摘要： An improved fluid flow valve (10) for a fluid flow control system. The flow valve (10) includes a flow-regulating assembly (40) having a housing (44) having a piston bore (15) within which is slideably disposed a piston-like member (42). The piston-like member (42) has a primary flow passage (52) and at least one secondary flow passage (54) formed therein. A first portion (42a) of the pistonlike member (42) is configured for mating with a seat (46) of the housing (44), and a resilient member (48) biases the piston-like member (42) away from the seat (46). When at least a predetermined fluid pressure differential exists, the first portion (42a) mates with the seat (46) and causes the at least one secondary flow passage (54) to be at least substantially closed such that fluid can substantially flow only through the primary flow passage (52).

摘要： A valve, for use with a vehicular brake system including an electronic control unit, including a valve body, a pressure regulator internal to the body, a solenoid valve internal to the body and a double-check valve internal to the body. The electronic control unit (ECU) controls the traction control valve during two modes of vehicle operation. The regulator assembly is in fluid communication with the pressurized air supply and regulates the air supplied to the brake system during one mode of operation. The solenoid valve receives pressure-regulated air from the regulator assembly and is controlled by the electronic control unit during the two modes of operation. The single double-check valve receives pressure-regulated air from the solenoid valve and receives pressurized air from the supply, such that the double-check valve allows the pressure-regulated air to flow from the solenoid valve to the brake system during the one mode of operation, and allows the pressurized air to flow from the pressurized air supply to the brake system during the other mode of operation.

摘要： The present invention relates to a vehicle wheel sensor apparatus and a method that determine if a vehicle wheel sensor is active or passive, while efficiently providing the necessary connectivity, power, and communication between the sensor and a controller, without requiring a change in controller hardware. For an active sensor, the apparatus provides power and receives speed signals, high frequency vibration or acceleration signals, or other analog signals. For a passive sensor, the apparatus receives speed signals.

摘要： A tire inflation system and wheel speed sensor system having a hollow shaft rotatable with a drive mechanism. The shaft extends into the hollow end of an axle. A angular velocity system rotates with the shaft within the hollow end of the axle. A sensor, mounted within the axle, senses the rotation of the angular velocity system. The hollow shaft is a conduit for air from an air source to at least one tire.

摘要： A tire pressure control system (10) for wheels (28) of a vehicle. The system includes an air control circuit (40) having a positive pressure air source (42), a vacuum pressure air source (44), a central control unit (46), a vehicle speed sensor (47), and a command/display console (48). The control circuit (40) includes valves (62,64,66,68,70) and a conduit assembly (74) for controlling communication of the positive and vacuum pressure air to wheel valve assemblies (14) mounted on each wheel. A vent valve (86) provides quick venting of positive air pressure in the conduit assembly (74) for effecting rapid closing of a valve device (100) in each wheel valve (14). Each wheel valve also includes a valve device (104) providing substantially unrestricted air flow from the conduit assembly (74) to the wheels when valve device (100) is open and providing restricted air flow from the wheels to the conduit assembly (74) to ensure closing of the valve device (100 ) when the conduit is vented.
