ICE GAS DISTRIBUTION MECHANISM DRIVE Russian patent published in 2018 - IPC F01L1/34 F02D13/02 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines (ICE). ICE gas-distributing mechanism drive consists of the exhaust valves camshaft (5), the inlet valves camshaft (9) and sprockets (6) and (8) with chain transmission (7). To the exhaust valves camshaft (5) conical wheel (10) is attached, which is interconnected with the rigidly fixed to the centrifugal regulator (12) shaft response wheel (11). Centrifugal regulator (12) clutch (13) is provided with the frame (14), pivotally connected to the movably mounted in the cylinder block (17) head three-profile cam (16). Three-profile cam (16) interacts with the square cross-section spring-loaded rod (19). Rod (19) is movably located in the similar cross-section bushing (20), rigidly fixed in the cylinder block (17) head. Rod (19) is connected to the disk (21) made of diamagnetic material. On its end surface the disk (21) is provided with rectangular projections (22) made of permanent magnets, adjacent with the gap to the magnetically conductive protrusions (25), rigidly attached to the intake valves camshaft (9) sprocket (8) end face. Sprocket (8) is connected to the hub by means of flat springs rigidly mounted on the intake valves camshaft (9).

EFFECT: technical result consists in the device design simplification, changing the intake valves opening phases and in increase in the ICE gas-distribution mechanism reliability.
