COMPRESSOR

摘要

A variable capacity scroll compressor includes a fixed scroll. The fixed scroll of the compressor includes a bypass flow path configured to connect a suction unit to a compression unit, a cylinder space provided on the bypass flow path, and an on/off valve disposed to be movable back and forth in the cylinder space to open/close the bypass flow path according to a difference between a discharge pressure of the discharge unit and a suction pressure of the suction unit. Thus a capacity of the compressor may be reduced by connecting the suction unit to the compression unit under a low load condition in which a difference between a discharge pressure and a suction pressure is relatively less.

1. A compressor, comprising:
a case; a fixed scroll fixed to an inside of the case; an orbiting scroll provided to move about the fixed scroll; a compression unit formed by the fixed scroll and the orbiting scroll and configured to have a volume that is reduced while the compression unit moves toward the center of the fixed scroll and the orbiting scroll, according to the movement of the orbiting scroll; a suction unit configured to suction refrigerant to be delivered to the compression unit; and a discharge unit to which refrigerant compressed by the compression unit is discharged, wherein the fixed scroll comprises a bypass flow path configured to connect the suction unit to the compression unit, a cylinder space provided on the bypass flow path, and a valve disposed to be movable back and forth in the cylinder space to open and close the bypass flow path according to a difference between a discharge pressure of the discharge unit and a suction pressure of the suction unit.
