A hydrostatic servomechanism adapted for controlling the direction of vehicles and selfpropelled machines. The servomechanism has a power circuit including a servopump, a distributor with reset mechanism, and a servomotor and a control circuit with a measuring pump connected through the control branches to the reset mechanism of the distributor and actuated by means of a command element, for example a vehicle steering wheel. The invention provides a simple reliable servomechanism with an artificial feedback simulator, non-sensitive to various harmful effects, providing a relatively stable and easily selectable gear ratio between the input and output parts of the servomechanism. The feedback simulator comprises a flow meter, a power circuit, and a controllable throttle means mechanically connected to the flow meter, the feedback simulator being incorporated between the control branches of the control circuit.
In a hydrostatic servomechanism adapted for controlling the direction of vehicles and selfpropelled machines, said servomechanism including a power circuit comprising at least one servopump, at least one servomotor, a distributor and connecting piping and a control circuit comprising a measuring pump actuated by a command element, the control circuit having control branches, and reset mechanism for the distributor, the servomechanism being connected by the control branches to the reset mechanism of the distributor, the improvement which comprises at least one feedback simulator, the feedback simulator comprising a flow meter, a power circuit, and a controllable throttle means mechanically connected to the flow meter, the feedback simulator being incorporated between the control branches of the control circuit.
