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). |
