Title
(EN) THROTTLE DEVICE
(FR) DISPOSITIF REGULATEUR
Abstract
(EN)
A throttle device (1) comprises a device housing (15) with an inlet (2) and an outlet (3) and a throttle element (5) arranged in a connecting duct (4) connecting the inlet (2) and the outlet (3), said throttle element comprising at least two throttle components (6, 7) to be adjusted relative to one another and by the relative position of which an opening surface of the throttle element (5) is determined, at least the first throttle component (6) being actively connected with a drive means (8) for an adjustment relative to the second throttle component (7). In order to guarantee with a simplified construction a safe operation of the throttle device without the risk of a choking of the corresponding throttle element and to simultaneously realize a simple possibility of movement for the throttle components, the throttle components are throttling discs to be rotated relative one to another, at least one of which being movably connected with a rotary adjustment device (11) of the drive means (8), the throttling discs (9, 10) each comprising at least one throttle opening (12, 13, 40, 41) the overlap of which determines the opening surface depending on the relative position of the throttling discs (9, 10).
(FR)
L'invention concerne un dispositif (1) régulateur comprenant un corps (15) doté d'une entrée (2) et d'une sortie (3), et un élément d'étranglement (5) disposé dans un conduit (4) de raccordement reliant l'entrée (2) et la sortie (3), ledit élément d'étranglement comprenant au moins deux composants d'étranglement (6, 7) réglables l'un par rapport à l'autre et dont la position relative détermine la surface d'ouverture de l'élément d'étranglement. Au moins le premier composant d'étranglement est relié activement à des moyens de commande (8) qui permettent de le régler relativement au second composant d'étranglement (7). Afin de garantir un fonctionnement sûr de cet élément régulateur, au moyen d'une construction simplifiée, sans risque d'obstruction de l'élément d'étranglement correspondant, tout en permettant aux composants d'étranglement d'être actionnés par un mouvement simple, ces composants d'étranglement sont des disques d'étranglement actionnés par une rotation relative l'un par rapport à l'autre, au moins un de ces disques étant relié de manière mobile à un dispositif (11) de réglage rotatif associé aux moyens de commande (8). Les disques d'étranglement (9, 10) comprennent chacun au moins une ouverture d'étranglement (12, 13, 40, 41) dont le chevauchement détermine la surface d'ouverture en fonction de la position relative des disques (9, 10).
