Abstract

Es wird eine hydraulische Ventilanordnung (1) angegeben mit einem Hochdruckanschluß (P), einem Niederdruckanschluß (T), einem Lastfühlanschluß (LS) und einem Druckableitventil (12) zwischen dem Hochdruckanschluß (P) und dem Niederdruckanschluß (T). DOLLAR A Man möchte auf möglichst einfache Weise Energie mit Hilfe des Druckableitventils sparen können. DOLLAR A Hierzu ist vorgesehen, daß das Druckableitventil (12) als hydraulisch steuerbares Ventil ausgebildet ist, das einen Steuereingang (13) aufweist, der mit einem durch einen Druck am Lastfühlanschluß (LS) gesteuerten Pilotventil (17) verbunden ist.
