ABSTRACT:
Speed and temperature responsive drive apparatus includes a friction clutch which may be interposed between a vehicle engine and its associated cooling system fan. The clutch is biased toward engagement by a conventional spring and also by a thermal spring. A bladder develops a centrifugal pressure upon rotation of the apparatus, which pressure relieves the biasing forces of both springs.
