Kuznetsov Current piston expansion engines are usually produced as single-row engines on individual bases with a reduced fre- quency of revolution of the shaft n < 500 rpm and a mean speed of the piston of Cp < 1.5 m/sec, and are fitted with a forced gas distribution system. This results in unsatisfactory parameters of specific metal reqimement, low reliability in operation, and increased expenditure in the manufacture of the expansion engine. Regardless of the tact that two-stage expansion of the gas in high-pressure cycles is more efficient [1-3], piston expan- sion engines are still produced in the single-stage form. This is associated with the lack of any completely new design solutions which would make it possible to carry out two-stage expansion without any large increase in the complexity of the design of the expansion engine and without impairing its technical-economic parameters, such as specific metal requirement, reliability, over- all dimensions, etc. Transition to two-stages expansion is efficient in the case of a sufficiently large gain in the efficiency if these conditions are fulfilled. Attention will be given to the
