ABSTRACT:
A viscous fluid clutch for driving a cooling fan 18 from the crankshaft of an internal combustion engine includes an outer rotary casing 11, 12 connected to the fan and an inner rotary member 10 connected to the crankshaft coupling 9. The clearance gap between these two members is normally occupied by a viscous fluid and the drive is automatically adjusted by varying the quantity of fluid in the gap. A scoop pump 22 continuously pumps fluid from the gap inwards along passage 24 to a reservoir 20 via control valve 50, and the fluid returns to the clearance gap from the reservoir via a port 26. The valve 50 includes a piston 61, which is subject on one side of the pressure of the fluid supplied by the scoop pump 22, and hence to the relative speed of rotation between the crankshaft and the fan. In the other direction the piston 61 is subject to the fluid servo pressure in a conduit 48 derived from the sensed temperature of the engine coolant in duct 40.
