FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: used in drive are two planetary trains with equal gear ratio which provides angular shifting of camshaft relative to drive sheave of timing mechanism. Each train contains central shaft. Central shaft of one of trains is coupled with timing gear sheave, and other shaft is coupled with camshaft, its central wheel being coupled with rotary actuating mechanism.
EFFECT: simple and compact design of device.
