A multifunctional external inflating valve and a mounting method for a loading device are disclosed. An inflating valve body of the inflating valve includes a three-way through main body through from a side surface by a side surface connecting part connecting a loading device. A valve core is arranged in an axial middle hole. A hole cavity is formed in the front portion of the axial middle hole and connected to an original tire inflating valve. An outer conical surface is arranged on the front portion of the valve core. The front portion, comprising the outer conical surface, of the core protrudes out of the front end of the hole cavity of the main body. An core conical surface sealing rubber pipe is mounted on the outer conical surface of the core and seals the core and a conical hole sealing surface of a tire inflating valve inner hole cavity.

An air pressure regulation system and method are provided. The system includes a pressure regulation system configured to be mounted within an axle of a moving vehicle having a tire mounted thereto. The pressure regulation system includes a pump assembly configured to continuously pump a gas into the tire. A release valve is configured to enable gas above a set pressure to pass from the tire through a second pneumatic fitting into the atmosphere. The release valve selectively closes after the air pressure within the tire no longer exceeds the predetermined level.

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 assembly for a tire inflation system includes a ring portion. The ring portion has an outer surface and an inner surface. A first projection and a second projection each extend from the inner surface. A valve assembly is connected to the ring portion and disposed in from the outer surface.

A valve core includes: a core body screwed with a female screw part of a core mounting hole and formed of a seal ring, and a support base including a male screw part and a sleeve part; a shaft part penetrating through the support base; a valve body provided at a tip of the shaft part; an overhang part provided at the sleeve part so as to laterally overhang from a basal end of the sleeve part; a plate part provided at the support base so as to project to a basal end side from the basal end of the sleeve part and having a pair of flat tool abutting surfaces; and a shaft receiving hole penetrating through the plate part. The seal ring has a shape of a ring whose cross-sectional shape is quadrangular and the overhang part and the seal ring abut on each other by their surfaces.

An air chuck includes a body and a valve core interface. The body includes output, interface, and input ports. The body defines a first passageway that extends between the output and interface ports. The input port defines a second passageway that is in fluid communication with the first passageway. The valve core interface is slidably coupled with the body and is slidable between extended and retracted positions. The valve core interface includes a shaft and a knob. The shaft includes proximal and distal ends. The distal end is at least partially disposed in the first passageway. The knob is coupled with the proximal end of the shaft. The shaft is rotatably coupled with the body and is selectively rotatable in either tightening or loosening directions via the knob. The distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem.

An inflation device is provided including a shell, a pin, a restraining element, and a barrier. The shell may be coupled to an inflation canister. The pin is positioned within the shell in order to open a seal of the inflation canister. The restraining element is positioned within the shell and is positioned to prevent the pin from opening the seal of the inflation canister. The restraining element is dissolvable. The barrier is positioned within the shell. The barrier includes a fluid resistant skin and a heating element coupled to the fluid resistant skin. The heating element may open a portion of the barrier responsive to an electrical current running through the heating element.

An Automatic pressure valve for the inflation-deflation of pneumatic arrangements comprises a main body (102) with an inlet connector (103) communicated with a pressurized air supply network an outlet connector connected to a pneumatic arrangement and a mechanical means which allows for a total or partial air passage or blockage to perform inflation-deflation operations of the pneumatic arrangement in a faster and practical way. The mechanical means comprises a main movable plunger (116) having an inner stepped through channel (117), a spring (120) arranged on a seat (121) defined in the inner stepped channel (117), an inflation plunger (122) operatively retained by said spring (120), a proximal movable end (126) within a first inner chamber (105), a reduced middle section (119), and a distal movable end (128) having a smaller diameter than the proximal end (126) and arranged within a second inner chamber (106).
