Abstract
A hydraulic distributor device comprises two members movable relative to one another, either in rotary or translational movement, along a planar sliding interface, at least one narrow groove being provided superficially in one of the members along the interface, so as to minimize or eliminate the axial thrust generated by the fluid pressure. The distributor device may be used in power-assisted steering apparatus for a vehicle.
