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 vehicle includes: a sensor for measuring a relative position and a relative speed between an obstacle and the vehicle; an injector for injecting a deforming material which is solidified during injection to absorb an impact and enhance coupling strength at a portion to which the deforming material is attached; and a controller configured to determine a collision probability with the obstacle based on the measured relative position and the measured relative speed, to determine a predicted collision position when the collision probability reaches a reference collision probability, to determine an injection direction of the injector based on the predicted collision position, and to control the injector to inject the deforming material in the determined injection direction.

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.

An anti-spray joint structure for a connection of an air nozzle of a tire and a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has an anti-spray connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. The cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. The valve bolt includes a post, a connecting disc, multiple spaced slots, and a first seal ring. A lock element includes at least one tangent plane, a stem, and a hollow cavity.

The second segment has an anti-spray connector including a fitting sleeve. The fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room. A valve bolt includes a post, a connecting disc, spaced slots, and a first seal ring. A lock element includes a hollow cavity, a hexagonal tab, and a tilted extension.

A valve connector comprises a connecting member, a threaded member, a joint member, and first and second connection assemblies. The connecting member is inserted into a axial hole of threaded member to cause a abutting portion of the connecting member entering into the axial hole. The joint member forms two threaded sections at two opposite ends thereof. The two threaded sections are alternatively detachably connected to a threaded portion of the threaded member so that a first seal ring of the first connection assembly and a second seal ring of the second connection assembly are alternatively removably abutted against the abutting portion for connecting a Schrader valve and a Presta valve.

A valve cap assembly for being attached to an air valve and removably covering an end of the air valve includes a hoop, a cap, and an arched tether connecting the hoop and the cap. The hoop attaches the valve cap assembly to the air valve. The cap removably covers the end of the air valve to protect the end of the air valve. Both the hoop and the cap form a dependable interference fit between the hoop or cap and the valve stem to retain the hoop on the valve stem and to retain the cap covering the end of the air valve on the air valve. The arched tether enables the cap to be sufficiently spaced away from the hoop to place the cap over the hoop while remaining between the cap and the hoop on one side of the air valve when the valve cap assembly is attached to the air valve with the cap covering the end of the air valve.

A safety valve replaces a tire valve. The valve includes a generally elongate hollow main body having an upper portion, a lower flex hose connector, a side tubular branch having a valve seat with a ball valve, an electronics housing having a battery, motor and a drive pin for the ball valve. The lower flex hose connector is adapted for connection to a flex hose or valve stem of the vehicle tire. The side branch branches from the main body and communicates with the hollow interior of the main body. The side branch has a plurality of air exit apertures at its periphery. The valve seat includes a base with an aperture therein through which the drive pin can extend through to engage the ball valve. The ball valve sits in the base and is biased in the valve seat via a spring to cover the aperture.

A device for inflating a tire includes a forward sleeve including an internally threaded head; an air intake assembly including a joining member secured to the forward sleeve and having a constricted section and an air inlet; an air intake extending out of the joining member at an acute angle and having an air channel for communicating with the air inlet through the constricted section, and a connector; and a rear sleeve secured to the joining member; and a valve assembly including a rod through both the rear sleeve and the joining member; a mounting sleeve in the forward sleeve and having a groove at a first end, the groove being in the internally threaded head, and a fitting hole communicating with the groove; a flexible tubular member in the mounting sleeve; a handle secured to the rod; and a snap ring on the rod.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.
