CAM SYSTEM WITH ADJUSTABLE POSITION Russian patent published in 2022 - IPC F01L13/00 F01L1/47 

FIELD: engine building.

SUBSTANCE: invention can be used in internal combustion engines. Cam system (11) with an adjustable position for an internal combustion engine is proposed. Cam system (11) with an adjustable position includes camshaft (12) and a group of bases (14) for cams, with at least two cams (32, 34) each, wherein groups of bases (14) are mounted on camshaft (12) without the possibility of rotation, but with the possibility of displacement along the axis. Cam system (11) with an adjustable position includes a group of fluid-controlled actuators (27, 127, 227, 327, 427, 527), each of which is designed to displace along the axis one base (14) for cams of the group of bases (14). Cam system (11) with an adjustable position includes working fluid supply device (66) connected upstream by means of fluid to groups of actuators (27, 127, 227, 327, 427, 527) to actuate the group of actuators (27, 127, 227, 327, 427, 527). At least two actuators of the group of actuators (27, 127, 227, 327, 427, 527) are interconnected by fluid for simultaneous actuation.

EFFECT: possibility of simultaneous actuation of two actuators by supplying working fluid, reduction in labor intensity of control of a controlled valve drive.
