Abstract (en)

[origin: EP1050669A2] The device is operating a valve with variable lift in an internal combustion engine. Two revolving and adjustable camshafts involved together with a valve activated by a closure spring, an axial tappet acting on the valve shaft end and an operating lev activated by both camshafts and affecting the cup tappet. The first camshaft (1) is arranged above the tappet (8) and is provided with an operating cam (4). The second camshaft (2) arranged above the first camshaft and is provided with an adjustment cam (13). The operating lever (14) is pivotably located at first end point (15) on the tappet and supports pivotably with the other end point (16) on a bearing (17) of a connecting part ( Centrally, the operating lever is in effective connection with the operating cam (4) of the first camshaft. The connecting part extends crossways between the two camshafts and supports a roller (22) at its end opposite to the bearing.
