A valve assembly for a tire inflation/deflation system includes a body having a control port and a tire port, and a valve member for fluidly connecting or disconnecting the control port with the tire port. In one embodiment, the valve includes a fluid-operated damper having a damper chamber for controlling a timing of the valve member. A vent valve is provided for permitting excess fluid pressure to escape from the damper chamber. In another embodiment, the valve member includes a diaphragm separating first and second fluid chambers. A vent passage and at least one resilient fluid pressure-operated valve element are provided for enabling fluid to vent from the first chamber to the second chamber. Multiple-redundant valve elements may be provided to form an isolation gap that restricts contamination of the valve assembly.

A valve comprises a base, a cover and a sealing member. The base comprises a passage structure and a retaining member; the cover comprises a corresponding retaining member and at least one hole, and the cover is movably combined with the base and switchable between a first state and a second state relative to the base; a sealing member is disposed between the passage structure and the cover. In the first state, the cover closes the passage structure by the sealing member to prevent the flow of the fluid between the cover and the base; in the second state, at least one fluid channel is formed between the cover and the passage structure and is in communication with the at least one hole, and the retaining member and the corresponding retaining member prevent the cover from being separated from the base when the cover moves relative to the base.

The present invention relates to a valve for inflatable apparatuses. The valve comprises a housing, a sealing disc and a handle. The handle is coupled to the sealing disc, and is adapted for rotating the sealing disc within the housing.

A pressure relief valve may comprise a housing, a disk, and a seal. The disk may be configured to deflect relative to the housing. The seal may form a sealing interface with at least one of the housing or disk. The pressure relief valve may be coupled to an inflatable slide or an aspirator.

A fluid controller comprising a housing separating an interior of the housing from an inflatable bladder is disclosed, the fluid controller including a plurality of valves fluidly coupling the interior of the housing to the inflatable bladder through a respective opening in the housing, a pump located at least partly within an interior of the housing, wherein the plurality of valves and respective orifices are configured to provide a fluid path between the interior of the housing and the inflatable bladder during inflation of the inflatable bladder, and wherein a valve and respective orifice is biased open to provide a fluid path between the interior of the housing and the inflatable bladder for fluid release.

A pneumatically operated gas valve includes a piston positioned in a cylinder with one closed end so that the piston may seat against a gas outlet to close the gas valve. A control reservoir may be formed in the cylinder between the piston and the closed end of the cylinder. Means for filling the control reservoir with gas to a control pressure may be provided so that the control pressure acting against the piston may close the gas valve. A release valve may be opened to allow the gas in the control reservoir to escape through an exhaust port to open the gas valve.

A tire stem torque device is provided for tightening a valve stem of a tire mounted with one or more auxiliary tires on an axle of an automobile, without dismounting one or more of the auxiliary tires from the axle. The tire stem torque device includes a head member, an elongate member attached to the head member, and a handle attached to a distal end of the elongate member. The head member is configured of multiple sizes and defines a space configured to receive a valve stem of multiple sizes. The elongate member is configured of an adjustable length to create sufficient torque for the tightening of the valve stem of the tire.
