Title
(DE) DRUCKREGELVENTIL
(EN) PRESSURE CONTROL VALVE
(FR) SOUPAPE DE RÉGULATION DE PRESSION
Abstract
(DE)
Druckregelventil mit einem Gehäuse (2), das einen Referenzdruckanschluss (3) und eine Referenzdruckkamer (4). einen Vordrυckanschluss (5) und eine Vordruckkamer (6) sowie einen Regeldruckanschlυss (7) und eine Regeldruckkamer (8) aufweist, die mit einem in dem Gehäuse (2) in Axialrichtung bewegbaren Steuerglied (9) derart zusammenwirken, dass ein gewünschter Regeldruck zwischen einem Vordruck, der am Vordruckanschluss (5) anliegt und einem Referenzdruck, der am Referenzdruckanschluss (7) anliegt, einstellbar ist, wobei eine Antriebsvorrichtung (10) vorgesehen ist, die auf das Steuerglied (9) wirkt wobei mindestens eine erste Dichteinrichtung (11) vorgesehen ist, die die Referenzdruckkamer (8) gegenüber dem Steuerglied (9) abdichtet, wobei mindestens eine zweite Dichteinrichtung (12) vorgesehen ist, die die Vordruckkammer (6) gegenüber der Referenzdruckkammer (7) abdichtet und wobei mindestens eine dritte Dichteinrichtung (13) vorgesehen ist, die die Regeldruckkammer (7) gegenüber der Vordruckkamer (6) abdichtet, wobei die zweite Dichteinrichtung (12) ein zweites Dichtorgan (15) aufweist, das in dem Gehäuse (2) und/oder im Steuerglied (9) formschlüssig angeordnet ist, jedoch in Radialrichtung von dem Steuerglied (9) beabstandet ist.

(EN)
Disclosed is a pressure control valve comprising a housing (2) that has a reference pressure connection (3) and a reference pressure chamber (4), a preliminary pressure connection (5) and a preliminary pressure chamber (6), and a control pressure connection (7) and a control pressure chamber (8) which cooperate with a control member (9) that can be moved in the axial direction within the housing (2) in such a way that a desired control pressure can be adjusted between a preliminary pressure at the preliminary pressure connection (5) and a reference pressure at the reference pressure connection (7). A driving device (10) is provided which acts on the control member (9), at least one first sealing device (11) is provided which seals the reference pressure chamber (8) against the control member (9), at least one second sealing device (12) is provided which seals the preliminary pressure chamber (6) against the reference pressure chamber (7), and at least one third sealing device (13) is provided which seals the control pressure chamber (7) against the preliminary pressure chamber (6). The second sealing device (12) includes a second sealing element (15) that is positively arranged within the housing (2) and/or within the control member (9) while being disposed at a distance from the control member (9) in the radial direction.

(FR)
L'invention concerne une soupape de régulation de pression comprenant un boîtier (2), qui comporte une prise de pression de référence (3) et une chambre de pression de référence (4), une prise de pression d'alimentation (5) et une chambre de pression d'alimentation (6) ainsi qu'une prise de pression de régulation (7) et une chambre de pression de régulation (8), coopérant avec un organe de commande (9) mobile dans la direction axiale à l'intérieur du boîtier (2), de manière à pouvoir régler une pression de régulation souhaitée entre une pression d'alimentation établie à la prise de pression d'alimentation (5) et une pression de référence établie à la prise de pression de référence (7). Un dispositif d'entraînement (10) agit sur l'organe de commande (9). Au moins un premier dispositif d'étanchéité (11) préserve l'étanchéité de la chambre de pression de référence (8) par rapport à l'organe de commande (9), au moins un deuxième dispositif d'étanchéité (12) préserve l'étanchéité de la chambre de pression d'alimentation (6) par rapport à la chambre de pression de référence (7), et au moins un troisième dispositif d'étanchéité (13) préserve l'étanchéité de la chambre de pression de régulation (7) par rapport à la chambre de pression d'alimentation (6). Le deuxième dispositif d'étanchéité (12) comporte un deuxième organe d'étanchéité (15) qui est placé dans le boîtier (2) et/ou dans l'organe de commande (9) par complémentarité de forme, cependant séparé de l'organe de commande (9) dans la direction radiale.
