ADJUSTABLE VALVE MECHANISM AND CAR WITH SUCH MECHANISM Russian patent published in 2022 - IPC F01L1/04 F01L1/18 

FIELD: physics.

SUBSTANCE: invention concerns an adjustable valve mechanism (10) for an internal combustion engine. The adjustable valve mechanism (10) has at least one lifting valve (16), in particular a gas distribution valve and a cam shaft (12), which has a first cam (18) and a second cam (20) located with a shift in the longitudinal direction of the cam shaft (12). The cam contour of the first cam (18) differs from the cam contour of the second cam (20), and/or the first cam (18) and the second cam (20) are located with a shift in the circumferential direction around the longitudinal axis of the cam shaft (12). The adjustable valve mechanism (10) also has a transfer lever (14), which is located in an active connection between the specified at least one lifting valve (16) and the camshaft (12) to actuate the specified at least one lifting valve (16). The transfer lever (14) has an axis (22) of rotation, a mount (26) and a cam follower (28). The mount (26) is installed with the possibility of rotation around the axis (22) of rotation. The mount (26) holds the tracking element (28) of the cam. The mount (26) is installed with the possibility of axial displacement parallel to the axis (22) of rotation and/or parallel to the cam shaft (12), so that the cam follower (28) selectively follows the cam contour of the first cam (18) or the cam contour of the second cam (20). The transfer lever (14) has a bearing component (24), which is installed with the possibility of rotation around the axis (22) of rotation. The bearing component (24) supports the mount (26) with the possibility of axial displacement, and at the same time the specified mount (26) partially covers the bearing component (24).

EFFECT: proposed is a new adjustable valve mechanism and car with such mechanism.
