VALVE GAS CONTROL MECHANISM FOR VALVE-CONTROLLED INTERNAL COMBUSTION ENGINE Russian patent published in 2017 - IPC F01L1/02 F02B67/04 F16H55/18 

FIELD: engines and pumps.

SUBSTANCE: valve gas control mechanism is designed for an internal combustion engine. At least one camshaft of the engine is installed in the engine cylinder head and driven by cylindrical gearwheels. The driving cylindrical gearwheel is placed on the crankshaft installed in the engine cylinder block. The driven cylindrical gearwheel is located on the camshaft. There is at least one adjustable intermediate gear installed on a trunnion (13). The trunnion (13) for the intermediate gear is designed to lock in at least two positions on the end face (9a) of the internal combustion engine. The above mentioned positions correspond to the new state of the engine and specified repair state of the engine with purposefully changed distances between the axes of the crankshaft and camshaft. There are channels (16), (18) for lubrication oil open to the end face (9a) and provided on the end face (9a). The channels, being in one position or another of the intermediate gearwheel, are located coaxially with the lubrication oil channel in the trunnion (13) of the intermediate gearwheel. The lubrication oil channels (16), (18) are oriented in such a way that the trunnion (13), in one or the other position, closes one corresponding channel of the channels (16), (18) for lubrication oil.

EFFECT: simplified manufacture and assembly of the valve gas control mechanism.
