An inflation valve intended to be installed in a wheel rim orifice of a vehicle, the valve being of the elastic deformation type having a valve body made of an elastomer material and a hollow rigid tube. The inflation valve includes a device able to be fixed on the hollow rigid tube and having a portion allowing a rotational movement of the valve in a first rotational direction when the inflation valve is mounted in a hole of the rim, and a portion preventing the rotational movement of the valve in a second rotational direction opposite the first rotational direction, the resulting device acting to limit an elastic deformation of the valve.

A pneumatic valve for attachment to a source of high pressure gas comprises a valve body which comprises a gas inlet and a gas outlet. A rupturable membrane extends across the gas inlet. A membrane support element is slidably supported in the valve body for movement between an extended position and a retracted position, the membrane support element having a lower end engageable, in the extended position, with the rupturable membrane to support the rupturable membrane against rupture. The valve body further comprises a bore through which the membrane support element extends and one or more gas supply passages bypassing the bore for providing a gas flow path from the gas inlet to the gas outlet. The membrane support element is configured to be movable from the extended position to the retracted position to permit the rupturable membrane to rupture under the pressure of the high pressure gas.

The present invention provides a pneumatic valve system for easily attaching and sealing a valve coupler to a valve stem for filling an inflatable vessel such as a tire, tube, mattress, etc. The valve system may comprise the following major components: a valve stem, a valve cap with a pin passage and attachment structure for attaching to a valve coupler, a sealing member, a biasing member, the valve coupler comprising a coupler housing, a pin seat, an inflation pin, and a collar with ball bearings complementary to the attachment structure of the valve cap, and an elastic sleeve for providing inward force against the ball bearings. The valve system may allow for easy, secure, and sealed engagement between the valve coupler and valve stem by simply pushing down on the valve coupler, and disengagement by pulling up on the valve coupler with as little as two fingers.

A valve stem having a hollow tube and a compression sleeve mounted to the hollow tube; wherein the hollow tube and compression sleeve are partially insertable through a container wall opening from an exterior side of the container wall through to an interior side of the container wall, and a mechanism accessible from the exterior side of the container wall to compress the compression sleeve against the interior side of the container wall.

A valve stem structure disposed at a rim of a tire of a vehicle for connecting to an electronic tire pressure monitoring device in the tire is provided. The valve stem structure includes a tube, an air core, and a conducting wire. The tube has a first inlet, a first outlet communicating with an inner space of the tire, and a second outlet. The air core is switchably disposed at the first inlet, and a compressed air is injected into the tire via the first inlet and the first outlet by switching the air core. The conducting wire is disposed in the tube, and an end of the conducting wire extends out of the tube via the second outlet to be electrically connected to the electronic tire pressure monitoring device. A power source charges the electronic tire pressure monitoring device via the conducting wire.

A self inflating float assembly includes a tube that is comprised of a resiliently expandable material. The tube has an air port extending into an interior of the tube thereby facilitating the tube to self inflate. Additionally, the tube is comprised of a fluid impermeable thereby facilitating the tube to float when the tube is inflated for performing as a personal floatation device. A valve is rotatably coupled to the air port. The valve is positionable in an open condition thereby facilitating air to pass through the air port for inflating or deflating the tube. The valve is positionable in a closed condition thereby inhibiting air from passing through the air port for retaining the tube at a selected degree of inflation.

A bobbin assembly for an automatic inflator including a generally cylindrical wall, a plurality of arms positioned in a ring centered about and parallel to a longitudinal axis of the bobbin, each arm being pivotably connected to a rim of the cylindrical wall by a living hinge, at least one of the arms including a radial seat extending toward the longitudinal axis of the bobbin to form an annular seat having a diameter to retain a head of a spring-loaded actuator pin of the automatic inflator to hold the spring-loaded actuator pin in a “cocked” position, a toroidal pill positioned between a lumen of the cylindrical wall and the ringed arms to retain the arms in position centered about and parallel to the longitudinal axis of the bobbin such that the annular seat maintains the diameter to retain the head of the spring-loaded actuator pin, thereby holding the spring-loaded actuator pin in the “cocked” position and a web interconnecting at least one of adjacent pairs of the arms allowing the paired arms to pivot outwardly via their respective living hinges in unison.

A custom valve stem is adapted to fit in a conventional valve stem opening in a tire rim. The valve stem has a primary air channel for a conventional Schrader-type valve. The valve stem also has a secondary air channel extending within the valve stem between a base of the valve stem and an outlet through the material of the valve stem to atmosphere outside of the valve stem. The outlet can have a screen as a debris air filter. An optional tire pressure monitoring system TPMS sensor couples to the primary air channel independent of the secondary air channel. The secondary air channel comprises an atmospheric hose coupled to an electric air compressor and rechargeable battery disposed within a pressure cavity of the tire for maintaining tire pressure. A motion activated power generator disposed within the pressure cavity recharges the rechargeable electric storage.

The tube has an air port extending into an interior of the tube thereby facilitating the tube to self inflate. Additionally, the tube is comprised of a fluid impermeable thereby facilitating the tube to float when the tube is inflated for performing as a personal floatation device. A valve is rotatably coupled to the air port. The valve is positionable in an open condition thereby facilitating air to pass through the air port for inflating or deflating the tube. The valve is positionable in a closed condition thereby inhibiting air from passing through the air port for retaining the tube at a selected degree of inflation.

A wheel pressure adjustment assembly includes a valve unit that is fluidly coupled to a vehicle wheel. The valve unit is actuatable in an open condition for passing air therethrough to deflate the vehicle wheel. The valve unit is actuatable in a closed condition for inhibiting air from passing therethrough to retain air pressure in the vehicle wheel at a selected pressure. The valve unit is actuatable into an inflating condition for passing air into the vehicle wheel. A compressor is coupled to the valve unit and the compressor is turned on when the valve unit is actuated into the inflating condition. In this way the compressor inflates the vehicle wheel.
