Free piston free displacer cryocoolers in the small capacity miniature range, used for cooling infrared sensors, have a long operating life without maintenance. This paper shows the complete dynamics and thermodynamics of the free piston free displacer miniature cryocooler including the pressure loss due to the flow through the regenerator and the variation of the pressure in the bounce space.
