ABSTRACT:
A valve arrangement has a valve unit (3) fixed in position via two mutually spaced attachment structures (27and28) on a mounting face (6) of a valve support (2). The first attachment structure (27) includes two mutually engaged hook sections (32and33). The second attachment structure (28) includes a U-like retaining clip (58), which is so able to be attached to the structural unit comprising the valve unit (58) and the valve support (2) that its clamping limbs (63and64) act on clip sections (54and55) and accordingly braces the valve unit (3) onto the valve support (2).
