Abstract (en)

[origin: EP1555044A2] The fire protection for air ventilation channels and air outlets, and the like, is an inserted housing (1) with a valve seat (2) and a valve closure body (3) held in the open position against a spring to give a rapid closing action at a given temperature. The spring is around the valve stem (5), which rides within a guide sleeve (6) in the housing. A lock (7) holds the valve in the closed position, by an expansion spring (8), with legs (10) which open out against a locking seat at or in the sleeve on moving between the open and the closed settings.
