Abstract
A compressor includes a housing, compression unit, discharge chamber, outlet, and oil separation structure. The oil separation structure, which is arranged between the discharge chamber and the outlet, includes an oil reservoir, oil separation compartment, intake passage, exhaust passage, and supply passage. The oil separation compartment is located upward from the oil reservoir. The intake passage, which extends upward from the oil separation compartment, draws refrigerant gas into the oil separation compartment from the discharge chamber to separate lubrication oil from the refrigerant gas. The exhaust passage extends upward from the oil separation compartment and discharges the refrigerant gas in the oil separation compartment out of the housing through the outlet. The supply passage extends upward from the oil separation compartment and has a larger cross-sectional area than the intake passage. The supply passage supplies the oil reservoir with lubrication oil from the oil separation compartment.
