Abstract

Abstract Device fitted on a wheel for maintaining the pressure in a tyre, comprising a compressed-air vessel and a pressure regulator triggering an alarm in case of puncture. The invention relates to a device for maintaining in the tyre of a moving vehicle the recommended air pressure and, in the event of a puncture, transferring an air reserve and triggering an alarm. It consists of a vessel (1) fixed to the rim (2) and connected to a pressure regulator (4) connected to the tyre (28), and also to a central alarm unit activated by the contacts (49)-(50). When the pressure is too low the regulator compensates with air from the vessel until this is exhausted, and indicates by way of an earthing contact to an alarm which of the wheels is punctured. The device according to the invention is particularly intended for vehicle wheels fitted with pneumatic tyres. <IMAGE>
