METHOD OF AND DEVICE FOR ACCOMPLISHING WORKING CYCLES OF ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02B53/02 F02B53/08 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed method comes to displacement of compression blade in compression chamber and filling said chamber with fresh charge of fuel-air mixture. Fuel-air mixture filling compression chamber during previous cycle is pressure-fed into combustion chamber, is compressed in this chamber and is ignited. Expanding gases in working chamber separated by ridges from compression chamber press on working blade providing its working stroke and rotation of rotor. Waste gases of previous working cycle are forced out. In proposed method use is made of stop mechanisms to fix compression and working blades. Working blade is fixed when it passes by ridge separating in motion working chamber from compression chamber, with release of compression blade and keeping compression and working blades in this state when they pass compression chamber to following ridge in direction of motion at passing of which working blade is released and compression blade is fixed and this state of compression and working blades is preserved at passing working chamber to following ridge in direction of movement, and working cycle is thus completed. To execute proposed method, rotary internal combustion engine contains body, shaft, disk and ring construction units arranged in body for relative rotation. Disk construction unit has disk with slots accommodating compression and working blades installed for reciprocating, between which combustion chambers are arranged. Ring construction unit includes coaxial cylindrical tubular members of larger and smaller diameters, respectively, between which ring member with wavy surface forming ridges and valleys is placed. Wavy surface of ring member is pointed to end face surface of slotted disk and forms compression and working chambers together with outer surface of cylindrical tubular member of smaller diameter and inner surface of cylindrical tubular member of larger diameter, chambers being divided by ridges of ring member with wavy surface. Intake and outlet channels are made in ridges of ring member with wavy surface, alternating through one ridge. Each compression and working blade is spring-loaded by means of elastic element relative to disk with slots or body. Stop mechanisms are placed inside body to fix compression and working blades in required position relative to slotted disk.

EFFECT: increased compression ratio of fuel-air mixture, effectiveness of its use, efficiency of engine, reduced vibration loads.
