Abstract
A pressure plate for a clutch cover assembly for an automotive vehicle comprises, on the side opposite that through which it is adapted to operate on a friction disk, axially projecting cooling fins 24. Certain at least of these extend substantially from its inside perimeter to its outside perimeter. Oblique air circulation grooves are defined between them. Over at least part of their length, the air circulation grooves are closed off in the axial direction, on the side opposite the pressure plate, by a separate confinement member which is attached to the pressure plate.
