A rotary compressor includes a top clearance volume formed between a cylinder chamber and at least one delivery valve. Another top clearance volume, in communication with the cylinder chamber, produces a reverse flow of compressed fluid which generates pulsations adapted to offset a high frequency component of pulsations generated in the cylinder chamber by compressed fluid reversely flowing from the first top clearance volume to the cylinder chamber. Thereby the high frequency component of pulsations generated in the cylinder chamber is eliminated, and a low-noise rotary compressor is provided.

Rotary compressor with clearance volumes to offset pulsations

A sealed type motor-compressor having such structure that a refrigerant gas is directly led from an intake pipe to a cylinder, is described herein. The sealed type motor-compressor is characterized in that between an intake pipe opening within a sealed housing and a gas inlet portion of a cylinder, is provided a connecting member which can slidably follow a relative movement in every direction of an internal component of said motor-compressor.
