Beschreibung
Zusammenfassung:	A valve arrangement for a switching valve and to a switching valve for regulating a mass flow in a refrigerating circuit or a heating circuit, including a valve housing, which includes a feed opening and a discharge opening, including a valve piston, which includes a valve-closing member, which buts against a through-hole between the feed opening and the discharge opening in a closed position on a valve seat and closes the through-hole, wherein the valve seat includes a stop surface and a sealing surface which are oriented so as to be adjacent to one another, the valve-closing member includes a supporting surface and a gasket surface which are oriented so as to be adjacent to one another, an elastic sealing element is provided on the valve seat or the valve-closing member, on which sealing element the sealing surface or gasket surface is formed, a sealing projection is provided on the sealing surface or the gasket surface and is oriented towards the opposite gasket surface or sealing surface, the supporting surface of the valve-closing member and the stop surface of the valve seat but against one another in the closed position and form a travel limitation between the valve-closing member and the valve seat, and the sealing projection is at least partially pressed into the sealing element.
