VALVE-TIMING MECHANISM OF INTERNAL COMBUSTION ENGINE WITH HYDRAULIC VALVE OPERATING MECHANISM AND VALVE-TIMING HYDRAULIC SYSTEM OF INTERNAL COMBUSTION ENGINE WITH HYDRAULIC VALVE OPERATING MECHANISM Russian patent published in 2006 - IPC F01L9/02 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed valve-timing mechanism contains oil pump, valve operating cylinders coupled with engine valves and with spool distributor with housing, shaft, rotor with oil pass channels, upper frame with oil line unions, and lower frame with oil inlet-outlet unions. Frames are fixed in housing. Engine crankshaft sets into rotation shaft with fitted-on rotor through gear wheel by means of belt. Shaft is provided with straight and skew splines and screw cut and is installed in housing on bearings for rotation and axial displacement. Rotor is provided with opposite skew splines in connection with shaft, and gear wheel is connected with shaft by spline joint. Electric motor is coupled with shaft by screw cut. Spool distributor is provided both in circuit of operating mechanism of intake valves and in circuit of operating mechanism of exhaust valves.

EFFECT: simplified design, enlarged operating capabilities of engine.
