摘要:
A rotary air connection for an automatic tire inflation system having an air pressure source, the rotary air connection comprising a stationary portion and a rotatable portion rotatably mounted to the stationary portion, the rotary air connection having a central channel with a one-way check valve disposed in the central channel so as to allow fluid to flow from the air pressure source in one direction through the central channel but not in the opposite direction toward the air pressure source.
摘要:
A rotary air connection (10) in a central tire inflation system for supplying air to the rotating tires which includes a union (20) having a stationary part (28) having an internal shoulder (34) with a rotary seal (38) and a second rotatable part including an elongate rigid tubular member (42) coaxially extendable through and longitudinally movable in the stationary part and the rotary seal. The tubular member is sealingly connected to a hub cap (14) thereby providing a structure allowing for movement and misalignment between the movable and stationary parts for the union.
摘要:
A rotary union (300) having a housing (300), a shaft rotatably disposed within the housing (402), and a tube (504) having a first end sealingly disposed within the shaft and a second end sealingly coupled to the housing. A tire inflation system (100) comprises a rotary union (300) mounted to a vehicle fairing (600).
摘要:
A valve assembly may have an inlet configured to receive pressurized fluid, a first port, a diaphragm comprising a first side and an opposing second side, a first one-way valve disposed so as to allow fluid to flow from the inlet to the first side of the diaphragm, and a second one-way valve disposed so as to allow fluid to flow from the inlet to the first port. The first side of the diaphragm may be in fluid communication with the first port and with atmosphere, and the second side may be in fluid communication with the first one-way valve, the diaphragm sealing the first port from the first one-way valve and from atmosphere, such that when fluid pressure in the first port exceeds the fluid pressure at the first valve, the diaphragm may flex to allow fluid to flow from the first port to atmosphere.
摘要:
A tire management system for a truck or trailer comprising an axle having a first tire mounted thereto, the system comprising an air pressure supply connected to the tire so as to allow sealed communication of pressurized air between the air pressure supply and the first tire, and a first pilot-operated check valve in sealed fluid communication with the air pressure supply and with the first tire, the first pilot-operated check valve being configured to allow air to flow only from the air pressure supply to the first tire when a pilot of the first pilot check valve is not activated, and to allow air to flow between the first tire and the air pressure supply when the pilot of the first pilot-operated check valve is activated.
摘要:
A high temperature warning system for a vehicle steer axle air pressure supply, a normally-closed valve in fluid communication with pressure supply, a heat sensitive control capable of opening the normally-closed valve upon a predetermined temperature, the heat sensitive control mounted adjacent to the wheel end assembly in a heat exchange relationship therewith, and a warning system connected to the air pressure supply for actuation upon opening of the normally-closed valve.
