An air maintenance tire assembly includes a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region, air pumping means for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, the tire having an elongate valve stem projecting outward from the tire cavity and having an internal valve stem air passageway in communication with the tire cavity and operative to direct pressurized air into the cavity, and a valve housing disposed adjacent an outward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity.

A tire inflation system and method for a tire supported by a wheel, the tire inflation system including a pump system including a pump cavity configured to fluidly connect to the tire, an actuating element configured to actuate relative the pump cavity, a drive mechanism rotatably coupled to the wheel, the drive mechanism including a motion transformer and an eccentric mass, a valve fluidly connecting the pump cavity to a fluid reservoir; and a control system configured to operate the valve.

An air valve connector includes a head and a switching assembly. The head has a first insertion hole, a second insertion hole, a communicating passage, and an inlet hole. The first insertion hole is provided with a first airtight portion disposed between the communicating passage and the inlet hole, and a second airtight portion disposed between the inlet hole and the first port. The switching assembly includes a plunger movably disposed in the first insertion hole to alternately abut against the first airtight portion or the second airtight portion.

A pumphead comprises a housing having a first end defining an aperture configured to receive a valve head therein; a handle housing defining an air passage in fluid connection with the aperture and an air pump; and a lock arm comprising an end pivotally coupled to the pumphead housing at the end of the pumphead housing opposite the aperture; and a second end disposed between the handle housing and the first end of the pumphead housing. Pivoting the lock arm toward the handle housing locks the pumphead housing around the valve head when the valve head is received in the aperture.

A tyre inflating device (100) includes an air feed line (200), an inflating module (300), including a primary valve (301) movable between a closed position and an open position for closing and opening the feed line (200) and an auxiliary safety module (700), including a secondary valve (500), movable between a closed position and an open position for closing and opening the feed line (200); a pressure sensor (600), configured to detect a pressure value downstream of the inflating module (300) and a control unit (800) programmed to control the secondary valve (500) as a function of the pressure value detected by the pressure sensor (600).

A TPMS-sensor-integrated automatic tire inflation system hose is provided that includes an inspection valve and a TPMS sensor.

A hose kit. The hose kit includes a manifold. The manifold includes an air input, a first air output and a second air output. The hose kit also includes a first air output hose configured to attach to the first air output and a first tee fitting configured to attach to the first air output hose. The hose kit further includes a first tire whip configured to attach to the first tee fitting and a first tire hose configured to attach to the first tee fitting. The hose kit additionally includes a second air output hose configured to attach to the second air output and a second tee fitting configured to attach to the second air output hose. The hose kit moreover includes a second tire whip configured to attach to the second tee fitting and a second tire hose configured to attach to the second tee fitting.
