FIELD: mechanical engineering; engines, cryogenic gas machines and heat pumps employing for their operation Stirling cycle principle. SUBSTANCE: main part of drive is rotor rigidly fitted on output shaft. Engine cylinders with pistons and connecting rods are arranged on stationary housing around output shaft in parallel with shaft. Connecting rods are provided with sliders fitted in guides. Sliders are connected with rollers placed in rotor endless groove made on rotor side surface. Geometric form of groove makes it possible for some opposite pistons to reciprocate in opposite directions, with other opposite pistons remaining motionless and, vice versa, simultaneously turning the rotor together with output shaft through half a revolution at each working stroke of pistons. Combined movement of all pistons near their dead centers is also provided which makes it possible to displace compressed working medium from cold to hot working space. It follows from above statement that each piston can execute two working stroke with stop in between at one revolution of rotor (downwards, stop, upwards, stop); geometric form of groove coincides with form of curve representing relationship between displacement of rotor side surface at rotation and displacement of any pistons (rollers). EFFECT: materially increased efficiency of engine owing to provision of interrupted movement of pistons. |
