Patent ID: 6893237

Claim:
A horizontal rotary compressor comprising: a horizontal hermetic shell case; an electric element housed in the hermetic shell case; a rotary compression mechanism which is driven by the electric element; said rotary compression mechanism comprised of a first rotary compression element and a second rotary compression element; lubricant stored in an oil reservoir at the bottom inside the hermetic shell case; an oil supply means provided at an opposite side of the electric element of the rotary compression mechanism for supplying oil to the rotary compression mechanism; wherein a part of the hermetic shell case at the upper side is partitioned by a baffle plate ( 200 ) into the electric element side and oil supply means side, a refrigerant which is drawn from an outside of the hermetic shell case is compressed by the rotary compression mechanism and discharged toward the electric element side of the baffle plate ( 200 ), then it is further discharged from oil supply means side toward the outside of the hermetic shell case, whereby the portion positioned under oil level is partitioned by oil while the portion positioned over oil level is closed to the extent not to inhibit the circulation of the refrigerant so that a pressure in the hermetic shell case is set such that a pressure at oil supply means is lower than a pressure at the electric element of the baffle plate ( 200 ), wherein said baffle plate ( 200 ) is positioned between said oil supply means and said rotary compression mechanism.
