Abstract

Bei einem hydraulisch betätigten Mehrwege-Ventil mit Schwimmstellung zur Verbindung der Zylinderräume (5, 6) eines hydraulischen Kolben-Zylinder-Antriebes (1) ist ein Ventilschieber (12) und ein diesem zugeordne­ ter Gegenhaltekolben (30) vorgesehen. Durch eine ent­ sprechende Bemaßung der Fläche des für die Schwimm­ stellung mit Steuerdruck beaufschlagbaren Teils des Ventilschiebers (12) einerseits und des Gegenhalte­ kolbens (30) andererseits ist eine Verschiebung des Gegenhaltekolbens (30) gegen den in seiner Steuer­ kammer (46) befindlichen maximalen Steuerdruck mög­ lich.
