Summary:PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of improving reliability by suppressing abrasion of a valving element of a check valve disposed at the outlet side of a cyclone-type oil separator.SOLUTION: A refrigeration cycle device includes: a compressor 1; a cyclone-type oil separator disposed at the outlet side of the compressor and separating an oil from a compressed refrigerant gas; and a check valve 3 disposed at the outlet side of the cyclone type oil separator. A rectifier 2 for decreasing a swirling flow velocity of swirl flow discharged from the cyclone type oil separator, is disposed between the cyclone type oil separator and the check valve. 【課題】サイクロン式オイルセパレータの出口側に設けられた逆止弁の弁体の摩耗を抑制することにより信頼性を向上できる冷凍サイクル装置を得る。【解決手段】冷凍サイクル装置は、圧縮機1と、この圧縮機の出口側に設けられ、圧縮された冷媒ガスから油を分離するためのサイクロン式オイルセパレータと、このサイクロン式オイルセパレータの出口側に設けられた逆止弁3とを備える。また、前記サイクロン式オイルセパレータと前記逆止弁との間には、前記サイクロン式オイルセパレータから吐出される旋回流の旋回流速を減速するための整流装置2を備えている。【選択図】図1
