Abstract
The cooperating double-acting piston/cylinder assistance assembly of the rack (20) incorporates a cylinder (24) firmly fixed to one end of the rack, in the extension of the latter and a stationary piston (40) fixed to one end of a hollow rod (42) whose other end (43) is fixed centrally in the steering casing (10), the hollow rod enclosing two separate fluid passages (45, 47) for supplying the chambers which are in opposition (46, 48), on each side of the piston (40), with actuating fluid under pressure coming from a distribution valve (30) mounted in the casing (10).
