The Mechanical Freezer of this invention closely approaches an ideal freezer cycle composed of constant temperature compression, expansion, and constant volume heating (load transfer) by using power piston 106 that power input shaft 50 moves up and down and displacers 104 and 105 that are moved by cam 108. When power piston 106 moving up and additional displacer 105 moving down come together, fluid is forced through additional heat sink 41 where it is cooled as it is compressed. When additional displacer 105 and primary displacer 104 come together, fluid is forced through primary heat sink 40 where it is cooled as it is compressed. After compression, the cooled fluid is expanded by power piston 106 along with displacers 104 and 105 moving down. When displacers 104 and 105 then move up, fluid is forced through load 30 and load 30 is cooled.
