A high temperature warning system for a vehicle steer axle an air pressure supply, a normally-closed valve in fluid communication with pressure supply, a heat sensitive control capable of opening the normally-closed valve upon a predetermined temperature, the heat sensitive control mounted adjacent to the wheel end assembly in a heat exchange relationship therewith, and a warning system connected to the air pressure supply for actuation upon opening of the normally-closed valve.

The invention has proposed a tire valve for controlled filling and emptying of a tire, having a valve body and a filling conduit, which is routed in the valve body from a valve inlet to a valve outlet and in which a filling valve is provided. In order to be able to perform an emptying of the tire, an emptying conduit, which is separated from the filling conduit in a pressure-tight manner, is formed in the valve body and includes an emptying valve, and from this emptying conduit an emptying opening leads through the valve body to the outside, wherein a shut-off element of the emptying valve is coupled to an element, which is movable by means of pressure medium loading, in such a way that a movement of the movable element, which is brought about by means of pressure medium loading in the filling conduit, moves the shut-off element of the emptying valve into an open position.

An electronic air pump pressurizes object in either manual or automatic mode. In automatic mode, the electronic air pump determines air pressure needed to adjust an object to a set target pressure. The electronic air pump inflates or deflates the ball automatically until the air pressure inside the ball matches the preset value. In manual mode regulation of the air pressure is adjusted by a user.

An axle assembly having a constant shaft disposed at least partially through a bearing hub assembly. The constant shaft defines a fluid conduit therethrough. A steering knuckle is disposed at least partially about the constant shaft. The axle assembly may include a bearing spacer disposed about the constant shaft, the bearing spacer being disposed at least partially axially between the bearing hub assembly and the steering knuckle. Additionally, a first rotary seal and a second rotary seal may be disposed radially between the bearing spacer and the constant shaft. The first and second rotary seals may at least partially define a fluid chamber in fluid communication with the constant shaft fluid conduit. Further, a port may be disposed through the bearing spacer, wherein the port is in fluid communication with the fluid chamber.

A joint contains: a body, at least one locking block, at least one controller, and at least one resilient element. The body has an inlet segment, an outlet segment, and an air channel. The outlet segment has a connection orifice. Each locking block has a tooth and a driving portion. The tooth is controlled to move between a first position and a second position. Between the first position and the second position is defined a reverse driving travel path obliquely extending to the inlet segment. Each locking block also has a coupling shaft. The reverse driving travel path is arcuate, and the driving portion and the coupling shaft are on opposite sides of the tooth. Each resilient element urges the tooth to move to the first position and is pressed so that the tooth moves to the second position along the reverse driving travel path.

A pneumatic control device is provided designed to work with self-inflating inner tubes and tires, specifically for bicycles or wheelchairs. The device distinguishes a stem assembly and an air control assembly. The device allows users to set a desired pressure and maintains that constant pressure over time, thereby eliminating the need to manually re-fill the tires. The device is compatible with current rims and tires and requires no modification to be installed to existing rims. The device works by regulating the intake of air from the atmosphere into the self-inflating pumping mechanism. Once the desired pressure is reached, the system stops new air from entering the self-inflating mechanism.

An anti-theft tire valve includes: (a) a sleeve defining an outer wall and an pass-through channel to receive a threaded valve stem and allow a portion of the threaded valve stem to extend through an upper portion of the sleeve; (b) an internal threaded portion positioned within the upper portion of the sleeve configured to securely engage the threaded valve stem; (c) a torque locking surface defined on an external surface of the upper portion of the sleeve; and (d) a valve cap forming a cover and defining an internal thread configured to receive the threaded valve stem and abut an upper rim of the sleeve. The torque locking surface is configured to receive a locking wrench to rotate in a counter direction and press against the valve cap forming a tension lock configured to restrict the removal of the valve cap without the use of an external tool.

A self-inflating tire assembly includes an adjustable valve having: a housing having first end and a second end, and a central bore which extends from the first end to the second end; a piston slidably mounted within the central bore at the first end of the housing, a cap mounted in the second end of the housing forming a chamber with the housing, wherein a spring is mounted within the chamber and having a first end for engagement with the piston and a second end for engagement with a bottom wall of the chamber, said cap further comprising a fluid chamber projecting from the bottom wall of the chamber, wherein the piston is movable to seal the fluid chamber, wherein the housing is made from a material having a higher coefficient of thermal expansion than the material of the fluid chamber.

The filter assembly is positioned between an outwardly threaded stem of a tire valve that controls the flow of tire gas and an internally threaded stem-receiving mount on a tire gas sensor. The filter assembly comprises a housing having relatively opposing first and second ends, a mount-engaging portion adjacent to said first end, a cavity open at said first end, a stem-engaging stub at the second end, and at least one port extending through the stub and into the cavity; a filter insertable in the cavity; and a retainer mountable in the cavity at the first end of the housing and having a bore extending therethrough. The stub at the second end of the housing is disposed to depress the tire valve stem and release tire gas when the filter assembly and the tire valve stem are fully threaded into the mount on the sensing device. The tire gas flows through the port in the stub, the filter, and the bore in the retainer before reaching the sensing device.
