Abstract
A discharge pulsation reducing cooler B is provided to cover the circumferential periphery of a compressor A. The discharge pulsation reducing cooler B has a delivery passage and a jacket covering that, and cooling water is circulated through a passage formed between the delivery passage and the jacket . Delivered air flowing through the delivery passage is cooled by the cooling water. In particular, because heat exchange efficiency is promoted by turbulence caused by the pulsation in the delivery passage , the delivered air is cooled efficiently. Also, pulsation is reduced in first and second expansion chambers in the delivery passage , and pulsation noise in the delivery passage is reduced by the cooling water passage and the jacket
