    摘要： The invention relates to a hydrodynamic clutch comprising an impeller (1) and a turbine wheel (2) which jointly form a toroidal working chamber (3) that is or can be filled with a working medium. A throttle plate (4) is provided which can be moved in the axial direction of the hydrodynamic clutch in order to be optionally introduced into the working chamber and/or be displaced within the working chamber. Said throttle plate extends in the area of a central diameter of the working chamber in the circumferential direction of the hydrodynamic clutch. The intake end of the throttle plate extends parallel or substantially parallel to the axis of rotation of the hydrodynamic clutch from the perspective of an axial section across the hydrodynamic clutch, the working medium flowing against the intake end of the throttle plate in a circular flow. The throttle plate can be moved from an inactive position in which the same has no or only a slight throttling effect on the circular flow of the working medium in the working chamber into an active position in which the same has a comparatively much greater throttling effect on the circular flow, the inactive position being located in the area of the separation gap between the impeller and the turbine wheel. From the perspective of an axial section across the hydrodynamic clutch, the working chamber covers the entire area, without having a center that is delimited relative to the remaining working chamber by means of a wall, such that the throttle plate is directly enclosed by the flow zone of the working chamber in both the active and inactive position of the throttle plate without mounting a wall therebetween.

    摘要： The invention relates to a fluid flow control device (2), in particular a gas flow control valve, having the following: a body (26) with an inlet (23), an outlet (24), and a channel (5) which lies between the inlet and the outlet and through which a fluid flow can be conducted; and a valve unit (8) comprising a control body (3) and a valve seat ring (25) which is coupled to the body (26) and defines a passage that forms a sub-section of the channel (5). The control body (3) engages into the passage and can be moved along an axis (6) between an open position and a closed position in order to control the fluid flow in the passage. According to the invention, the seal system is modified so as to be simpler to assemble and ensure a damage-free operation. For this purpose, a seal system is proposed which is characterized in that the valve unit (8) is designed in at least two parts, wherein a seal element (17) is arranged between the parts (3, 18, 25) of the valve unit (8), and the valve seat ring (25) has a sealing surface (12). The seal element (17) is arranged so as to be movable against the sealing surface (12), which is arranged substantially perpendicular to the axis (6).
