ABSTRACT:
Friction shoes are placed end-to-end to define a closed shape around a sector on a disc-type matrix and located in a groove cut into a support having two groove walls that cooperate to define the groove therebetween. Each of the friction shoes is biased toward one of the groove walls by a springy plate to effect a seal contact with the one groove wall. A bellows is located on a housing enclosing the matrix and the support.
