Abstract:
A sprinkler or a spray head comprising a housing (2), an inlet (3), a nozzle (4) mounted in the housing, a passage (17-18-13) from the inlet to the nozzle, and a holder (8) for a release means (7), the holder being mounted in front of the nozzle so that it prevents the nozzle from spraying extinguishing medium forward without hindrance, the nozzle being arranged to spray extinguishing medium once the release means has been released, the holder (8) being mounted in the housing (2) by means of a locking mechanism (20), which is arranged to open and release the holder (8) from the housing once the release means (7) has been released, a spindle (9) being arranged to move, when the release means (7) is being released, from a first position in the housing, in which the spindle is arranged to close the passage so as to keep the nozzle closed, to a second position, in which the spindle is arranged to open the passage so as to keep the nozzle open, the spindle (9) being arranged to exert a force on the locking mechanism (20) and, by moving toward the holder (8) into the second position in connection with the release, to open the locking mechanism so that the nozzle (4) can spray extinguishing medium, characterized by the spindle (9) comprising a conduit (13) leading to the nozzle (4) and forming part of the passage (17-18-13) so that the nozzle can spray extinguishing medium forcefully forward essentially without hindrance when the spindle is in the second position.
