Title: Refrigerant suction structures for compressors

Abstract: Suction ports corresponding to individual cylinder bores are formed in a partition plate. A refrigerant feeder channel is provided on a rear wall of a rear housing whose internal space is partitioned chiefly into a suction chamber and a discharge chamber. A structural wall of the refrigerant feeder channel constitutes an integral part of the rear housing. The refrigerant feeder channel is formed from an outer cylindrical wall of the rear housing, extends across the discharge chamber and opens into the suction chamber. An outflow opening of the refrigerant feeder channel has a slanting edge so that it opens toward the partition plate. The outflow opening is so positioned that its center lies on an axis of a rotary shaft.
