ABSTRACT:
A multi-stage fluid compressor has an input and an output line and variable volume cylinders. A plurality of actuators change the volumes of the cylinders in accordance with control signal. Sensors sense the pressure of fluid entering each stage and provide signals representative of the sensed pressures. Another sensor senses the pressure of the discharge fluid and provides a corresponding signal. A circuit connected to the actuators and to the sensors provides the control signals to the actuators in accordance with the pressure signals from the pressure sensors.
