ABSTRACT:
The present invention proposes a water supply elbow with a plastic housing, suitable for connections with flexible plastic conductors of hydraulic installations of water supply networks and of central heating and air-conditioning networks with the conventional water taps, radiator valves and other commercially available accessories, where mainly built into the walls and/or laid underneath the floor the abovementioned flexible plastic conductors are covered by an external spiral coating. The basic charactertistics of the proposed water supply elbow with a plastic housing are its manufacturing three or more parts which allow for passing through the end cylindrical portion (3) of spiral coverings of the flexible plastic conductors of varying diameters, the simple and economical construction of the generally semicylindrical basement (1) and the generally semicylindrical covering (2) which is mutually engaged by mere contact, the bottom end provided with an internal recession suitable for fitting the third cylindrical part (3) of the housing via tightening through screwing within the holes (18a,b,c) provided onto side flanges (19a,b,c) either of the two parts (1) and (2) or of all three parts (1), (2) and (3) of the housing.
