ABSTRACT:
A variable speed drive pulley comprises a hub and two annular flange plates around the hub in face-to-face relationship. One of the flange plates is mobile axially relative to the hub. An annular diaphragm of variable cone angle has a peripheral part forming a Belleville spring washer and a central part divided into radial fingers. The Belleville spring washer bears axially on the mobile flange plate through a connection piece and an elastic material annular spacer to which the connection piece is attached. The radial fingers bear on a support piece fixed axially with respect to the hub. A fluid-tight regulating chamber is formed between the mobile flange plate, the diaphragm, the support piece and the hub. It is adapted to be connected to a source of fluid. Sealing means in one piece with the elastic material space are disposed between the connection piece and the mobile flange plate.
