NON-CRANK TWO-STROKE INTERNAL COMBUSTION ENGINE Russian patent published in 2012 - IPC F02B75/26 F02B75/32 F01B3/08 F01B9/06 

FIELD: engines and pumps.

SUBSTANCE: non-crank two-stroke internal combustion engine includes cylinder (2), sleeve (3), piston (8) connected to cylinder by means of rotary bodies connected to curved endless slot (14), and outlet shaft (12). Piston (8) consists of two component parts: pusher (9) with bearing (10) and piston head (11) installed on it. Endless curved slot (14) is made on side surface of pusher (9). The latter performs rotational movement transferred to outlet shaft (12). Piston head (11) is capable of back-and-forth movement along outlet shaft (12). Rotary bodies connected to curved endless slot (14) consist of roller bearings (15) installed on bearings (16) mounted in cylinder (2). Torque moment to outlet shaft (12) is transferred through ball bearings (13).

EFFECT: improving reliability and increasing service life due to lower friction coefficient and prevention of jamming of connected parts.
