Abstract
(DE)
In einem Dämpfungsventil (26) für druckmittelbetätigte Arbeitskreisläufe ist ein Federelement (27) zwischen Gehäuse (28), Deckel (29) und Gegenkontur (30) eingebaut. Das Federelement (27) wird durch das durchfließende Druckmittel in Öffnungsrichtung gegen die Gegenkontur (30) gedrückt, so daß sich ein Durchflußquerschnitt einstellt, der einen nahezu unbehinderten Durchfluß des Druckmittels ermöglicht. In Gegenrichtung der Drosselrichtung legt sich das Federelement (27) an dem Deckel (29) an und sperrt den Durchfluß des Druckmittels so lange, bis sich ein definierter Druck aufgebaut hat, der das Federelement (27) an dessen Innenseite von der Gegenkontur (30) abhebt und so einen verringerten Durchflußquerschnitt freigibt.
(EN)
The invention relates to a steam valve (26) for pressure medium-actuated working circuits in which a spring element (27) is installed between the housing (28), cover (29) and countercontour (30). The pressure medium which is flowing through compresses the spring element (27) against the countercontour (30) in the direction of the opening so that a flow-through cross section is adjusted which enables the pressure medium to flow through in an almost unimpeded manner. In a direction counter to the throttling direction, the spring element (27) rests on the cover (29) and blocks the pressure medium from flowing through until a defined pressure has built up which lifts the spring element (27) on the inner side thereof from the countercontour (30) thus releasing a reduced flow-through cross section.
(FR)
l'invention concerne une soupape d'amortissement (26) pour des circuits d'utilisation actionnés par milieu sous pression. Il est prévu dans cette soupape d'amortissement un élément à effet ressort (27), monté entre le boîtier (28), le couvercle (29) et un contour antagoniste (30). L'élément à effet ressort (27) est comprimé dans le sens d'ouverture par un milieu sous pression en écoulement, contre le contour antagoniste (30), de manière qu'une section transversale d'écoulement s'ajuste et permette un écoulement pratiquement libre du milieu sous pression. Dans le sens opposé au sens d'étranglement, l'élément à effet ressort (27) s'applique contre le couvercle (29) et bloque l'écoulement du milieu sous pression jusqu'à ce qu'il règne une pression définie qui soulève ledit élément à effet ressort (27) du contour antagoniste (30) au niveau de sa face intérieure, libérant ainsi une section transversale d'écoulement réduite.
