The casing ( 1 ) of a positive displacement machine has a cylindrical internal surface ( 3 ) delimiting an operating chamber which accommodates an orbiting piston ( 4 ) having a cylindrical external surface. At least one of the said surfaces, e.g. the internal surface ( 3 ), is at least partly constituted by a peripheral wall ( 2 ) having a front surface facing the operating chamber and a rear surface. The peripheral wall ( 2 ) having through-slots ( 22 ) which extend parallel to one another and accommodate respective compliant strips ( 24 ) extending from the front surface to the rear surface. The strips ( 22 ) are retained in the slots ( 22 ), against pressure in the operating chamber, by a retaining device such as a clamping member ( 28 ). An assembly of three positive displacement machines and engines comprising first and second positive displacement machines are also described.
