Abstract
The power assisted steering system, particularly of the type with central output, incorporates a body (10) forming a housing for a cooperating pinion (12) and rack (11) assembly. The rack is guided in the central portion (10.sub.1) of the body and is joined by a rod (40) to at least a first piston (30a) movable in a cylinder consisting of a component in the shape of a cylindrical bell (20a, 20b) attached to one end of the body (10) and itself consisting of a rolling membrane (31) joined at its periphery to the component in the shape of a bell, and of a tubular support component (24) fixed to the rod (40) and coaxial with the latter. Also described are variants with a twin circuit incorporating a second piston carried by the rod and sliding so that it is sealed relative to a central stationary component passing longitudinally through the rack.
