Title: Attachment of cylinders in the housing of free-piston stirling machines

Abstract

An improvement to a free-piston Stirling machine having a cylinder mounted within a housing. The cylinder has a flange for mounting the cylinder within the housing to a transition plate with a central opening for receiving the cylinder. An elastic rim bounds and surrounds the opening and extends in an axial direction from the plate to a crest of the rim. The crest of the rim is in contact against a first axially facing side of the cylinder flange. The interior side of the rim is outwardly spaced from the exterior side of the cylinder. A compliant clamp is attached to the transition plate and is positioned on the opposite, axially facing side of the cylinder flange. The compliant clamp has an elastic spring extending against the cylinder flange which applies a force urging the cylinder flange in an axial direction against the crest of the elastic rim.
