STIRLING ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering, power engineering, transport. SUBSTANCE: hermetically sealed reservoir accommodating working medium 2 is made in form of one toroidal chamber 1. Device 4 for dividing chamber 1 into delivery space 5 and suction space 6 is arranged between inlet port 15 and outlet port 13 of toroidal chamber. Displacer 3 in form of rotary shutter 4 is free to pass in between. Fixing of shutter turn is provided. Novelty is toroidal shape of reservoir 1 and provision of device 4 organizing movement of working medium 2 by means of freely moving displacer 3 for instance, in form of ball, so that all four phases of working cycle take place simultaneously and isothermal expansion phase in chamber 1 is practically uninterrupted which provides useful work.
