MULTI-CYLINDER THERMAL MACHINE WITH CONTROLLED OUTPUT AND WITH EXTERNAL HEAT SUPPLY Russian patent published in 2012 - IPC F02G1/44 F02G1/45 F16D3/10 

FIELD: machine building.

SUBSTANCE: multi-cylinder thermal machine with controlled output and with external heat supply includes groups of cylinder-piston pairs on hot and cold sides of machine, power adjustment coupling and crankshafts. Pistons of group of cylinder-piston pairs on hot side of machine are connected by means of stocks and piston-rods to the first crankshaft. Working cavities of group of cylinder-piston pairs on hot side of machine are connected via pipelines to in-series located heaters, regenerators and coolers and to working cavities of group of cylinder-piston pairs on cold side of machine. Pistons of group of cylinder-piston pairs on cold side of machine are connected by means of additional stocks and additional piston-rods to the second crankshaft. The second crankshaft is connected by means of the first chain transmission to the left half-axis of power adjustment coupling. The first crankshaft is connected by means of the second chain transmission to the right semi-axis of power adjustment coupling. Control pulley of the coupling is connected through rotation transmission element to control electric drive. Non-working cavities on rear side of pistons on hot side of the machine are connected in pairs to each other via pipelines. Non-working cavities on rear side of pistons on cold side of the machine are also connected in pairs to each other via pipelines. Total volume of non-working cavities connected via pipelines does not change.

EFFECT: increasing the power, service life and enlarging functional capabilities of thermal machine.
