AXIAL-PISTON ENGINE Russian patent published in 2008 - IPC F02B75/28 

FIELD: engines and pumps.

SUBSTANCE: axial-piston engines incorporates a compressor chamber cylinder block with intake and return valves, the compressor chamber cylinder block with pistons and rods, the working chamber cylinder block with pairs of opposed cylinders with two opposed pistons in each. The drive shaft with the camshaft drive gear wheel runs coaxially with the cylinders. Two plates, inclined towards each other, are fitted onto the drive shaft with the outer surfaces supporting in plain bearing the swinging washers, one for every pair of the cylinders, furnished with journals and levers inhibiting rotation and swinging in bearings. The guide cylinders house traveling thrust pistons with hinges rigidly tied, via the rods, to the pistons. Every working cylinder accommodates three groups of combustion chambers, nozzles, intake, return and exhaust valves arranged at the cylinder center and along its edges to facilitate gas exchange and increase the output by allowing idling in both direction of the piston travel.

EFFECT: higher efficiency.
