Abstract (en)
An automatic on-off fire extinguishing sprinkler head including a housing (13) defining inlet (21) and outlet (22) openings; a valve (12) retained by the housing and disposed between the inlet and outlet openings, the valve being movable between a closed position in which it prevents fluid flow between the inlet and outlet openings and an open position in which it allows fluid flow therebetween and a latch (14) releaseably latching the valve in the closed position. A release mechanism (15) responds to a sensor (16) by releasing the latch to allow movement of the valve into the open position at a predetermined ambient temperature. Operatively coupled to the valve is a temperature responsibe actuator (17, 70) shaped and arranged to allow movement of the valve into its open position in response to ambient temperatures above a given level and to force the valve intoi its closed position in response to ambient temperatures below the given level.
