PCT WORLD INTELLECTUAL PROPERTY ORGANIZATION International Bureau INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (57) Abstract The present invention relates to a Stirling free piston cryocooler (I) in which the drive assembly is arranged in an in-line opposed piston arrangement. The displacer piston assembly (11) is nested within the power piston assembly (10). In one embodi- ment the thermodynamic assembly is connected to the drive mechanism in a tee arrangement so that the opposed cryocooler pis- tons share a common expansion space (24). In another embodiment the thermodynamic assembly is connected to the drive me- chanism in a double split tee arrangement with the thermodynamic components remotely located from the expansion (103) and compression spaces (104) and connected thereto by flexible tubes (105, 106).
