FIELD: engines and pumps.
SUBSTANCE: mechanism of gas distribution of phases of internal combustion rotor engine contains working shaft 1 interacting with roller 3 by means of eccentric 2 fixed on it. Roller 3 is mounted in control device of working gap between rotor 4 and flaps 5 in combustion chambers. Working shaft 1 is connected to gear transmission 7 with a spool-type device including spool 8 with a seal. Sealing is provided by sealing plates and sealing rings. Sealing plates press to working surface of spool-type jacket 13 with flat springs providing sealing all over the perimetre of inlet 11 and exhaust 12 channels of the spool. Gear transmission 7 is connected by serration to a sleeve connected to a key with spool 8. During adjustment of gas distribution of phases hold-down nuts provide a gap between the sleeve and gear transmission 7. Adjustment is performed upon changing type of fuel.
EFFECT: simplifying the design, improving reliability and efficiency of gas distribution mechanism.
