Abstract
A rotary compressor has an outlet port with a variable area for discharging compressed medium from a working chamber to the outlet. The degree of opening of the outlet port is controlled by a regulator which senses the energy supplied to the compressor for compressing the medium and which from time to time changes the degree of opening of the outlet port until the need of drive energy for the compressor becomes minimal.
