Title (DE) VORGESTEUERTES VENTIL UND VENTILGESTEUERTE HYDROMASCHINE
(EN) PILOT-CONTROLLED VALVE AND VALVE-CONTROLLED HYDRAULIC MACHINE
(FR) SOUPAPE PILOTE ET MACHINE HYDRAULIQUE À COMMANDE PAR SOUPAPE
Abstract:
(DE) Offenbart sind ein vorgesteuertes Ventil mit einer elektromagnetisch betätigten Vorsteuerung und eine ventilgesteuerte Hydromaschine mit einem derartigen Ventil. Erfindungsgemäß ist neben einem Anker der elektromagnetisch betätigten Vorsteuerung noch ein weiterer Hauptstufenanker vorgesehen, über den ein Ventilkörper der Hauptstufe zum Öffnen eines Druckmittelströmungspfads in eine Öffnungsstellung bewegbar ist.
(EN) The invention discloses a pilot-controlled valve having an electromagnetically actuated pilot control and a valve-controlled hydraulic machine having such a valve. In addition to an armature of the electromagnetically actuated pilot control, according to the invention a further main stage armature is provided, by way of which a valve body of the main stage can be moved into an open position in order to open a pressure medium flow path.
(FR) L'invention concerne une soupape pilote avec une commande pilote actionnée électromagnétiquement et une machine hydraulique à commande par soupape équipée d'une telle soupape. Selon l'invention, il est prévu à côté d'une armature de la commande pilote actionnée électromagnétiquement une autre armature principale à circuits étagés par l'intermédiaire de laquelle un corps de soupape du circuit principal peut être déplacé dans une position d'ouverture pour ouvrir une voie d'écoulement de fluide sous pression.
