MULTICYLINDER FREE-PISTON ENGINE-COMPRESSOR UNIT Russian patent published in 2017 - IPC F02B71/04 

FIELD: engines and pumps.

SUBSTANCE: free-piston engine-compressor unit consists of 2-12 cylinder blocks mounted on a common base plate (1). Blocks contain one cylinder of two-stroke internal combustion engine (2) and piston compressor (3). Center lines of cylinder blocks are parallel to each other and perpendicular to the plane of the common base plate. Pistons of all the blocks are interconnected by timing mechanism (4). The timing mechanism comprises crossheads (22) positioned in the guides of the common base plate (25) coaxially to the cylinders of the engine and the compressor, with rigidly attached engine rods of the engine (23) and the compressor (24) to them, racks (26) are cut on the side surface of the crossheads from the direction of adjacent cylinder blocks, which engage with ring gears of rockers (27) positioned between the crossheads. Rocker number is one less than the cylinder block number.

EFFECT: improved device operation reliability.
