Abstract
The fitting has in each case a hydraulically operable shutoff valve (40, 42) for hot and cold water. The diaphragm-shaped closure part (56) interacts with the valve seat (52). Provided on the side opposite the valve seat (52) is a pilot control space (60) which is connected through the passage (62) to the annular channel (48) and the corresponding feedline (20). Via control lines (86'"'"'), each pilot control space (60) is connected to the outlet line (24) via an auxiliary valve (70'"'"'). The two auxiliary valves (70'"'"') are constructed on a ceramic disk valve (72) and can be operated jointly. When the auxiliary valves (70, 70'"'"') are closed, the pressure in the pilot control space (60) corresponds to the pressure in the annular channel (48), the shutoff valves (40, 42) are closed. By rotating the operating shaft (86) the two auxiliary valves (70'"'"') are opened, by which means the pressure in the pilot control spaces (60) drops. The closure part (56) is lifted from the relevant valve seat (52) and the shutoff valves (40, 42) are opened. When the auxiliary valves (70'"'"') are closed by rotating the operating shaft (86), the pressure in the pilot control spaces (60) rises again, by which means the shutoff valves (40, 42) are closed. The joint operation of both shutoff valves (70, 70'"'"') requires extremely little energy.
