Abstract
A rotary compressor comprises a rotary shaft for compression action, a bearing which supports the rotary shaft and includes a discharge valve to discharge compressed gas and a sound suppression cover which covers the discharge valve, so that an annular discharge chamber is formed between the sound suppression cover and the bearing. At least one tubular cavity section with a bottom is provided to open into the discharge chamber at a location adjacent the discharge valve. The tubular cavity section has a length approximately one-fourth of the average circumference length of the discharge chamber.
