Abstract
(DE) Steuerventil für hydraulische Vorrichtungen, das an einem Bauteil, Insbesondere an einem Bauteil einer Brennkraftmaschine, mittels- einer Flanschverbindung befestigbar ist mit einem ein Ventilgehäuse (4) aufweisenden Hydraulikteil (5), in dem ein Steuerkolben (7) verschiebbar eingebaut Ist, der mittels einer Feder (10, 15) zumindest indirekt belastet und andererseits von einer Elektromagneteinheit (9) beherrscht ist, wobei die Elektromagneteinheit (9) an einem Stützgehäuse (1) fixiert ist wobei die Elektromagneteinheit (9) zwei Spulenelemente (11 und 12) aufweist, die koaxial nebeneinander angeordnet sind, und wobei die Spulenelemenfe (11 und 12) einzeln und/oder gemeinsam elektrisch bestrombar sind.
(EN) Disclosed is a control valve for hydraulic devices, which control valve can be fixed on a component, in particular on a component of an internal combustion engine, by means of a flange connection, comprising a hydraulic part (5), which has a valve housing (4) and in which a control piston (7) is displaceably fitted, which control piston is at least indirectly loaded by a spring (10, 15) and, on the other side, is controlled by an electromagnetic unit (9). The electromagnetic unit (9) is fixed on a support housing (1) and said electromagnetic unit (9) has two coil elements (11 and 12) which are arranged coaxially adjacently, and wherein the coil elements (11 and 12) can be supplied with electric current individually and/or jointly.
(FR) Soupape de commande pour dispositifs hydrauliques, pouvant être fixée à une pièce, notamment à un élément d'un moteur à combustion interne, au moyen d'une bride et comprenant un élément hydraulique (5) pourvu d'une cage de soupape (4), dans lequel un piston de commande (7) est monté coulissant, ce piston étant soumis à la sollicitation au moins indirecte d'un ressort (10, 15) et actionné par une unité électromagnétique (9) qui est fixée à un boîtier support (1). L'unité électromagnétique (9) comporte deux éléments bobines (11 et 12) disposés l'un à côté de l'autre de manière coaxiale, ces éléments bobines (11 et 12) pouvant être traversés par un courant électrique ensemble et/ou individuellement.
