Abstract
An inflation device for a wheel with a pneumatic tire. A valve having a seat carried by a body and a head separates a chamber from an output connector. The head is movable within the chamber between a closed position wherein it is in abutment on the seat and an open position wherein it is separated from the seat so as to put the radial openings into communication with the output connector. The head is elastically held in the closed position against the seat so as to allow lifting of the head when the pressure in the output connector is greater than a predetermined threshold.

An inflation device for a wheel with a pneumatic tire, the device comprising a body intended to be fastened to the wheel by an output connector discharging into the tire, the body comprising radial openings discharging into a chamber contained in the body and to an outer surface of the body, the chamber being separated from the output connector by a valve comprising a seat carried by the body and a head, the head being carried by operating means so as to be movable inside the chamber between a closed position wherein it is in abutment on the seat and an open position wherein it is separated from the seat so as to put into communication the radial openings and the output connector, wherein the operating means comprise elastic holding means acting elastically on the head in the closed position opposite to the seat so as to allow lifting of the head when the pressure in the output connector is greater than a predetermined threshold.
