Abstract: The invention relates to a fluid friction coupling comprising a drive shaft (2) and a drive disk (4) which is rotationally fixed thereon, in addition to a drive housing (5) which is rotationally arranged on the drive shaft (2). The drive disk forms a working area (7) and a storage area (9) enabling a fluidic connection for a viscous medium via a feed hole (11) and a return channel (8). The feed hole (11) is controlled by a valve lever (12) with an anchor plate (14) by means of an electromagnet (19) arranged on the near side of the coupling. According to the invention, the valve lever (12) is arranged between the drive disk (4) and the electromagnet (19) and the anchor plate (14) is arranged in the magnetic flow area of the electromagnet (19, 20).
