ABSTRACT:
A distribution and shut-off device for hydraulic systems, particularly domestic water systems, comprises at least one main pipe section, an auxiliary pipe having an axis which is not coplanar with the axis of the main pipe section and leading at its ends to two distribution outlets, a passage which connects the main pipe section to the auxiliary pipe, and two valves for shutting off the flow of fluid towards the two distribution outlets. The first on-off valve is situated at the junction of the connecting passage with the auxiliary pipe. The valve is movable between an open position in which the two branches of the auxiliary pipe situated on the two sides of the valve communicate with each other and with the connection passage, and a closed position in which the connection between the two branches of the auxilary pipe is closed and the passage only communicates with the branch of the auxiliary pipe leading to the outlet with which the second on-off valve is associated.
