Abstract

A compressor, used for compressing a working fluid to be discharged into a reservoir, includes at least one compressor element. A prime driver, capable of operating at varying angular velocities, applies motive force to the compressor. A ratio maintaining device, disposed between each compressor element and the prime driver, ensures that a ratio defined as an angular velocity of the compressor element divided by the angular velocity of the prime driver remains constant. The prime driver is typically internal combustion engine powered. A controllable fuel valve is in communication with the prime driver and is positionable for controlling a fuel flow to the prime driver. A controller positions the fuel valve based upon a combination of parameters including a variable setpoint reservoir pressure, ambient pressure and ambient temperature, wherein the prime driver is operated at an angular velocity at which the actual pressure at the reservoir can be maintained at the setpoint reservoir pressure. The controller is microprocessor or microcomputer based.
