FIELD: engines and pumps. ^ SUBSTANCE: ICE valve tuning device incorporates an aligned driving element linked with the engine crankshaft and a camshaft linked via a phase adjustment ICE valve timing device engaged with the engine crankshaft, and a camshaft tied by a centrifugal phase adjuster furnished with an assembly of transmitting a control force on to the aforesaid cam shaft, the said assembly being made as a gearing. The said gearing incorporates a worm gear rigidly fitted on the camshaft and making an engagement with, at least, two worms, everyone of which rigidly supports centrifugal levers and return springs. Here, note that the latter are designed to interact with the aforesaid levers. The worm wheel features the number of teeth corresponding to the number of worm screw, every tooth being made in the form of a rod, while every worm, made in the form of a cylinder with a slot, being arranged on the drive element to turn around its own axis. ^ EFFECT: higher efficiency, simpler design and ease of manufacture. ^ 4 dwg |
