Abstract

The height measured from the bottom surfaces of support legs is set to be 2.5 or more times as great as the outer diameter of the compressor body, the height of the center of gravity measured from the bottom surfaces of the support legs to the center of gravity is set to be ½ or less the overall height, and the support legs are provided in number of four, based on the fulfillment of Rc/cos θ<Rb<L. Here Rb is the support point radius of the compressor body, Rc is the outer radius of the compressor body, L is the distance from a longitudinal central axis of the compressor body to a longitudinal central axis of an accumulator, and θ is an angle half the angle formed between the adjacent support legs about the central axis.
