed condition and the variable bias is sufficiently reduced, enabling fluid from the pneumatic container to egress to the atmosphere via the vent.

Abstract: An apparatus for inflation and deflation of tires of an automobile is disclosed. The apparatus includes an air pressure source to store the air and a valve bank having a solenoid valve for each tire of the automobile to control the flow of air from the air pressure source based on a control signal received from inflation and deflation system. Further, the apparatus includes an air control unit installed on each tire to receive air from the air pressure source via the corresponding solenoid valve. The air control unit has a central pipe to receive air pressure to press a valve stem of the tire and a surrounding pipe to facilitate ingress and egress of air into the tire and out of the tire for inflation and deflation, respectively.
