Abstract
The valve drive mechanism is particularly suitable for internal combustion engines of motor vehicles. The mechanism has at least one driven cam element and a valve control member which is moved (translationally or rotationally) by the cam element. The cam element is rotatingly mounted in a flexible surround element which is connected to the valve control member in a plane orthogonal to the axis of rotation of the cam element. The surround element can be reversably extended, such as elastically extended, to enable a variation in the resulting valve lift.
Claims35
A valve mechanism, comprising:
- at least one driven cam element and a valve actuator driven by said cam element;
- a flexible surround element, said cam element being rotatably disposed in said flexible surround element about an axis of rotation and said flexible surround element being movably connected to said valve actuator for movement in a plane perpendicular to said axis of rotation of said cam element, and wherein said surround element is configured to be reversibly lengthened for adjusting a valve lift of said valve actuator.
