Abstract
An oil separator for separating oil from exhausted gas containing refrigerant gas and fine particles of oil incorporated in the refrigerant gas including grooved plates each formed with a multiplicity of grooves on opposite surfaces to allow the exhausted gas to flow in a direction substantially at right angles to the grooves, whereby the fine particles of oil can be trapped by the grooved plates. The oil separator can achieve increased oil separation efficiency.
