ABSTRACT:
In a rotating hydraulic distributor of the type comprising two axially adjacent rotating members (20, 23) arranged for relative rotation one with respect to the other over a limited angular range, both said rotating members having cooperating closing edges (30, 31) defining therebetween a modulable fluid flow passage, at least one of said edges (30) presents a chamfer having an evolutive profile with non-parallel generatrices whereby, for each relative angular offsetting between both said rotating members, the fluid flow passsage (S.sub.2) between said cooperating edges has an identical width over the length extension, substantially in the radial direction, of the passage.
