MULTI-CONE, MULTI-STAGE SPRAY NOZZLE Russian patent published in 2021 - IPC B05B1/30 B05B1/32 F22G5/12 B05B12/04 

FIELD: mechanical engineering.

SUBSTANCE: multicone multistage spray nozzle is proposed, comprising a nozzle body (102) and an outer (104) and an inner (106) valve stem. The nozzle body (102) forms an outer valve seat (120) located at the distal end (116). The outer valve stem (104) is slidably disposed in the nozzle body (102). The inner valve stem (106) is slidably disposed in the outer valve stem (104). The inner valve stem (106) is in the open position and the outer valve stem (104) is in the closed position when the first pressure is applied to the distal ends (138, 126) of the inner and outer valve stems. And, both the inner and outer valve stems (106, 104) are open when a second pressure, which is greater than the first pressure, is applied to the distal ends of the inner and outer valve stems (106, 104).

EFFECT: invention makes the use of the multicone multistage spray nozzle more effective.
