Abstract:
1. A stroke-transmitting device for a variable transmission of strokes to a means to be actuated, in particular for the variable transmission of a camshaft stroke to a gas-exchange valve ( 10 ) of an internal combustion engine, comprising a control unit having a first control means ( 11 ) and at least a second control means ( 12 ), at least one control cam ( 13 , 14 , 15 , 16 ) coupling the first and second control means ( 11 , 12 ) with contact regions ( 14 , 34 ) and being displaceable relative to one another in a contact region of the control cam ( 13 , 14 , 15 , 16 ) in at least one first degree of freedom ( 17 ) for a constant adjustment of the stroke, the first and second control means ( 11 , 12 ) being axially displaceable relative to one another, and the first control means ( 11 ) being additionally also rotatable about its longitudinal axis ( 19 ) so as to provide for at least one second degree of freedom ( 18 ) differing from the first degree of freedom ( 17 ) in a contact region of the control cam ( 13 , 14 , 15 , 16 ) in order to adjust the stroke.
