ADJUSTABLE VALVE MECHANISM HAVING ROCKER Russian patent published in 2020 - IPC F01L1/18 F02D13/02 

FIELD: engine building.

SUBSTANCE: invention can be used in the internal combustion engines. Adjustable valve mechanism (1) for lifting valve includes cam shaft (7), having at least one first cam (3) and at least one cam (4), (5) located offset from cam shaft (7) longitudinally. Valve mechanism (1) includes rocker arm (10), roller lever (20) and switchable hydraulic locking device. First cam (3) and second cam (4), (5) differ in cam shape. Rocker 10 is arranged to turn about yoke axis 2. Rocker arm (10) by its shoulder (11) facing the cam shaft by means of roller (13) is matched with the said at least one first cam (3), and its arm (12) facing the valve is in active connection with at least one lifting valve. Roller lever (20), which by its shoulder camshaft (21) by means of at least one roller (23) is matched with said at least one second cam (4), (5), and its other arm is hingedly connected to rocker (10) with possibility of rotation about yoke axis (2). By means of switchable hydraulic locking device, rocker arm (10) and roller lever (20) alternately can be rigidly interlocked with each other, note here that rocker arm and roller lever follow movement of said at least one second cam (4), (5). By means of switchable hydraulic locking device, rocker arm (10) and roller lever (20) can be alternately unlocked with each other, wherein both independently of each other follow matched cams (3), (4), (5), respectively. Roller lever (20) is connected with rocker arm (10) by means of hinge (14), (24), (25), and/or rocker arm (10) and roller lever (20) have hinge seat (14), (24) pin, which are coaxial to each other and have inserted hinged pin (25). Disclosed is a car having a valve mechanism.

EFFECT: technical result consists in improvement of compactness and simplification of installation of valve mechanism.
