ABSTRACT:
The invention relates to an intake or exhaust valve mechanism with a variable valve opening cross section for use in an admission opening of an internal combustion engine and having a gas exchange valve acted on by the force of a valve spring and displaceable axially back and forth inside a guide by a valve control unit; the position of the sealing slide relative to the gas exchange valve in the axial direction is continuously variable by means of an adjusting unit. A sealing slide is disposed coaxially to the gas exchange valve, is acted upon by the force of a coupling spring, and is displaceable axially back and forth by the valve control unit.
