Beschreibung
Zusammenfassung:	The invention relates to a closing body ( 3 ) which is mounted in a housing ( 2 ) in such a way that it can be axially displaced and can be pressed out of an opening position against a valve seat ( 4 ) into a closing position. Said closing body ( 3 ) is rotationally symmetrical and comprises, on its outer diameter (D 1 ) in relation to its cross-section, two outer wall sections ( 5, 5 ') which meet at an angle of less than 180°. In this way, a surrounding interference edge ( 26 ) is formed, favouring turbulence in the flow and thus a rapid increase in the dynamic pressure. When the closing body is embodied as a hollow body, a spring action also occurs, damping the closing movement.
