Abstract

Offenbart ist eine hydraulische Pilotventilanordnung zur Vorsteuerung eines Ventils (6,306,506), die zumindest ein elektromagnetisch pulsweitenmoduliert betätigbares Pilotventil (34,234,434) aufweist, Das Pilotventil ist dabei ballistisch oder invers ballistisch betätigbar. Weiterhin offenbart ist eine hydraulische Ventilanordnung mit der Pilotventilanordnung (2,102,202,302,402,602) und mit einem Ventil, das über die Pilotventilanordnung vorsteuerbar ist.
