A valve for a bicycle tire having a rim is provided. The valve includes a stem body having a first and second end with a first opening. A cap is coupled to the second end, the cap having a pin passage therethrough, the cap having a circumferential concavity on an outer diameter. A valve seat is disposed between the cap and the second end, the valve seat having a second hole that fluidly couples the first opening and the pin passage. A spring is disposed within the first hole. A seal is movably disposed within the first opening and biased against the valve seat by the spring, the seal being movable between a first position and a second position.

A device (100) for measuring the pressure of a tyre (2) mounted on a rim (1), comprising: a valve (110) mounted on the rim (1) and comprising a first channel (112), a pin (115) mounted so as to be able to move in translation in the first channel between an open position and a closed position; an intermediate body (120) mounted on the valve and that delimits a second channel (122) extending the first channel and receiving a fastening rod (130) for fastening the intermediate body to the valve, the fastening rod having a first end designed to move the pin from the closed position to the open position, and an intermediate portion closing the second channel; a pressure sensor (140) received in a third channel of the intermediate body leading into the second channel; and means (150) for retaining the pressure sensor in the third channel of the intermediate body.

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.

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.

A mechanical fluid pressure regulator comprising: a regulator portion for housing a valve assembly, and a manual adjustment portion. The regulator portion having a supply port for receiving a supply pressure and a delivery port for providing a delivery pressure; the delivery port being in selective fluid communication with the supply port. The adjustment portion having a structure at least partially disposed therein. The structure is adjustable for establishing the delivery pressure at a set target and comprises a locking mechanism. The locking mechanism generating prevailing torque to prevent unintentional adjustment of the structure.

A high-volume tire valve is provided, wherein the high-volume tire valve includes: a tubular member including a passageway, a shoulder and a necked portion, the passageway including first and second passageways located by two sides of the shoulder, the necked portion being located in the passageway and extending radially inward; a valve core received in the passageway, including a tubular body and an end portion connected to the tubular body, the tubular body defining an axial hole and including at least one lateral hole in communication with the axial hole, an end of the axial hole being open; a seal disposed on the valve core and located in the second passageway, an outer diameter of the seal being greater than a diametric dimension of the first passageway; and a stopper resiliently squeezed into the second passageway and axially blocked by the necked portion.

A tire valve is provided, wherein the tire valve includes: a tubular member including an internal channel, a shoulder and a necked portion, the shoulder and the necked portion projecting radially inward in the internal channel; and a valve assembly resiliently squeezed through the necked portion and axially blocked by the necked portion to be disposed in the internal channel and restricted between the shoulder and the necked portion, and being operable to block or unblock the internal channel, wherein the valve assembly includes a valve pin, the valve pin includes an axial hole and at least one lateral hole in communication with the axial hole, and the at least one lateral hole is in communication with the internal channel.

A tire valve is provided, wherein the tire valve includes: a tubular member including an inner surface, an internal channel and an enlarged section, the internal channel being defined by the inner surface and extending through the enlarged section; and a valve assembly including a sealing portion, movably inserted in the internal channel, and being operable to drive the sealing portion to engage with the inner surface to block the internal channel or disengage from the inner surface to unblock the internal channel; wherein when the tubular member is disposed through a rim, the enlarged section is inserted in an internal room of the rim, and a position where the sealing portion engages with the inner surface is located in the internal room of the rim.
