SHOWER JET-FORMING DEVICE WITH EXCESS PRESSURE VALVE Russian patent published in 2019 - IPC B05B1/18 A47K3/28 

FIELD: sanitary equipment.

SUBSTANCE: invention relates to a shower jet-forming device for a shower head, preferably a shower head. Shower shower-forming device for a shower head, preferably a sanitaryware shower head, comprises a shower jet disc limiting the fluid chamber on the outlet side and including at least one jet discharge outlet leading from the fluid chamber, and at least one excess pressure valve hole. Besides, the shower jet-forming device contains at least one excess pressure valve located at the overpressure valve opening. Overpressure valve includes overpressure discharge hole driving from fluid medium chamber, fixed valve seat and valve body, which can be moved under control of fluid medium pressure in fluid medium chamber and interacts with said valve seat. Valve body in the normal pressure position adjoins the valve seat, thus closing the overpressure discharge hole, and in the excess pressure position is spaced from the valve seat, thereby opening the overpressure discharge hole. Valve body is made in the form of a membrane body of a valve made from an elastic material. Valve diaphragm body contains cylindrical central part entering into hole of excess pressure valve, and movable deformable-swinging edge part surrounding central part. Membrane valve body is configured to move with its central part in the opening of the excess pressure valve between the normal pressure position and the excess pressure position due to deforming flap movement of the edge part with the main component of the direction perpendicular to the shower jet disk.

EFFECT: technical result is relatively low manufacturing costs and preferability in terms of implementation of its excess pressure valve.
