Abstract

A poppet valve configured comprising a valve housing with line connections and a valve seat formed therebetween in the valve housing, and a closing element, which is axially displaceable in the valve housing and which cooperates with the valve seat, and a membrane extending around the closing element and from the latter up to a fixing site on the housing side. Due to the fact that a spring-elastic and in particular annular element is additionally provided for fixing the membrane under preload on the housing side, and due to the fact that the spring-elastic element is subdivided towards the sealing fixing site into partially circumferential segments having formed thereon extensions, which press the membrane against the cylindrical fixing site and, in so doing, deform the membrane.
