ADJUSTABLE VALVE DRIVE FOR INTERNAL COMBUSTION ENGINE Russian patent published in 2021 - IPC F01L1/47 F01L1/18 

Abstract RU 2756493 C2

FIELD: internal combustion engines.

SUBSTANCE: adjustable valve drive (10) for an internal combustion engine includes camshaft (12), valve (18) of gas distribution mechanism (20) and base (22) for cams. Base (22) for cams is located on camshaft (12) without the possibility of rotation and with the possibility of movement along the axis, and it contains first cam (28) and second cam (30). There is force transmitting mechanism (16) with force transmitting element (40), in particular, swinging lever or rocker arm, which, depending on axial position of base (22) for cams, selectively establishes a kinematic connection between first cam (28) and valve (18) of gas distribution mechanism (20) or between second cam (30) and valve (18) of gas distribution mechanism (20). There is first executive element (24) installed for moving base (22) for cams along the axis. First executive element (24) is at least partially located in force transmitting mechanism (16). A vehicle with an adjustable valve drive is disclosed.

EFFECT: mounting space is optimized.
