Device for connecting e.g. water supply pipe to reservoir of water supply installation, has elastically deformable joint connecting crown gear to base element in sealed and non-rigid manner by closing annular displacement interval

摘要

The device (1) has a base element (2) i.e. plate, including a circular orifice (21) for receiving a pipe (10). A crown gear (3) includes a peripheral surface (34) having diameter less than the section of the orifice and forming an annular displacement interval with the base element. An elastically deformable joint (5) in the form of a ring has an exterior edge (53) fitted in an edge of the orifice, an interior edge (51) fitted in the peripheral surface, and an intermediate part (52). The joint connects the gear to the base element in a sealed and non-rigid manner by closing the interval.
