Abstract

A method and apparatus for starting and regulating valve systems for displacement-type machines such as fuel-regulated internal combustion engines wherein a valve can be held in at least two final operational positions. The valve systems are each designed as an oscillating spring/mass system such that periodic force components or travel path excitations can be communicated to the spring/mass system in its original starting position or in a static home position. The pulse characteristics or frequency of the force components or excitations are close or equal to the natural frequency of each spring/mass valve system, so that the valve system is caused to oscillate with an increasing amplitude and is thus excited into one of the two final operational positions.
