A pneumatically operated gas valve mounted on a vessel containing pressurized gas. The gas valve includes a piston positioned in a cylinder with one closed end so that the piston seats against a gas outlet to close the gas valve. A control reservoir is formed in the cylinder between the piston and the closed end of the cylinder. Upon filling vessel, some of the pressurized gas enters the control reservoir to provide a control pressure behind the piston. Actuating the control mechanism vents the control reservoir, resulting in the gas valve opening rapidly to release the pressurized gas in the vessel through an exhaust port of the gas valve.

A push-to-press inflation adaptor is provided for use with an English valve and includes a valve connector, a connection barrel, a coupler, an air tube, and a spring. The valve connector includes a first movement hole, a positioning cavity, a communication compartment, a valve opening and a constraint opening. The connection barrel is coupled to the valve connector. The connection barrel includes a second movement hole and an air tube opening. The coupler is received in the first movement hole and the second movement hole of the valve connector and the connection barrel and is reciprocally movable through application of a force thereto. The air tube is received through the air tube opening into the connection barrel to be jointed to the coupler. The spring is supported between the coupler and the connection barrel to provide a preloading force to bias the coupler in a direction toward the constraint opening.

The present invention discloses a threaded fixing structure, comprising an inflating valve, a base and a sealing ring, the inflating valve is in threaded connection with the base, the sealing ring is arranged between the inflating valve and the base, after the threaded connection between the inflating valve and the base is completed, a fixed protrusion portion is formed on the surface, attached to the inflating valve, of the base by punching, and the fixed protrusion portion is sunken into the inflating valve to limit the relative rotation between the base and the inflating valve. According to the present invention, the inflating valve and the base are limited and locked with each other through a fixing part, so that the relative rotation between the inflating valve and the base is avoided, the threaded connection between the inflating valve and the base is prevented from loosening, and as a result, the connecting effect of the base and the inflating valve is improved.

A device for a motor vehicle tire including an inflation valve comprising an elastomer body (2) having an internal shoulder (6) coming to bear in the tire on a rim edge, and including an electronic module of a system for monitoring pressure inside the tire that is disposed in a housing (12) made of two half-shells assembled along a parting line, the valve including an elastic ring (14) connected to the internal shoulder of the body (6), receiving the housing (12) of the electronic module therein to hold same, surrounding the parting line between the half-shells thereof.

A valve stem for controlling inflation and deflation is provided. The valve stem includes a valve body having a central passage and a lateral port venting to the atmosphere. A valve core can be positioned within the central passage and configured to permit gas flow into the central passage. A collar is configured to surround an intermediate portion of the valve body, with the collar movable between a first position, where the collar occludes the lateral port to prohibit gas flow out of the lateral port, and a second position, where the collar opens the lateral port to permit gas flow from the central passage through the lateral port. A pressure set assembly can couple to the valve body and be set to a pressure at which the pressure set assembly closes to prohibit gas flow through the pressure set assembly and through the lateral port.

An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, air pump for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, the tire having an elongate valve stem projecting outward from the tire cavity and having an internal valve stem air passageway in communication with the tire cavity and operative to direct pressurized air into the cavity, and a valve housing disposed adjacent an outward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity.

An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, an air pump for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, and a valve housing disposed adjacent an outward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity. The first sidewall has at least one bending region operatively bending within a rolling tire footprint and a sidewall groove defined by groove sidewalls positioned within the bending region of the first tire sidewall. The groove deforms segment by segment between a non-deformed state and a deformed, constricted state in response to the bending of the first sidewall bending region within the rolling tire footprint.

An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, an air pump for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, and a faceted valve housing disposed adjacent an outward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity. The first sidewall has at least one bending region operatively bending within a rolling tire footprint and a sidewall groove defined by groove sidewalls positioned within the bending region of the first tire sidewall.

This invention is a device designed to deflate rubber rafts, inner tubes, air mattresses and other inflatable objects equipped with cut-check valves or self-closing squeeze valves. The device is constructed of a rigid material, the body of which is comprised of a slender conical shape, terminating in a perpendicular T shaped handle. A tapered air gap runs through the core of the slender conical body along the vertical axis of the device. When inserted into said valves, the smooth rounded tip of the device safely penetrates the cut-check or flap portion of the valve, allowing air to flow from the inflatable object, through the device, and into the atmosphere. The tapered body is compatible with valves of various size diameters. When inserted into said valves, friction ensures the device will remain firmly seated inside said valves allowing hands free deflation.

Method for controlling a vehicle including a smartphone-engaging coupling element. Data about operational status of the vehicle is transferred from one or more vehicle-resident systems to a smartphone when the smartphone is engaged with the coupling element. Commands are received by the vehicle from the smartphone when the smartphone is engaged with the coupling element, which commands being based in part on data previously transferred from the vehicle-resident system(s) to the smartphone when the smartphone is engaged with the coupling element. A vehicular system, e.g., seat positioning system, mirror positioning system, passenger compartment temperature control system, route guidance or navigation system, changes its operation in accordance with the commands received by the vehicle from the smartphone when the smartphone is engaged with the coupling element.
