ROTARY COMPRESSOR
Document Type and Number:
Japanese Patent JP2018080659
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the compression efficiency deterioration of a rotary compressor by reducing the flow path resistance of refrigerant flowing in a refrigerant passage hole.SOLUTION: In the rotary compressor, S1>S3, S2>S3, and S2'>S3' are established, where S1 is the cross section area of the refrigerant passage hole in a lower end plate, S2 is the cross section area of the refrigerant passage hole in a lower cylinder, S3 is the cross section area of the refrigerant passage hole in an intermediate partition plate, S2' is the overlapping area of the cross section of the refrigerant passage hole in the lower end plate and the cross section of the refrigerant passage hole in the lower cylinder, and S3' is the overlapping area of the cross section of the refrigerant passage hole in the lower cylinder and the cross section of the refrigerant passage hole in the intermediate partition plate.SELECTED DRAWING: Figure 9
