Abstract
There is provided a horizontal rotary compressor capable of improving performance thereof while an oil supply means smoothly supplies oil. A part of a hermetic shell case at the upper side is partitioned by a baffle into an electric element side and an oil pump side, a refrigerant which is drawn from an outside of the hermetic shell case is compressed by a first rotary compression element and a second rotary compression element and discharged toward the electric element side of the baffle, then it is further discharged from oil pump side toward the outside of the hermetic shell case. The baffle closes a flow path area of the refrigerant over an oil level inside the hermetic shell case at a ratio ranging from not less than 50% to not more than 80% during the stoppage of the horizontal rotary compressor.
