<p>The distributor comprises a primary member, a secondary member coaxial with the primary member and having a part (3') at least partially surrounding a part (2') of the primary member, a distribution valve coupled to the primary member, and at least one deformable resilient device (4) having at least one pair of abutment surfaces (5) cooperating with the first (20) and second connection members connected to the primary and secondary members in order to hold them in a relative centered position of rest, the resilient device (4) being mounted so as to be sealingly slidable by opposite annular side faces in an annular cavity (32) formed in a member rotationally fixed to the secondary member and shaped to define in that cavity an internal chamber (6) and an external chamber (7), which are separate and whose volumes are inversely variable, means (8) being provided to direct a fluid under modulable pressure into at least one of these chambers.</p> |
