Compressor

摘要

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.

主权项

1. A compressor comprising:
a housing; a compression unit arranged in the housing, wherein the compression unit draws in, compresses, and discharges refrigerant gas; a discharge chamber in communication with the compression unit; an outlet in communication with the discharge chamber, wherein the outlet is formed in the housing to discharge the refrigerant gas out of the housing; and an oil separation structure arranged between the discharge chamber and the outlet, wherein the oil separation structure separates lubrication oil from the refrigerant gas and accumulates separated lubrication oil, and the oil separation structure includes: an oil reservoir that accumulates the lubrication oil separated from the refrigerant gas, an oil separation compartment that is located upward from the oil reservoir and is in communication with the oil reservoir, an intake passage that extends upward from the oil separation compartment and is in communication with the discharge chamber, wherein the intake passage draws the refrigerant gas from the discharge chamber into the oil separation compartment to separate the lubrication oil from the refrigerant gas, an exhaust passage that extends upward from the oil separation compartment and is in communication with the outlet, wherein the exhaust passage discharges the refrigerant gas from the oil separation compartment through the outlet and out of the housing, and a supply passage that extends upward from the oil separation compartment and has a larger cross-sectional area than the intake passage, wherein the supply passage supplies the separated lubrication oil from the oil separation compartment to the oil reservoir.
