Abstract

1377477 Clutch control; viscous couplings DYNAIR Ltd 17 Nov 1971 [21 Nov 1970] 31126/74 Divided out of 1377476 Heading F2C A drive to a fan 75 of an internal combustion engine is through a viscous fluid coupling comprising an input member 62 rotated in a chamber of a driven housing 63, between a wall of the housing and a partition plate 65 fixed to the housing, this plate 65 having apertures in it through which scoops 70 can move to remove some or all of the working fluid from the chamber containing driving member 62, the scoops being attached to a member 71, axially movable in dependence on the temperature of the engine coolant. The scoops 70, shown in detail in Fig. 3, transfer the working fluid from the working chamber to a reservoir 67 on the opposite side of partition 65. The movement of member 71 and scoops 70 is by a piston 83 movable under air pressure supplied through a pipe 80 and acting on member 71 through a thrust bearing 84 and a cap 85, the air supply being controlled by a valve responsive to the coolant temperature. Tangential springs 87 return the member 71 and withdraw the scoops 70 on release of pressure.
