DEVICE FOR LIQUID SPRAYING Russian patent published in 2003 - IPC

FIELD: hygiene equipment, particularly, shower heads. SUBSTANCE: device has body in which spraying member is installed with exhaust holes whose axes are located at an angle to body axis. External surface of spraying member is cylindrical. Body internal surface conjugated with external surface of spraying member is made with radius of curvature. Body internal surface from end side opposite to exhaust holes has bore in which ring from flexible material is installed. Spraying member is made for axial motion relative to body internal surface. Internal side surface of spraying member is made in the form of surface of revolution. Base of spraying member with exhaust holes has central part and side surfaces located at an angle α=10-20 deg to body axis. Exhaust holes on central and flat side surfaces of base are located over periphery by at least two concentric groups. Motion limiter is made on external surface of spraying member from side of holes. Configuration of body internal surface together with exhaust holes forms jet-forming system. EFFECT: higher operating reliability and durability. 2 cl, 3 dwg
