Abstract
1329044 Friction clutch CONCENTRIC PUMPS Ltd 31 July 1971 36117/71 Heading F2C A cooling fan, having blades 20, for an internal combustion engine is driven when a wax cell thermostat 46 mounted in the water impeller 44 actuates a clutch by means of the rods 48 and 50 within the driving spindle 40 from a pulley 18. As shown the fan has a hub 10 rotatable mounted on a hub 14 which is part of the pulley 18, plates 24 and 26 of the clutch being attached to the pulley and a plate 22 being attached to the fan hub 10, a cross-bar 36 passing through the hub 14 and the shaft 40 moving a presser plate 34 to actuate the clutch when a rod 50 acts against it due to operation of the thermostat. Springs (not shown) serve to separate plate 34 from a backing annulus 32 when the thermostat cools and the rod 48 is withdrawn into it. An alternative embodiment is shown in which a diaphragm spring attached to a movable collar on the hub of the pulley serves to actuate the clutch on engagement of a single rod 50 with an adjustable screw on a member within the collar. The adjustment of the screw adjusts a certain free play in the linkage between the rod 48 and the clutch and so alters the point at which the thermostat (and so the temperature) causes the clutch to engage.
