Hermetically sealed rotary compressor and refrigeration cycle device

A hermetically sealed rotary compressor, which comprises a compressor body, configured so that an electric motor unit is accommodated in an upper part of a well-closed container and a compression mechanism section, which is driven by the electric motor unit through a shaft, is accommodated in a lower end portion of the well-closed container, a support leg disposed on a lower end portion of the well-closed container and comprising a mounting hole attached and secured to a mounting spot, and an accumulator disposed on a lateral part of the well-closed container,

• an overall height H of the compressor body, which is a height measured from the bottom surface of the support leg to the upper end of the compressor body, being set to be 2.5 or more times as great as an outer diameter D of the compressor body (H/D≧2.5),
• a height Hg of the center of gravity of the compressor body, which is a height measured from the bottom surface of the support leg to the center of gravity of the compressor body, being set to be ½ or less the overall height H of the compressor body (Hg≦H/2),
• the hermetically sealed rotary compressor comprising four or more said mounting holes, based on the fulfillment of the following expression (1):
• Rc/cosθ<Rb, Rb<L, (1)
• where Rb is the support point radius of the support legs (distance from a longitudinal central axis of the compressor body to the center of the mounting hole of each of the support legs), Rc is the outer radius of the compressor body (distance from the longitudinal central axis of the compressor body to the outer peripheral surface of the compressor body), L is the distance from the longitudinal central axis of the compressor body to a longitudinal central axis of the accumulator, and θ is an angle (45° in the case of four equally spaced legs) half an angle formed between adjacent support legs about the longitudinal central axis.
