Abstract (en)

[origin: EP2278150A1] The device has housings (38, 40), and an operating chamber (66) provided in communication with a fluid system i.e. fuel system, of an internal combustion engine. A gas volume (58) is sealably closed by membranes (54a, 54b) i.e. metallic pipes, provided within the operating chamber, where the membranes are made up of metal. The membranes are limited by a thin wall and arranged parallel to each other, and the closed gas volume includes pressure i.e. overload pressure, and is provided with a closable opening (60). Edges of the membranes are sealably connected with each other.
