Digital capacity control is achieved by axially separating the scroll members. During the time the members are separated, there is no gas compression and approximately 10% power usage. By varying the amount of time the members are separated, capacity control between 10 and 100% can be achieved. The separation is achieved by bypassing a controlled amount of discharge gas to the suction side through a solenoid valve. The lowering of the pressure in the modulating chamber allows the scrolls to separate and as a result, no pumping action takes place
