BODY OF FLAME SPRAYING BURNER Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: the body of burner carries wheel provided with interior cam profile and mounted for rotation around the geometrical axis of the powder feed channel with preservation of contact of the second end of pusher with the interior cam profile of the wheel. The cam profile of the wheel is in the form of the Archimedes spiral the pitch of which is equal to the diameter of the powder feed channel and the radius of the pitch circle is equal to the distance from the geometrical axis of the channel to the second end of the pusher in the initial position. The body is provided with annular groove for arrangement of the wheel with the cam profile, with the radial groove whose surface serves as a guide for the pusher, and with the locator fixing the position of the cam-profiled wheel and consisting of one locking member and a number of evenly-spaced locating sockets. The cam profile is supplemented by a number of evenly-spaced projections whose apices are in contact with the pitch circle. The number of the locating circuits is two times the number of the projections of the cam profile. EFFECT: extending operating capabilities. 3 cl, 5 dwg
