SPOOL-TYPE TIMING GEAR

摘要

mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to carburetor engines and engines with direct injection of fuel into intake manifold. Proposed device has housing 3 with main channel 6 connected with engine cylinder 7, with intake channel 5 and outlet channel 4 and with rotary spool 1 arranged in housing 3. Recess-gas conduit 2 is made on side surface of spool. Recess-slot 8 is made in housing 3 after intake channel 5 in direction of rotation of spool 1. Spring 9 and blade- scraper 10 pressed to side surface of spool 1 are arranged in recess-slot 8. EFFECT: elimination of fuel losses in engines with spool-type timing gear. 1 dwg
