Abstract
A variable control valve for a gas compression system is disclosed for a gas compressor with a piston having a variable displacement within a compression chamber of the gas compressor. A pressure within a crankcase chamber of the gas compressor acts upon the piston A diaphragm within the control valve, controls a flow of high and low pressure gas into and out of the pressure chamber, thus controlling the displacement of the piston. The diaphragm is acted upon by a predetermined reference pressure within a reference chamber of the control valve. The predetermined reference pressure within the reference chamber is created by a flow into and out of the reference chamber of the high and low pressure gas. The predetermined reference pressure can be changed in order to optimize compressor output. This flow is controlled by reference chamber valve means ( ) operably coupled to the reference chamber, the reference chamber valve means being responsive to electrical signals.
