Abstract

See full text

A pulse-width-regulating valve is for the regulation of a fluid flow or a fluid pressure. The pulse-width-regulating valve comprises a cut-off valve connected in series with an inflow valve, at least one of the cut-off valve and the inflow valve being provided with an axially displaceable or rotatable valve element which has an opening position or a closing position at a distance from a starting position of the valve element. A method of operating a pulse-width-regulating valve comprises: regulating a valve gear device by a valve synchronizer, in accordance with at least two displacement curves; and by one or more valve actuators, displacing or rotating corresponding valve elements arranged in the pulse-width-regulating valve.
