A pneumatic valve for a tire having a stem fluidly coupled to a pressure vessel is provided. The pneumatic valve includes a core body that couples to the stem, the core body having an interior passageway. A cap is coupled to the core body, the cap having a concavity on an outer diameter and a bore hole extending from one end, the bore hole being in selective fluid communication with the interior passageway. The cap further has an interior portion, the core body being at least partially disposed in the interior portion. A valve seat is disposed in the interior portion between the core body and the cap member. A sealing plug is moveably disposed at least partially in the interior passageway and at least partially within the bore hole. A biasing member is disposed in the interior passageway and arranged to bias the sealing plug against the valve seat.

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 pressure medium loading, in such a way that a movement of the movable element, which is brought about by the pressure medium loading in the filling conduit, moves the shut-off element of the emptying valve into an open position.

A tyre pressure sensor is mounted at the distal end of a valve stem mounted on a wheel. A protective assembly comprises a body which is releasably attached to the wheel, and a cap which is releasably attached to the body. The valve stem and pressure sensor are enclosed within the body and the cap.

A valve assembly is configured to secure on a hole of a rim on which a tire having at least two air chambers is mounted. The valve assembly includes a main body, a securing means, at least two valve bodies and at least two valves. The main body includes at least two transfer air passage respectively connected to each of the air chambers. The securing means is configured to secure the main body and also the at least two valve bodies on the rim. The at least two valve bodies are respectively disposed on the main body and each of the at least two valve bodies has an inlet air passage connected to one of the transfer air passages of the main body. The at least two valves are respectively attached to each of the at least two valve bodies.

A dividing wall mounting device includes: a main device body extending along a central axis of a through-hole; and a flexible flange protruding laterally from an intermediate position of the main device body, and when the dividing wall mounting device is inserted into the through-hole from one end side in the axial direction, the flexible flange passing through the through-hole in a first state of collapsing towards another end side in the axial direction to narrow due to contact with an opening edge of the through-hole, and when the dividing wall mounting device is pulled back in a direction opposite to the insertion, the flexible flange being press-fitted into the through-hole in a second state of collapsing towards the one end side in the axial direction to narrow due to contact with the opening edge and having an outer diameter larger than an outer diameter in the first state.

An inflation viewing device has a main body which is externally provided with a transparent viewing portion and internally provided with an inner passage where an air path assembly is arranged. An air entrance connector is operatively connected to an external air source and to a first end of the main body. An air exit connector is connected to a second, opposed end of the main body and to an inflation valve. A guide spacer is provided between the air entrance connector and the main body. The guide spacer has an inner passage having a wider section in communication with the inner passage of the main body and a reduced section defining a communication opening with the air entrance connector. A filter is arranged in the communication opening. A plunger, biased by a spring, is slidably arranged within the inner passage of the guide spacer and guide section of the main body inner passage.

An inflation valve for a tubeless tire may include a valve body defining a cavity having a proximal opening and a distal opening. A valve stem extends through the cavity and includes a plug at a proximal end of the valve stem. The proximal opening of the cavity is defined by a beveled surface, and an outer diameter of the beveled surface is larger than an inner diameter of the valve body. The valve is transitionable between: a) a closed position, where a resilient surface of the plug engages the beveled surface to seal the cavity, and b) an open position, where the resilient surface of the plug is spaced from the beveled surface to unseal the cavity.

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 pressure sensitive valve core usable within a valve stem of an inflatable or pressurized apparatus and configured to automatically maintain a manufacturer's recommended air pressure within the inflatable or pressurized apparatus throughout fluctuations in temperature and elevation, and to regulate the amount of air pressure being put into the inflatable or pressurized apparatus according to a manufacturer's recommended air pressure. The pressure sensitive valve core includes a body and a spring valve mechanism including a spring designed according to Hook's Law to automatically close the spring valve mechanism against the body when a predetermined amount of pounds per square inch (PSI) is inserted into the inflatable or pressurized apparatus.
