ABSTRACT:
A hydrostatic servomechanism adapted to control the direction of vehicles and self-propelled machines. The mechanism has a power circuit with at least one servopump, at least one servomotor and at least one distributor, a control circuit with a measuring pump actuated by a command element as for example a steering wheel connected by means of control conduit branches to reset mechanisms and at least one feedback simulator with a flow meter in the power circuit and a controllable throttle means incorporated between the control branches of the control circuit. The feedback simulator forms a combined feedback simulator consisting of the flow meter and the throttle means controllable in steps, the throttle means being formed as a combination of several connected controllable throttle means.
