Abstract	The performance characteristics of Stirling machines with free moving pistons were studied. The design of the small free piston Stirling refrigerator, is described and a new way to describe the pressure fluctuations in the Stirling system is given. The equations of movement of the piston and the displacer are derived. A small cryogenic cooler, based on the free displacer Stirling principle, was designed and developed with a capacity of 1 W at 77 K. The main application is for infrared radiation detection. The concept leads to a machine with a very long life requiring no maintenance and having negligible degradation. The machine, has shown a long lifetime and a very stable lowest temperature. The pressure fluctuation in the machine which leads to an explanation of the behavior of a free displacer refrigerator is descrbed and the linear drive system of the machine is discussed.
