Title
(DE) SCHALTVENTIL ZUM STEUERN EINER GASSTRÖMUNG
(EN) CONTROL VALVE FOR CONTROLLING A GAS FLOW
(FR) SOUPAPE DE COMMANDE POUR COMMANDER UN ÉCOULEMENT DE GAZ
Abstract
(DE)
Die vorliegende Erfindung betrifft ein Schaltventil (1) zum Steuern einer Gasströmung in einer Gasleitung (3) einer Brennkraftmaschine, insbesondere in einem Kraftfahrzeug, umfassend eine drehverstellbare Klappe (4) zum Steuern eines Strömungsquerschnitts (13), einen Drosseldichtspalt (14), der in einer Schließstellung der Klappe (4) radial zwischen einer Dichtkontur (15) der Klappe (4) und einer der Klappe (4) zugewandten Dichtfläche (16) ausgebildet ist, und eine Antriebswelle (5), an der die Klappe (4) drehfest angeordnet ist. Um die Justierung des Drosseldichtspalts (14) zu vereinfachen, ist ein Leitungsstück (2) zum Einbau in die Gasleitung (3) axial zwischen Leitungsenden (9) vorgesehen, wobei die Klappe (4) den Strömungsquerschnitt (13) des Leitungsstücks (2) steuert, wobei die Dichtfläche (16) am Leitungsstück (2) ausgebildet ist, wobei die Antriebswelle (5) das Leitungsstück (2) durchsetzt und in zwei Lagern (18) gelagert ist, wobei zwei Lagerschalen (19) vorgesehen sind, die außen am Leitungsstück (2) angeordnet sind und die jeweils eines der Lager (18) aufweisen.
(EN)
The present invention relates to a control valve (1) for controlling a gas flow in a gas line (3) of an internal combustion engine, in particular in a motor vehicle, comprising a rotationally adjustable flap (4) for controlling a flow cross section (13), a throttling sealing gap (14) which, in a closed position of the flap (4), is formed radially between a sealing contour (15) of the flap (4) and a sealing face (16) which faces the flap (4), and a drive shaft (5), on which the flap (4) is arranged fixedly in terms of rotation. In order to simplify the adjustment of the throttling sealing gap (14), a line piece (2) is provided for installation in the gas line (3) axially between line ends (9), wherein the flap (4) controls the flow cross section (13) of the line piece (2), wherein the sealing face (16) is formed on the line piece (2), wherein the drive shaft (5) penetrates the line piece (2) and is mounted in two bearings (18), wherein two bearing shells (19) are provided which are arranged on the outside of the line piece (2) and in each case have one of the bearings (18).
(FR)
L'invention concerne une soupape de commande (1) pour commander un écoulement de gaz dans une conduite de gaz (3) d'un moteur à combustion interne, notamment dans un véhicule automobile. Elle comprend un clapet (4) réglable par rotation pour commander une section d'écoulement (13), une fente d'étanchéité d'étranglement (14) qui est formée dans une position fermée du clapet (4) entre un contour d'étanchéité (15) du clapet (4) et une surface d'étanchéité (16) tournée vers le clapet (4), et un arbre d'entraînement (5) sur lequel le clapet (4) est disposé en solidarité de rotation. Afin de simplifier l'ajustement de la fente d'étanchéité d'étranglement (14), il est prévu un tronçon de conduite (2) à installer dans la conduite de gaz (3) axialement entre des extrémités de conduite (9). Le clapet (4) commande la section d'écoulement (13) dans le tronçon de conduite (2), la surface d'étanchéité (16) étant formée sur le tronçon de conduite (2). L'arbre d'entraînement (5) traverse le tronçon de conduite (2) et est monté dans deux coussinets (18), deux coquilles de coussinet (19) étant prévues et étant disposées extérieurement sur le tronçon de conduite (2) et présentant chacune un des coussinets (18).
