POWER PLANT Russian patent published in 2016 - IPC F02B71/04 

FIELD: engines and pumps.

SUBSTANCE: power plant including a closed hydraulic circuit containing two propulsion-and-pump devices interacting with a hydraulic engine; each propulsion-and-pump device is provided with opposite free differential pistons, liquid-cooled internal combustion engines with gas cylinders, operating cylinders and hydraulic cavities of cylinders of differential pistons, a turbocompressor and a turbine on exhaust gases, a hydraulic engine connected to payload and connected via hydraulic lines to hydraulic cavities of cylinders of differential pistons of propulsion-and-pump devices, control devices of liquid flows in one direction, fuel supply, a starter; with that, the propulsion-and-pump device is provided with a crankcase with a reversible damper, which forms a hydraulic cavity with cylinders of differential pistons, and two opposite holes; hydraulic lines of a closed circuit are adjacent to the crankcase on both sides and interact with inlet and outlet holes of the hydraulic engine.

EFFECT: reduction of mass-and-dimensional characteristics and improvement of efficiency.
