TOROIDAL CYLINDER STEAM ENGINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: rotary wall with a drive is mounted for periodical cylinder movement and is made in the form of a cylindrical flap with a profile hollow, the flap has two-stage journals. The journals are mounted in side walls of a toroidal cylinder for rotation by a crank mounted on one of the journals. The journals are turned into a position providing free passing of a piston by a cam fastened to a power take-off shaft of the engine, and a position providing parting of the cylinder into an expansion chamber and a discharge cavity - under the action of a spring. The piston bottom is made in the form of a wedge and has heat accumulators opposite to which water sprayers are mounted in the cylinder. The cylinder inlet port is connected to a steam generator through a disk spool. A seal device is mounted between the spool and the steam generator. The device has a spring-loaded drum, a bell fastened to the steam generator pipe. The discharge port of the cylinder communicates with a steam condenser located opposite to a fan. EFFECT: improved structure. 6 dwg
