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 valve assembly, a valve adapter and a bicycle tire are provided. The valve assembly includes a valve stem having a passage. A cap member is fluidly coupled to the passage and has circumferential concavity on an outer diameter adjacent an end. A core body is coupled to the valve stem and has a an axial opening. A biasing member is disposed within the axial opening. A seat is coupled between the core body and the cap member. A first sealing member is movably disposed between a first and second position, the sealing member being biased against the seat by the biasing member, the sealing member having a first end adjacent the seat and a lower portion. A second sealing member is operably coupled to the passage to selectively seal at least a portion of the passage, in response to movement of the lower portion.

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 cap includes one or more longitudinal protrusions that form the interference fit.

The present invention relates to novel calibrated gauges for use with tire deflators which improve their ease of use, accuracy and consistency. Particularly, these novel gauges enable users to precisely set or maintain the distances between various fixed points on a tire deflator, which correspond to a desired tire pressure, enabling the simplified, precise and reliable setting of that tire deflator. This is a huge improvement as most tire deflators rely on inherently unreliable trial and error calibration of their air pressure settings which may change over time and without indication. More particularly, the present invention enables faster setting times for tire deflators with more reliable results, easier changes between pressure settings, and more accurate tire pressures. Embodiments of this invention include various gauges customized in dimension and material for use with different model tire deflators to achieve various tire pressures as desired.

A valve stem cap assembly for inhibiting a valve stem cap from being lost when the valve stem cap is removed from a valve stem includes a cap that is threadable onto a valve stem of an inflatable tire. In this way the cap inhibits debris from collecting in the valve stem. A tether is rotatably coupled between the cap and the valve stem. In this way the tether inhibits the cap from being lost when the cap is removed from the valve stem.

A reflector for a vehicle wheel, or a bicycle wheel, contains an air valve attachment, and a reflective surface affixed to the air valve attachment. The reflective surface contains a portion which is aligned perpendicular to the axis of the air valve attachment. A bicycle wheel and a kit are also described herein.

A coupling for valve assemblies, for tubeless tires, includes an enclosure arranged to cover a rigid rim of a vehicle, to delimit a substantially tubular compartment, filled with gas under pressure. The coupling has a first element and a second element crossed respectively by a first through channel, threaded internally, and by a second through channel. The second element cooperates with a valve for the selective closure of the second channel. The first element rests on an internal surface of the rim, which can be activated following its hermetic insertion, from the inside of the compartment. The second element rests on an external surface of the rim, which can be activated following the hermetic screwing, from the outside of the compartment, of a threaded stem of the second element in the first channel, with consequent alignment between the channels to connect the compartment to the outside.

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 pressure equalization valve assembly may include a valve body forming fluid chamber configured to receive pressurized fluid from a fluid pressure source, a first port configured for sealed communication with a first vehicle tire, and a second port configured for sealed communication with a second vehicle tire; a first one-way valve disposed in the valve body between the fluid chamber and the first port so as to allow one-way fluid communication from the fluid chamber to the first port when the first one-way valve opens; a second one-way valve disposed in the valve body between the fluid chamber and the second port so as to allow one-way fluid communication from the fluid chamber to the second port when the second one-way valve opens; and a two-way valve disposed in the valve body between the first port and the second port so as to allow two-way fluid communication between the first port and the second port when the two-way valve opens.

The invention relates to a tyre valve for a pneumatic tyre of a vehicle, having a valve stem extending from the air inlet end to the air outlet end and having an outside thread on its outside circumference and a collar at its air outlet end for a rim well carrying the pneumatic tyre and a fastening thread for an air pressure sensor or other device to be fastened to the valve stem and positioned inside the pneumatic tyre, exhibiting a union nut with an inside thread for screwing onto the outside thread in order to clamp the rim base between the union nut and the collar, with the valve stem being inserted through a rim bore, with a plastic valve cap, with a deformable element located on the outside circumference of the valve stem and/or an inside circumference of the union nut. The tyre valve according to the invention is characterised in that the union nut and, if the deformation element is located on the inside circumference of the union nut, also the deformation element, exhibit a minimum inside diameter that exceeds the maximum outside diameter of the valve cap.
