Abstract
(DE) Ventil (1) für einen Fluidstrom in einem Fahrzeug mit einem Gehäuse (2), mit wenigstens einer ersten und einer zweiten Anschlussöffnung (10, 11), die in einen Ventilraum (3) des Gehäuses (2) münden, wobei im Ventilraum (3) ein Ventilelement (4) drehbar um eine Drehachse (5) gelagert ist, wobei an einer Außenfläche (8) des Ventilelements (4) zwei voneinander beabstandete Durchgangsöffnungen (13, 14) vorgesehen sind, die durch eine Durchgangsbohrung (12) miteinander verbunden sind, wobei in der Außenfläche (8) des Ventilelements (4) wenigstens eine Ausnehmung (15, 16, 22) eingebracht ist, wobei ein Antriebselement (6) vorgesehen ist, mit dem das Ventilelement (4) um die Drehachse (5) drehbar ist, dadurch gekennzeichnet, dass die wenigstens eine Ausnehmung (15, 16, 22) des Ventilelements (4) getrennt von den Durchgangsöffnungen (13, 14) und der Durchgangsbohrung (12) in der Außenfläche (8) des Ventilkörpers (4) ausgebildet ist, dass um die erste und die zweite Anschlussöffnung (10, 11) ein ringförmiger Dichtsitz (71,72) zwischen dem Gehäuse (2) und dem Ventilelement (4) angeordnet ist, wobei ein Dichtsitz (71, 72) die Anschlussöffnung (10, 11) gegenüber einem Zwischenraum (21), der zwischen dem Gehäuse (2) und dem Ventilelement (4) ausgebildet ist, abdichtet, dass die wenigstens erste Anschlussöffnung (10), die erste Durchgangsbohrung (13) und die wenigstens eine Ausnehmung (15, 16, 22) in einem Bereich in Bezug auf die Drehachse (5) so angeordnet sind, so dass abhängig von der Drehposition des Ventilelementes (4) eine Überdeckung zwischen der ersten Anschlussöffnung (10) und der Ausnehmung (15, 16, 22) und dem Zwischenraum (21) einstellbar ist, wobei zudem die erste Durchgangsbohrung (13) eine Überdeckung mit dem Zwischenraum (21) aufweist.
(EN) The invention relates to a valve (1) for a fluid flow in a vehicle having a housing (2), comprising at least one first and one second connection opening (10, 11) which open into a valve chamber (3) of the housing (2), a valve element (4) being mounted rotatably about a rotational axis (5) in the valve chamber (3), two mutually spaced through-openings (13, 14) being provided on an outer surface (8) of the valve element (4), which through-openings are connected to each other by a through-bore (12), at least one recess (15, 16, 22) being introduced in the outer surface (8) of the valve element (4), a drive element (6) being provided by means of which the valve element (4) is rotatable about the rotational axis (5), characterized in that the at least one recess (15, 16, 22) of the valve element (4) is formed, separately from the through-openings (13, 14) and the through-bore (12), in the outer surface (8) of the valve body (4), that an annular seal seat (71, 72) is arranged around the first and the second connection opening (10, 11), between the housing (2) and the valve element (4), wherein a seal seat (71, 72) seals off the connection opening (10, 11) from an intermediate chamber (21) which is formed between the housing (2) and the valve element (4), that at least the first connection opening (10), the first through-bore (13) and the at least one recess (15, 16, 22) are arranged in a region in relation to the rotational axis (5) such that, depending on the rotation position of the valve element (4), an overlap between the first connection opening (10) and the recess (15, 16, 22) and the intermediate chamber (21) is adjustable, wherein the first through-bore (13) additionally overlaps the intermediate chamber (21).
(FR) L'invention concerne une soupape (1) conçue pour un flux de fluide dans un véhicule, comprenant un carter (2) qui comporte au moins une première et une deuxième ouverture de raccordement (10, 11) qui débouchent dans une chambre de soupape (3) du carter (2), un élément de soupape (4) étant monté rotatif autour d'un axe de rotation (5) dans la chambre de soupape (3), deux ouvertures de passage (13, 14) espacées l'une de l'autre étant prévues sur une surface extérieure (8) de l'élément de soupape (4) et reliées l'une à l'autre par l'intermédiaire d'un orifice de passage (12), au moins un évidement (15, 16, 22) étant présent dans la surface extérieure (8) de l'élément de soupape (4), un élément d'entraînement (6) étant prévu pour permettre à l'élément de soupape (4) de tourner autour de l'axe de rotation (5). Cette invention est caractérisée en ce que l'évidement ou les évidements (15, 16, 22) de l'élément de soupape (4) est/sont formé(s) séparément des ouvertures de passage (13, 14) et de l'orifice de passage (12) dans la surface extérieure (8) du corps de soupape (4), en ce qu'un siège d'étanchéité (71,72) annulaire est disposé autour de la première et deuxième ouverture de raccordement (10, 11) entre le carter (2) et l'élément de soupape (4), un siège d'étanchéité (71, 72) assurant l'étanchéité de l'ouverture de raccordement (10, 11) par rapport à une chambre intermédiaire (21) qui est formée entre le carter (2) et l'élément de soupape (4), en ce qu'au moins la première ouverture de raccordement (10), la première ouverture de passage (13) et l'évidement ou les évidements (15, 16, 22) sont disposés dans une zone par rapport à l'axe de rotation (5) de manière que, en fonction de la position de rotation de l'élément de soupape (4), un chevauchement entre la première ouverture de raccordement (10) et l'évidement (15, 16, 22) et la chambre intermédiaire (21) puisse être réglé, la première ouverture de passage (13) chevauchant en outre la chambre intermédiaire (21).
