ABSTRACT:
An apparatus includes a compressor having a rotor portion, an inlet and a discharge. A motor portion of the apparatus has an intake manifold connected to the discharge. A throttle is displaceable between an open and a closed position for controlling fluid flow between the discharge and the intake manifold. A bypass return line connects the rotor portion of the compressor to the inlet. A piston valve, movable between an open location and a closed location, controls flow through the bypass return line. A control line, connecting the intake manifold to the piston valve, controls the location of the piston valve. A control valve may be included to control fluid flow through the control line. A computer, which is affected by the operation of the motor, controls the position of the control valve.
