FLUID MEDIUM DISCHARGE HEAD Russian patent published in 2017 - IPC B05B11/00 

FIELD: machine building.

SUBSTANCE: invention relates to fluid medium release head and can be used in various engineering fields. Fluid medium discharge head has outlet nozzle (5) with outlet opening (6), wherein inner sleeve (7) is located. Inner sleeve has channel (8) for medium and accommodates spring-loaded valve element (10), automatically closing outlet opening (6) by pressure spring (20). Valve element (10) is made in form of cylindrical piston, which is moved along axis in cylindrical chamber (12) formed by inner sleeve (7). For piston ends (16, 17) provision is made for upper (14) and lower (15) valve seats. Valve element (10) has intermediate valve plate (18), which forms pressure chamber (19) bottom attached tor medium channel (8). In discharge chamber (19) medium outlet pressure is created for upper valve seat (14) opening. Opening characteristic is determined by means of cylindrical chamber opening (12) and introducing medium opening in valve lower seat (15) area diameters gear ratio. Gear ratio value is more than 2. Selection of pressure spring (20) stiffness sets medium outlet pressure in discharge chamber (19). Piston upper end (16) has outer sealing edge, through which piston upper end (16) is introduced into valve upper seat (14). Between valve element (10) upper end and outlet nozzle (5) end (13) chamber is formed, which is swirling chamber.

EFFECT: technical result is enabling possibility of action on spray shape and identical suitability for use of different media.
