Patent GB-2056144-A (GB)
Title: Low inflation warning device for a pneumatic tyre
IPC: B60C23/06
Filed: 1980-07-23
Abstract: The device is a mechanical sound generating device for attachment to a wheel (119) so that the device is contained within the pneumatic space formed by the tyre and the wheel rim. Whenever a condition of low pressure or overload exists a warning signal is generated. This signal is initiated by contact of the interior surface of the tyre casing with a part (215) of the device, such contact causing a portion (225) of the device to strike an anvil (203) with sufficient force to generate an audible sound. The device is self- setting under the influence of centrifugal force and will generate a warning of insufficient tyre pressure or excessive tyre load. The device will generate a signal at each revolution of the wheel. Under an extreme low inflation condition the device will continue to generate periodic warnings without damage to the tyre. <IMAGE>
