This paper presents operating characteristics on a Stirling refrigerator with an active type regenerator. When the Stirling refrigerator with the regenerator in a displacer uses light and flexible matrixes, those matrixes reciprocate in the regenerator housing. This phenomenon changes the flow loss and the residual gas volume in the regenerator matrixes. Moreover, the variation of the matrix volume influences the cooling capacity. Then, we propose the active type regenerator that actually transforms the matrix according to the reciprocation of the displacer. The active type regenerator uses an urethane matrix that the swelling and compression are done by the matrix piston.
