(FR) SOUPAPE DE DISTRIBUTION
Abstract
(DE)
Offenbart ist ein Wegeventil (1) mit einem stirnseitigen Anschluss (A) und zumindest einem Radialanschluss (B), wobei die Stirnflächen eines Ventilkörpers (16) (Ventilschieber oder Sitzkörper) des Wegeventils etwa vom gleichen Druck beaufschlagt sind, so dass die Stellkräfte zum Verschieben des Ventilkörpers minimal sind. Erfindungsgemäss wird der Druck zum Beaufschlagen einer rückwärtigen Stirnfläche (18) des Ventilkörpers im Axialabstand zum Ventilkörper abgegriffen.
(EN)
The invention relates to a directional-control valve (1) comprising a connection (A) on the front face thereof and at least one radial connection (B). The front faces of the valve body (16) (valve sleeve or seat body) of the directional-control valve are impinged by approximately the same pressure, so that the actuating forces for displacing the valve body are minimal. According to the invention, the pressure to be subjected on a rearward front face (18) of the valve body is tapped at an axial distance from the valve body.
(FR)
La présente invention concerne une soupape de distribution (1) comprenant un raccord (A) dans sa partie frontale, et au moins un raccord radial (B), les surfaces frontales d'un corps de soupape (16) (coulisseau de soupape ou corps de siège) de la soupape de distribution étant soumises à une pression approximativement égale, de sorte que les forces de régulation destinées à faire se déplacer le corps de sopupape sont minimales. Selon l'invention, la pression agissant sur un face frontale dirigée vers l'arrière (18), du corps de soupape, est prise à une distance axiale du corps de soupape.
