OSCILLATORY INTERNAL COMBUSTION ENGINE Russian patent published in 2014 - IPC F02B55/14 F01C9/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to propulsion engineering. Martine ICE comprises housing with circular working chamber, working shaft, PTO-shaft, at least two blades with seals, and starter. Webs with seals are rigidly secured to the housing inside working chamber. Blades are opposed to make cavities in said working chamber. Every said cavity comprises ignition chamber with fuel injection valve, exhaust gas discharge valve and spark plug. Engine incorporates mechanism to convert working shaft oscillation into pro-shaft rotation which includes to identical overrunning couplings and reversing coupling. Input links of overrunning couplings are engaged with working shaft extensions extending from the housing both sides. Output link of one overrunning coupling is engaged with one extension of PTO-shaft. Starter output link is engaged with working shaft end. PTO-shaft slides inside the hollow working shaft. Hub with blades is rigidly fitted on working shaft for blades to get in contact with web seals. Output link of the other overrunning coupling is engaged with input link of reversing coupling. Output link of reversing coupling is engaged with the other extension of PTO-shaft. Every ignition chamber is confined by the web curved part.

EFFECT: simplified design, decreased weight and overall dimensions.
