Document Type and Number:
Japanese Patent JP2003269348
Kind Code:
A
Abstract:
To reduce the over-compression loss at the time of discharge of a refrigerant in a swing compressor.
The outer surface shape of a swing piston 28 is non-circular, and the inner surface shape of a cylinder chamber 25 is formed based on the envelope of the outer surface of the swing piston 28 when the swing piston is swinging. The outer surface shape of the swing piston 28 and the inner surface shape of the cylinder chamber 25 are formed in the shape of an egg, etc., so that the compression stroke is shorter and the discharge stroke is longer in the operation of the swing piston 28 than when the shapes are circular.
