Abstract
The fitting with the hose shower comprises a fitting housing at which there is arranged a laterally actuatable control cartridge. Downstream of the control cartridge, viewed with respect to the direction of water flow, there is provided a safety device arranged above the control cartridge. Under normal operating conditions, water flows from the control cartridge via the safety device to an outlet. Under conditions rendering possible a backflow, a backflow preventer of the safety device cuts off the flow path of water and a pipe aerator connects the outflow line or conduit via an aeration path with the environment. As a result, there is precluded a backflow of water into the supply or feed line.

A sanitary fitting provided for at least one supply line and containing an outflow line leading to an outlet, comprising:
- a fitting housing having lateral ends and a front side;
- a control cartridge arranged in said fitting housing and possessing an inlet side;
- said control cartridge being structured to be actuatable from one of said lateral ends of said fitting housing and connected at said inlet side with the at least one supply line;
- said control cartridge serving to regulate water flowing through the sanitary fitting to the outlet;
- water flowing through the sanitary fitting to the outlet having a predetermined direction of flow;
- a safety device provided in said fitting housing and arranged, viewed with respect to said predetermined direction of flow, downstream of said control cartridge;
- said safety device serving to prevent backflow of water into the at least one supply line;
- said safety device having a ventilation aperture which in the presence of normal water flow is closed and, under conditions rendering possible backflow of water, is open for ventilating at least the outflow line connecting said safety device with the outlet;
