    Abstract: 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).

    Abstract: 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 (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.

    Abstract: A tire inflation method is disclosed for moving air through a fluid control circuit to at least one tire that is below a target pressure. The dynamic pressure of the moving air in the fluid control circuit is monitored. A pressure control valve in the fluid control circuit is cycled on and off to prevent the dynamic pressure from reaching a predetermined amount over the target pressure.

    Abstract: A method for control of a tire pressure management system (or central tire inflation system) is provided which enables active adaptation of control variables in the system in response to variations in air line volume. The air line volume in a conduit between an air source and a vehicle tire is determined. Subsequently, one or more values for control variables are adjusted in response to the air line volume and various parameters associated with the system are determined in response to the adjusted values of the control variables.
