20130183183 | ROTARY ENGINE - A “cat and mouse” rotary engine/pump comprising two inclined power shafts at the two ends of the rotor-pistons. Each power shaft connects to both rotor-pistons by concentric crosses. Either piston can be suspended from the bearings of the inclined shafts indirectly, through the inclined shafts and the crosses, avoiding any touching with the other piston and the casing. The arrangement improves the balance of the engine, rids the bearings of the rotor-pistons from heavy idle loads, allows lighter and more robust structure. The power is shared between the two counter-rotating shafts. The arrangement fits to divided load applications, like portable flyers, REM. | 07-18-2013 |

20100229834 | VARIABLE COMPRESSION RATIO ENGINE - To control the compression ratio of an internal combustion engine, the cylinder block is slidably fitted to the crankcase, projections from the crankcase extend into the cylinder head to support a control shaft bearing the cylinder head. The angular displacement of the control shaft varies the compression ratio by displacing the cylinder head relative to the crankcase. | 09-16-2010 |

20090050733 | SIMPLE VTOL FLYING MACHINE - A compact and lightweight portable flyer. | 02-26-2009 |
20090165744 | PULLING ROD ENGINE - The piston is connected to the crankshaft via a connecting rod, while the crankshaft is disposed between the wrist pin and the combustion chamber. This way the combustion is shifted to the slow dead center, enabling the diesel to perform at higher revs, improving the spark engine efficiency and making HCCI combustion easier. Though the crankshaft is of one piece, more connecting rods can be used for a piston. As opposed piston, the PRE engine further combines top specific power, top thermal efficiency, built in scavenging pumps, and compactness. | 07-02-2009 |
20120037129 | OPPOSED PISTON ENGINE - A single-crankshaft single-cylinder fully-balanced opposed piston engine module that provides extra time for the injection and the combustion of the fuel. | 02-16-2012 |
20130133627 | RECIPROCATING PISTON ENGINE - A single-crankshaft single-cylinder fully-balanced opposed piston engine module that provides extra time for the injection and the combustion of the fuel. | 05-30-2013 |
20140234146 | CONNECTING ROD VALVE - A valve integral with, or secured to, the connecting rod small end of a reciprocating piston positive displacement machine opens and closes a port controlling the communication of two spaces, for gas pumps, scavenging pumps, compressors, superchargers, pumps etc. | 08-21-2014 |
