NOZZLE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: nozzle has mixing housing, nozzle, and fuel supply pipe connected with the mixing chamber. The mixing chamber is arranged in the housing to define a ring space. The fuel supply pipe is connected with the mixing chamber through a conical insert provided with tangential passageways. Additional inserts are interposed between the conical insert and nozzle. Each of the inserts is constructed as hollow cylinder and trancated cone. Shaped logarithmic spiral passageways are provided in each trancated cone. The fuel supply pipe and ring space are connected with the mixing chamber through the tangential passageways made in the conical insert and shaped passageways respectively made in each of the trancated cones of the additional inserts. The mixing chamber is defined by the additional interconnected and arranged between the conical insert and nozzle diverging in the direction of the nozzle. EFFECT: improved design. 2 dwg
