Abstract
(DE)
Die Erfindung betrifft ein Ventil (20) mit einem Ventilgehäuse (2), wenigstens einem Kolben (3), mindestens einem Stützelement (4) und zumindest einer Feder (5), mit den Merkmalen: - der Kolben (3) und das Ventilgehäuse (2) sind zueinander koaxial auf einer gedachten Ventilachse (6) angeordnet, wobei die Ventilachse (6) in eine erste axiale Richtung sowie in eine zur ersten axialen Richtung entgegengesetzte zweite axiale Richtung axial ausgerichtet ist, - der Kolben (3) ist gegen Federkräfte der Feder (5) axial beweglich in dem Ventilgehäuse (2) aufgenommen, wobei die Feder (5) zumindest in die erste axiale Richtung an dem Stützelement (4) und in die zweite axiale Richtung an dem Kolben (3) abgestützt ist, - das Stützelement (4) ist an dem Ventilgehäuse (2) abgestützt, - der Kolben (3) weist einen Kolbenboden (7) und einen Kolbenmantel (9) auf, - das Ventilgehäuse (2) ist mit einer strömungsmitteldurchlässigen ersten Öffnung (8) versehen, welche durch den Kolbenboden (7) verschließbar ist, - der Kolben (3) ist über den Kolbenmantel (9) in dem Ventilgehäuse (2) geführt dabei axial gegen die Feder (5) in Richtung des Stützelementes (4) verschiebbar, - das Ventilgehäuse (2) ist an einem axial von der ersten Öffnung (8) entfernten Ende (19) wenigstens eine für die Strömungsmittel durchlässige Drosselöffnung auf, welche durch eine Drosselscheibe (32) begrenzt ist.
(EN)
The invention relates to a valve (20) with a valve housing (2), at least one piston (3), at least one supporting element (4) and at least one spring (5), with the features: - the piston (3) and the valve housing (2) are arranged coaxially with respect to one another on an imaginary valve axis (6), wherein the valve axis (6) is oriented axially in a first axial direction and in a second axial direction which is opposed to the first axial direction, - the piston (3) is received in the valve housing (2) such that it can be moved axially counter to spring forces of the spring (5), wherein the spring (5) is supported on the supporting element (4) at least in the first axial direction and on the piston (3) in the second axial direction, - the supporting element (4) is supported on the valve housing (2), - the piston (3) has a piston crown (7) and a piston skirt (9), - the valve housing (2) is provided with a first opening (8) which is permeable to flow medium and which can be closed by way of the piston crown (7), - the piston (3) can be displaced here axially counter to the spring (5) in the direction of the supporting element (4) in a manner which is guided in the valve housing (2) via the piston skirt (9), - the valve housing (2) has, at an end (19) which is axially remote from the first opening (8), at least one throttle opening which is permeable for the flow medium and which is delimited by way of a throttle plate (32).
(FR)
L’invention concerne une soupape (20) comportant un carter (2) de soupape, au moins un piston (3), au moins un élément d’appui (4) et au moins un ressort (5), et présentant les caractéristiques suivantes : - le piston (3) et le carter (2) de soupape sont agencés coaxialement l’un par rapport à l’autre sur un axe (6) imaginaire de la soupape, l’axe (6) de la soupape étant orienté axialement dans une première direction axiale ainsi que dans une seconde direction axiale opposée à la première direction axiale, - le piston (3) est logé dans le carter (2) de soupape mobile axialement à l’encontre des forces du ressort (5), le ressort (5) prenant appui au moins dans la première direction axiale sur l’élément d’appui (4) et dans la seconde direction axiale sur le piston (3), - l’élément d’appui (4) prend appui sur le carter (2) de soupape, - le piston (3) présente un fond (7) de piston et une jupe (9) de piston, - le carter (2) de soupape est muni d’une première ouverture (8) laissant passer le fluide, qui peut être fermée par le fond (7) de piston, - le piston (3) peut être déplacé dans le carter (2) de soupape par la jupe (9) de piston axialement par rapport au ressort (5) en direction de l’élément d’appui (4), - le carter (2) de soupape présente à une extrémité (19) éloignée axialement de la première ouverture (8) au moins une ouverture d’étranglement laissant passer le fluide, qui est délimitée par un disque d’étranglement (32).
