METHOD OF NOZZLE OPERATION INSTALLED ON TAP OR MIXER FOR WATER SUPPLY Russian patent published in 2019 - IPC E03C1/04 F16K21/04 

FIELD: sanitation equipment.

SUBSTANCE: invention relates to sanitary devices. Method consists in application of user's hand vertical force to rigidly fixed nipple (16) rod-pusher (15), thereby causing its vertical movement upwards with subsequent action end of shank (17) rod-pusher (15) on ball-valve (20) and its separation from sealing gasket (11), as a result, valve seat is opened in the form of insert hole (7) and water is provided to lower volume (22) of nozzle housing (1). By displacement of contact surface of end surface of shank (17) with ball-valve (20) radially away from vertical axis of symmetry additional torque is created, which provides tilting of ball-valve (20) to side with subsequent opening of valve seat in form of hole for free passage of water. After termination of user's hand impact on rigidly fixed nipple (16) of rod-pusher (15), ball-valve (20) as a result of rolling under action of gravity rushes along walls of internal cone (8) into seat of valve in form of hole.

EFFECT: reduced force to open water supply by user's hand.
