APPARATUS FOR MONITORING FLUID-TIGHTNESS OF A CHAMBER FILLED WITH A GAS

Known apparatuses measure and correct temperature-induced pressure fluctuations of the gas enclosed in the chamber. Used for this purpose is a temperature-sensitive reference-pressure capsule, which, however, is ineffective in the event of leakage. The novel apparatus is intended to detect the press...

Beschreibung
Zusammenfassung:	Known apparatuses measure and correct temperature-induced pressure fluctuations of the gas enclosed in the chamber. Used for this purpose is a temperature-sensitive reference-pressure capsule, which, however, is ineffective in the event of leakage. The novel apparatus is intended to detect the pressure fluctuations with means which are independent of the gas pressure. The temperature-sensitive apparatus is formed from an element (14, 19, 20, 24) which changes its extension with the temperature and is arranged between a pressure-measuring device (6, 11) and a valve (7, 8; 9, 10) serving as a signal transmitter. The apparatus can be used for monitoring the pressure of a vehicle tyre.
