Control device for hydrostatic system

摘要

The control device has a pair of rev sensors, respectively providing electrical signals representing the input revs of a variable displacement pump and the output revs of a variable displacement motor. The displacement of the pump and the motor are controlled via a pair of electromagnetically-operated proportional valves, receiving control signals from a microprocessor in dependence on the the received rev signals, a required input signal and the defined operating parameters of the hydrostatic system.
