Multistage oil separator

A refrigerator () has a housing (), a cylindrical working chamber (), a cylindrical displacing member (), a gap () which is located between the housing and the displacing member, a regenerator which is disposed inside the displacing member, and a device alternatingly supplying the working chamber with an effective high-pressure gas and an effective low-pressure gas. In order to overcome the disadvantages associated with gas streams occurring in the gap (), an additional regenerator (gap gas regenerator), () is assigned to the gap ().
