Is represented by the German utility model. A central connection 12 can be seen there, 1725 051 a bath heater has become known, at 50 in the upper part of which a recess 13 is formed, a ventilation valve is det at the upper apex. This recess also has a cross-section of a curved pipe section, the running groove 14 (see FIG. 2).
as an extension of the riser pipe of this bathing heater in front of a rubber plate is loosely in the recess as is seen. This curved pipe section is placed on sealing washer 15, the diameter of which is smaller, and ends in the shower hose. The shower head 55 than that of the recess 13, and the height of which can also be headed just below the ventilation valve, is smaller than that of the recess,
a bracket can be attached. A disk 16 is provided over the sealing disk 15

Starting from a ventilation valve, a central opening 17 is placed. This disc is in the type mentioned, the invention is the task F i g. 3 shown as a single part. The disk 16 is based on the design of this ventilation valve in such a way that 60 a recess 20 is glued in as a sealing seat, which is arranged above the recess 13 to increase the service life and operational reliability.

This object is achieved according to the invention in such a way that the air is achieved through the central opening 17 and on, daP. The sealing washer is sucked in a recess of the sealing washer 15 through the groove 14 in the arrow valve housing with a transverse groove in the direction 18. If the opposite is true in the line body. if there is overpressure by 8, the sealing

The sealing disk thus lies loosely in the recess disk 15 on the disk 16 and thus closes the mung, so that it can also with a possible aging central opening 17.
