Claim 14:
15. A beta-type Stirling machine operating in refrigerating mode, said Stirling machine comprising:
a cold part and a hot part;
a displacer piston comprising a friction zone;
a power piston comprising a friction zone; and, a single liner positioned in the hot part of the Stirling machine operating in refrigerating mode, in which single liner the friction zones of the displacer piston and of the power piston slide, the single liner extends from a lower end-of-stroke of the friction zone of the power piston, called crankcase end of the single liner, said lower end-of-stroke of the friction zone of the power piston being situated on the side of a crankshaft of the power piston, up to an upper end-of-stroke of the friction zone of the displacer piston, called separation end of the single liner, said upper end-of-stroke of the friction zone of the displacer piston being situated on the side of a heat exchanger.
