ABSTRACT:
The temperature-dependently controllable fluid friction clutch comprises a temperature-control device for the shear fluid circulation, with a bimetallic element (35) held on an end wall of the housing (7) and coupled, through a pin (39) freely displaceably guided in a bore (37), with a valve (25, 27) of the temperature-control device. To seal the pin (39) in relation to the housing (7) on the part of the pin (39) issuing from the housing (7) there is set a sealing element (41) which rests under axial stress through a sealing flange (43) of substantially annular disc form on a sealing surface (45) extending transversely of the axis (1) of rotation. The sealing flange (43) has substantially the form of a relatively shallow or flat frusto-conical shell widening towards the sealing surface (45) and is stressed substantially only to flex elastically. In this way friction forces between the pin (39) and the bore (37) can be reduced, which improves the accuracy of the temperature control.
