ABSTRACT:
In a double-acting rotary compressor having two compression spaces each constituted by at least one variable-volume compression chamber which is put into communication first with the suction enclosure and then with the discharge enclosure, the power consumption at low delivery is reduced by causing the two compression spaces to discharge in parallel into a common duct in the vicinity of maximum delivery and connecting the spaces in series for deliveries below a predetermined value by joining the outlet of the first space to the second space at a point at which the compression chamber is already isolated from the suction enclosure.
