KOCHETOV'S SPRINKLER Russian patent published in 2017 - IPC A62C31/00 

FIELD: fire safety.

SUBSTANCE: sprinkler contains the housing, the spray device and the automatic activation element of exceeding the nominal room temperature. The body is made in the form of the straight case with windows at its lateral surface. At one end of the straight case, facing towards the spray device the partition is disposed. The spray device is designed as the socket formed by the part of spherical surface with thickness "s" and in which the radial slots are made. The socket is attached to the end surface of the case by means of arcs, disposed along the conical surface, the upper part of which is fixed at the partition, and the socket is attached to the lower part, which is the part of the spherical surface, limited by the inner and outer hemispheres and having the thickness "s", lying in the range 1÷5 mm. The hemispheres center lies on the line, joining the straight case axes and the partition axis. There are the grooves on the spherical surface from its outer side, the axes of which are located at radial with respect to the hemisphere lines, and in the peripheral part the of the hemispheres there are at least three throttle holes, the centers of which lie in the plane parallel to the diametral hemispherical plane, which is perpendicular to the straight case axis, and the axes of which intersect at the point lying on the straight case axis, and form the acute angle with this axis in the plane of the drawing.

EFFECT: increase of the fire extinguishing effectiveness by the spray device introduction, which allows to obtain the fine flow of the fire extinguishing liquid or the foaming agent solution.
