Abstract
The mechanism incorporates at least one assistance unit consisting of a fixed piston (44) supported by a hollow rod (43) and of a cylinder (32) housed in a bore (30) of the rack (11), the chambers (60, 61) being supplied through separate passages (62, 63) extending through the hollow rod (43). The mechanism, advantageously of the type with central output and with a double circuit, incorporates a double circuit distribution valve mechanism (20) for supplying selectively the pairs of chambers (60, 61) on each side of the pinion (12) of the rack (11).
