ABSTRACT:
A housing mounts an input shaft with a clutch flange thereon, and an output shaft with an annular friction member thereon to divide the housing clutch chamber into two separate operating chambers. A brake ring has a first friction face facing the friction lining of the friction member while the friction member has a second friction lining facing the clutch flange. The friction member is axially displaceable a limited amounted by a compressible fluid for controlling the movement of the friction linings axially between the linings and into engagement with one of the brake member and the clutch flange. Each of the clutch flange and the brake ring has an annular groove concentric to the coextensive axes of the shafts that opens to the axially adjacent friction lining. The grooves serve to have granular material of the abradable material of the linings, if the linings are made of such material, accumulated therein and have the ribs of the linings that are formed by the abrasion of the linings extend axially thereinto to form a slight throttle gap.
