Abstract
An electric compressor capable of preventing the occurrence of pulsation noise by increasing a volume of a discharge chamber. The electric compressor includes a housing, a compression unit, a driving unit in the housing which drives the compression unit, a rear housing having a discharge chamber through which refrigerant compressed in the compression unit is discharged, an oil separator disposed in the discharge chamber, and a bleed unit configured to communicate with a lower side of the oil separator so that some oil contained in the refrigerant discharged to the discharge chamber moves toward the oil separator.
Claims12
An electric compressor comprising:
- a housing;
- a compression unit configured to compress a refrigerant;
- a driving unit which is provided in the housing and drives the compression unit;
- a rear housing having a discharge chamber through which the refrigerant compressed in the compression unit is discharged through a discharge hole;
- an oil separator disposed in the discharge chamber;
- and
- a bleed unit configured to communicate with a lower side of the oil separator so that some oil contained in the refrigerant discharged to the discharge chamber moves toward the oil separator, wherein the bleed unit includes:
- an inlet which has a predetermined size and communicates with the discharge chamber;
- a passage extending from the inlet toward the oil separator;
- and
- an outlet which is open from the passage toward an inside of the oil separator, wherein the inlet is formed to have a larger inner diameter than the outlet.
