LIQUID SPRAYER Russian patent published in 2006 - IPC B05B1/30 

FIELD: fire putting out.

SUBSTANCE: liquid sprayer comprises housing whose face is provided with outlet opening and controller of fluid flow rate. The liquid flow rate controller is mounted in the space of the housing and comprises chamber with movable piston, axisymmetric deflector set in the outlet opening in the housing, and rod. One end of the rod is connected with the deflector, and the other end, with the piston. The chamber of the liquid flow rate controller is divided into two spaces by the piston. The first space is in communication with the housing space through which the liquid is supplied to the outlet opening. The second control space is isolated from the space of the housing, pressure-tight, and filled with gas. The deflector has at least one profiled section that is conical or conoid in shape and projects out of the exit of the outlet opening in the housing. The cross-section of the profiled section of the deflector increases in the downstream direction. According to the other version, the control space of the liquid flow rate controller receives the spring. The chamber of the liquid flow rate controller is cylindrical and mounted coaxially to the outlet opening in the housing. The maximum diameter of the deflector is smaller than that of the outlet opening in the housing. The sprayer is provided with the axisymmetric expansion chamber arranged coaxially to the deflector at the exit of the outlet opening in the housing. The grid or perforates baffle is set at the outlet section of the expansion chamber. The chamber can move along the axis of symmetry of the deflector with respect to the housing of the sprayer.

EFFECT: expanded functional capabilities.
