Abstract
A compression mechanism portion housed in a closed case is provided with a partition plate located between a first cylinder and a second cylinder. The compression mechanism includes a first bearing discharge port formed to a first bearing and a first partition plate discharge port formed to the partition plate as discharge ports for discharging working fluid compressed in a first cylinder chamber, and also includes, as discharge port for discharging working fluid compressed in a second cylinder chamber, a second bearing discharge port formed to a second bearing and a second partition plate discharge port formed to the partition plate. A cross-sectional area of the first partition plate discharge port is formed to be smaller than a cross-sectional area of the first bearing discharge port, and a cross-sectional area of the second partition plate discharge port is formed to be smaller than a cross-sectional area of the second bearing discharge port.
