A refrigerator ( 1 ) has a housing ( 2, 14, 19 ), a cylindrical working chamber ( 15, 21 ), a cylindrical displacing member ( 11, 17 ), a gap ( 36, 38 ) 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 ( 36, 38 ), an additional regenerator (gap gas regenerator), ( 43 ) is assigned to the gap ( 36, 38 ).
