DEVICE FOR CORRECTING ANGULAR POSITION OF THE CAM SHAFT OF INTERNAL COMBUSTION ENGINE Russian patent published in 2019 - IPC F01L1/34 F02D13/02 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in the internal combustion engines. Device for correction of angular position of cam shaft of internal combustion engine includes coaxially arranged plate (1), driving (2) and driven (3) elements of kinematic chain of torque transmission from crankshaft to cam shaft (3). Driving (2) and driven (3) element are interconnected by two dynamically balanced centrifugal mechanisms and mounted on plate (1). Each centrifugal mechanism comprises lever (4). Lever (4) is connected to centrifugal mass. Plate (1) is rigidly connected to driven element (3). Each mounted on the plate centrifugal mechanism comprises double-arm lever (4). One arm of double-arm lever (4) is connected to driving element (2) by means of gear (5) or forging engagement or flexible connection. Second arm is connected by means of flexible connection (7) with the least weight element (9) from the centrifugal mechanism active mass packet. All elements of active mass pack are installed with the possibility of movement along guides (10, 11) radially and rectilinearly. Value of movement of each element from active mass packet is limited by device (8) for consecutive termination of force interaction of element with flexible connection (7) starting from largest element by weight. Sum of masses of the package elements shall ensure the beginning of the device action at the specified angular speed of the cam shaft.

EFFECT: technical result consists in providing correction of angular position of cam shaft when changing speed mode of engine operation.
