A pressurizable adapter of bicycle valve can be used for a tubeless bicycle tire and contains: a receiving tube, a valve core and a valve cap. The receiving tube includes an internal screw portion, an air outlet, a first connecting part, an air inlet, at least one sealing ring and a connecting section. The valve core used is a standardized valve core. The valve core is housed in the connecting section of the receiving tube, the second connecting section of the valve core is connected to the first end of the receiving tube, and the second connecting portion of the valve core is in contact with the first connecting portion of the receiving tube, so that a closing effect is achieved. The valve cap contains a third connecting portion configured to connect to the first connecting portion and covers the air inlet of the receiving tube.

The present invention provides a pneumatic valve system for easily attaching and sealing a valve coupler to a valve stem for filling an inflatable vessel such as a tire, tube, mattress, etc. The valve system may comprise the following major components: a valve stem, a valve cap with a pin passage and attachment structure for attaching to a valve coupler, a sealing member, a biasing member, the valve coupler comprising a coupler housing, a pin seat, an inflation pin, and a collar with ball bearings complementary to the attachment structure of the valve cap, and an elastic sleeve for providing inward force against the ball bearings. The valve system may allow for easy, secure, and sealed engagement between the valve coupler and valve stem by simply pushing down on the valve coupler, and disengagement by pulling up on the valve coupler with as little as two fingers.

A valve core includes: a barrel part that is cylindrical; a barrel packing that surrounds an outer lateral surface of the barrel part; a washer through which the barrel part penetrates and which abuts on the barrel packing from above; and a head part that includes a male screw part at its outer lateral surface and that rotates relative to the barrel part, wherein a lower surface of the head part abuts on the washer from above.

An inflation manifold connected to dual pneumatic tires by air hoses provides a central location for tire inflation and location of pressure sensors. A hose block connected to dual pneumatic tires by air hoses provides a central location for location of pressure sensors. The pressure sensors may be TPMS sensors or a combination of TPMS sensor and pressure gauge.

Systems and methods are provided for providing a tire pressure enhancing device for increasing the air pressure of tires mounted on a vehicle. For example, an air compressor may be coupled to an engine of a vehicle to compress air. The compressed air is then stored in the frame of the vehicle. The compressed air may be transferred to each tire through a hose via an access point in the frame.

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.

An air pipe device of an air compressor contains a connector of an air pipe configured to output fluid pressure so as to inflate airs and to feed sealant when the air compressor operates. The air pipe device contains a connection pipe, and the connection pipe includes an open segment defined on a first end thereof and configured to connect with the connector of the air pipe of the air compressor. In addition, the connection pipe includes a stop segment formed on a second end thereof, such that the connection pipe is configured to connect a twin tire with the connector of the air compressor so as to inflate airs and feed sealant.
