Claim 0:
1. 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 comprises passage ducts of a gas moving from a compression space volume of the Stirling machine operating in refrigerating mode, to a cooler of the Stirling machine operating in refrigerating mode, or vice versa, said passage ducts passing through the single liner.
