ABSTRACT:
An apparatus includes a rotary compressor having an inlet end, a discharge end, and a predetermined built-in volume ratio. The compressor has at least one rotor which is encased by a housing which is defined by at least a first portion and a second portion. The second housing portion has formed therein a first discharge port dimensioned as a function of the predetermined built-in volume ratio. A removable plate has formed therein a second discharge port dimensioned as a function of the predetermined built-in volume ratio. The removable plate mounts on the housing intermediate the first and second housing portions. When the plate is mounted on the housing the first and second ports cooperatively, fluidly communicate with the discharge end of the compressor.
