Abstract
A sanitary fitting (1) formed from a multi-wall housing (2) which can be inserted into a sanitary water pipe is provided that has at least two adjacent walls (6,7) surrounding an inner region (8). The fitting includes a checj valve , and one wall of the housing (2) is a tubular wall (7) formed of a flexible and/or elastic material. In order to relieve pressure when the check valve is closed and the fluid volume is sealed in on the outflow side, the housing wall (7) can be moved towards the adjacent housing wall (6), compressing the at least one inner region (8), or can be spaced apart from the adjacent housing wall (6) or moved away from same, enlarging the at least one inner region (8).

Sanitary fitting (1) constructed as a check valve comprising a housing (2), including multiple walls, which (2) can be inserted in a sanitary water pipe having at least two mutually adjacent housing walls (6, 7) which enclose an inner region (8) therebetween, one of the housing walls (7) of the housing (2) is formed of a flexible and/or elastic material and is tubular in form, the elastic housing wall (7) can be brought or moved to a spacing from the adjacent housing wall (6), for pressure equalization with the check valve (1) in a closed state and a fluid volume shut off downstream with compression of the at least one inner region (8) against the adjacent housing wall (6) or with expansion of the at least one inner region (8), whereby an outer one of the housing walls (7) is formed of the flexible and/or elastic material, and the elastic housing wall (7) is movable by a fluid volume acting on the elastic housing wall (7) from outside and compressing the inner region, or by a fluid volume flowing into the inner region through at least one passage channel or at least one passage opening (20), with expansion of the inner region (8).
