ABSTRACT:
An apparatus for loading a compressor includes a microprocessor based electronic controller, a pneumatically driven, spring loaded open first valve, and a normally open, electrically driven second valve flow connected in series with the first valve. The first valve and the second valve are fluidly disposed intermediate a receiver tank and the compressor. The second valve is disposed in signal receiving relation to the controller. An orifice and muffler combination is flow connected intermediate the first valve and the second valve. The orifice has a predetermined inside diameter dimension suitably sized to establish a pressure signal to close the first valve to thereby load the compressor. During operation, at a predetermined time, the controller closes the second valve thereby directing a predetermined volume of fluid to be compressed through the orifice and muffler combination to cause fluid pressure to rise to a predetermined magnitude, at which time sufficient actuation pressure is available for control of the spring loaded first valve.
