Abstract
Lift valves are used for controlling the capacity of a rotary compressor and to vary the built-in volume in the rotary compressor. When controlling the capacity of the rotary compressor, the built-in volume is adjusted by controlling the opening and closing of the lift valves in relation to one another.
