Abstract

A shower jet generating device for a shower head, illustratively for a sanitary shower head, including a shower jet disk delimiting a fluid chamber on an outlet side and including at least one jet outlet opening leading out of the fluid chamber and at least one overpressure valve opening, and comprising at least one overpressure valve disposed on the overpressure valve opening. The overpressure valve illustratively includes an overpressure outlet opening leading out of the fluid chamber, an immobile valve seat and a valve body capable of movement controlled by a fluid pressure in the fluid chamber and interacting with the valve seat, which valve body, in a normal pressure position, rests against the valve seat, thereby closing the overpressure outlet opening, and, in an overpressure position, is lifted off the valve seat, thereby exposing the overpressure outlet opening.
