ADJUSTABLE VALVE DRIVE Russian patent published in 2022 - IPC F01L1/18 F01L13/06 

FIELD: engine building.

SUBSTANCE: invention can be used in internal combustion engines. An adjustable valve drive with a system of cams with an adjustable position for an internal combustion engine includes a shaft, a base for cams, mounted on the shaft without the possibility of rotation and with the possibility of axial displacement, first actuator (24), and second actuator (26). The base for cams contains the first cam, the second cam, first working section (32), second working section (34), and third working section (36). First actuator (24) is made with the possibility of movement of the base for cams in the first axial direction and engagement with first working section (32). Second actuator (26) is made with the possibility of movement of the base for cams in the second axial direction opposite to the first axial direction and engagement with second working section (34), and with the possibility of movement of the base for cams in the first axial direction and engagement with third working section (36). A vehicle is disclosed.

EFFECT: provision, during failure of an actuator, of the possibility of axial movement of a cam with an adjustable position along an axial movement trajectory set for the failed actuator.
