A compressor unit (38) for supplying pressurized medium to a tire mounted on a vehicle wheel rim (34), having a compressor (58) for exerting pressure on a fluid medium that is to be conveyed into the tire. The compressor unit (38) is dimensioned to be accommodated in a center bore (44) of the vehicle wheel rim (34) when the vehicle wheel rim (34) is in the mounted state on a wheel hub (62); and the compressor (58) can be driven by a drive unit (56) positioned in the vicinity of the center bore (44) of the vehicle wheel rim (34). The compressor unit (38) is usable with a vehicle wheel rim (34) having a pressurized medium supply device (22) for a tire that is mounted on the vehicle wheel rim (34), as well as a vehicle having a vehicle wheel that includes such a vehicle wheel rim (34).

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.

The invention relates to a device for coupling a tire pump to a valve of a tire and for providing a fluid flow path from said pump to said valve, comprising a pump nipple for covering said valve. The device comprises an elastic band coupled to a body of said device, said band being embodied for positioning around said tire under elastic force. A preferred embodiment comprises a set of device and at least two pump nipples for use with the device. The invention also relates to a method of inflating a tire.

An inflation pump including a body having a cylinder and a head integrally formed with the cylinder. The cylinder includes a pressurizing space. The head includes a through-hole extending along a longitudinal axis. An intercommunication passage is disposed between and intercommunicates with the through-hole and the pressurizing space. A pressurizing unit is slidably received in the pressurizing space and is reciprocally slidable relative to the body. A nozzle unit includes a pressing device disposed in the through-hole. The pressing device includes a push seat having a check ring. The check ring includes an inner side abutting against the push seat and an outer side abutting against a portion of an inner periphery of the through-hole. The portion of the inner periphery of the through-hole is located between the intercommunication passage and the coupling end. The check ring permits air to flow only from the intercommunication passage towards the coupling end.

A system for an air inflation tool including an air regulator assembly, a clamp assembly, a hose assembly and a housing assembly is disclosed. The air regulator assembly includes an air regulator used to regulate air flow from an air supply. Attached to the air regulator is a clamp from the clamp assembly that permits the air supply to be attached to the air regulator. Attached to an opposite end of the air regulator is an output hose of the hose assembly. The output hose is attached to a tire at an opposite end. When the air regulator determines that the air pressure of the tire is too low, the air regulator will permit for air to continue flowing to the tire through the outlet hose. Otherwise, air flow from the air supply will cease when the air pressure of the tire is as needed.

A pump head configured to secure various air valve types is disclosed. The pump head may include a housing defining an aperture sized and shaped to receive a valve head therein; a moveable pin disposed within the housing defining a pin notch disposed about an exterior circumference of the moveable pin; a first taper unit disposed in the housing; a second taper unit disposed in the housing and adjacent to the first taper unit, the second taper unit biased away the first taper unit; and an elastic ring disposed between the first and second taper units, wherein the second taper unit is moveable towards the first taper unit, thereby compressing the elastic ring circumferentially in at least one of two positions, the elastic ring compressed about the pin notch in the first position and about the valve head in the second position.
