Abstract
A safety valve responding to overheating conditions of the surrounding atmosphere, more specifically a combustion gas inlet valve that closes when a fire declares. The valve uses a shape-memory element for detection and command. For the latter function it must be inside the valve, at the expense of sufficiently rapid detection of external temperature. This problem is solved by using a shape-memory element that is in close contact with the valve housing, e.g. countersunk in a groove in the internal wall of the valve housing, for facilitating conduction heat transfer.
