Abstract

Steering mechanism assisted by motive power for a motor vehicle, which includes a cylinder, a double-acting piston slidable in the cylinder and connectable to a steering column, a control valve to direct fluid under pressure to one side or the other of the double-acting piston in order to provide motor assistance, an opening in the cylinder disposed at each end of the limit of movement of the piston in the cylinder, said cylinder openings being connectable through said control valve, one of them with a source of fluid under pressure and the other with a fluid reservoir, and pressure relief means communicating with each said opening of the cylinder, so that, when the piston is at the end of its movement in one or the other direction, the fluid at high pressure on one side of the piston can pass through said pressure relief means, characterized in that these discharge means of the pressure the invention comprises steps (11, 12) in the wall of the cylinder (6), so that communication can be established between the cylinder (6) on one side of the piston (5) and the cylinder on the other side of such a piston, when it is at the end of its route, as stated.
