Device for supplying a gaseous fluid for a gaseous fluid circulation circuit and filtering device equipped with such a device for supplying a gaseous fluid

摘要

The device has a mobile membrane (7) to separate a case (2) into compartments (2A, 2B). The case has connection units (3, 4) respectively connecting the compartment (2A) with a gaseous fluid supply circuit and the membrane with an obturator (11) e.g. valve, of an additional gaseous fluid supply inlet (25) of the circuit. The membrane is deformed by pressure variations in the compartment to open the inlet. Springs (8, 9) return the membrane to a closed position of the obturator, and are pre-stressed by a temperature probe (6) extensible based on temperature outside and inside the circuit.
