Abstract
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.
