Abstract

An externally heated, regenerative heating and refrigerating machine working according to the Vuilleumier cyclic process has a pressure-tight housing (1) with two linearly and coaxially movable pistons (2, 3) arranged therein that delimit together a warm working volume (5). One of the pistons (2) delimits in the housing (1) a hot working volume (7) externally supplied with heat (6) by means of a burner (22) and the other piston (3) delimits a cold working volume (7). All three variable working volumes (5, 6, 7) communicate with each other through intermediate regenerators and heat exchangers. A control gear (S) for the pistons (2, 3) is arranged in the housing (1). The housing (1) is designed as a tubular pressure vessel (1') with forward and return flow connecting branches (10 to 13) for two heat transfer circuits. All regenerators (8, 9) and heat exchangers (14, 15) are arranged within the pressure vessel (1'). A piston bushing (16) with overflow openings (17, 18, 19) that lead to the working volumes (5, 6, 7) is also arranged in the pressure vessel (1'). The heat exchanger (15) for one of the heat transfer media delimits the cold working volume (7) on the one side and on the other side it delimits a space (70) in which is arranged the control gear (S) that cooperates with the piston (2, 3).
