Abstract (en)
[origin: WO03018967A1] The invention relates to a valve mechanism comprising a variable cross-section of a valve opening. Said valve mechanism is arranged on a flow opening of an internal combustion engine and comprises a gas exchange valve which is actuated by the force of a valve spring and can be displaced back and forth in the axial direction inside a guiding element by means of a valve control unit. The position of the sealing slide can be continuously adjusted in the axial direction in relation to the gas exchange valve by means of an adjustment unit. According to the invention, a sealing slide (10) is arranged coaxially in relation to the gas exchange valve (12). Said slide is actuated by the force of a coupler spring (24), and can be displaced back and forth in the axial direction by means of a valve control unit.
