Abstract of the Disclosure A sprayer spraying liquid or pulverulent substances, particularly fire-extinguishing or fire-inhibiting substances, comprises a tank adapted to hold the substance to be sprayed, a sprayhead, a rising pipe extending from said tank to said sprayhead, and a pressure vessel, which contains a gaseous fluid and communicated through a shutoff valve with the tank. In order to ensure that the sprayed substance will be uni- formly spread over a large area, the sprayhead is composed of a base, which is coaxially connected to the rising pipe and flares preferably like a cup, and a coverlike top, which is adapted to be tightly seated on said base and is adapted to be lifted from said base as far as to a stop, which can be adjusted in height, said top is adapted to be raised against a bias which is due to gravity and/or spring means, and an annular gap is held open between the base and the raised top by the substance as it is expelled in response to an actuation, preferably a sensor-controlled automatic actuation, of the shutoff valve connected between the pressure vessel and the tank.
