Drain Fitting For A Floor Drainage Gully And Floor Drainage Gully Having Such A Drain Fitting

Abstract: The invention relates to a drain fitting for a floor drainage gully comprising a housing (3) which can be fixed to a drainage opening (2.4) of the floor drainage gully which housing is formed from a pot like housing lower part (3.1) and a cover like housing upper part (3.2) wherein the housing upper part has an inlet opening (3.21) and the housing lower part has an outlet opening (3.11) wherein the inlet opening (3.21) is surrounded by an annular seal (4) wherein the housing (3) has arranged therein an odour trap which has a separately manufactured cup or bowl shaped container (9) and an immersion tube (10) projecting into the container and wherein the immersion tube (10) is held removably on the inlet opening (3.21) of the housing. In order to ensure that such a drain fitting has a reliable odour trap allows a high drainage capacity and can be implemented with compact circumferential dimensions so that in combination with the floor drainage gully a small overall height is obtained as a whole the invention provides that a pocket like protuberance (3.34) is formed into the housing upper part (3.2) which protuberance is arranged outside the seal (4) surrounding the inlet opening (3.21) and projects upwardly beyond the upper edge (3.211) of the inlet opening (3.21) wherein the protuberance (3.34) and an upper edge (9.7) of the cup or bowl shaped container (9) define an overflow duct of which part extends above the upper edge (3.211) of the inlet opening (3.21).
