The invention relates to sprinkler comprising a frame (2, 8, 2', 2"), into which at least one nozzle (15, 15', 15") has been mounted whereby the frame has a fluid inlet (5, 5' 5") and a passage (13, 13' 13") for conveying extinguishing medium to at least one nozzle (15, 15', 15"), whereby the sprinkler, in a standby state, has a heat-sensitive release means (22, 22', 22"), which is in contact with a spindle (16, 16', 16") slidably arranged in a conduit (13, 13', 13") having an inlet (11) and an outlet (14) to said nozzle. To provide a new sprinkler that ensures an even and straightlined load on the release means (22) without breaking the release means due to a high fluid pressure, the sprinkler is characterized in that the conduit is composed of a channel (13, 13', 13"), the wall of which the spindle (16, 16', 16") is arranged in a slidable or almost slidabl e contact with, and that the spindle and the channel extend on both sides of the channel (13, 13', 13") inlet (11, 11', 11") in order to at least partial ly balance the fluid pressure in the inlet when the sprinkler is in the standby state.
