Abstract
The present disclosure relates to the field of electromechanics. The teachings may be applied to high-pressure valves, including methods for operating a valve and with devices which are used for activating the valves. Some embodiments include methods for operating a pressure reduction valve for an accumulator injection system, wherein the valve is driven, against a return spring, with an energizable coil and armature, between a closed position and an open position. The method may include: supplying the coil with a defined electrical signal to move the armature, sensing the current intensity profile over time, and determining a movement profile for the defined current signal, including an opening or closing time, based at least in part on the current intensity profile over time.
