Siphon tube is made of constant cross section with a diffuser on the end facing the bottom of the cylinder. In the top of the cylinder a fitting is mounted which has a check valve for gas injection. The sprayer comprises a hollow body in the form of a sphere, which has an inlet hole and outlet throttle element. Housing is located between the nozzle and the holder, with the inlet hole plane of the housing is located perpendicular to the axis of symmetry of the nipple and the holder. Output throttling element is made in the form of cylindrical holes, equally spaced on a spherical surface of the housing. The axes of the holes are arranged on radial lines that connect the center of the spherical surface of the housing to the center of the hole.

EFFECT: increased efficiency of fire fighting by increasing the operating speed.
