Actuator with capacitive element e.g. for controlling fuel injection valves in IC engine, has Ohmic resistance connected in parallel with capacitive element dimensioned so that element discharges in time greater than maximum drive duration

摘要

The actuator has a capacitive element (100a), and the control parameter depends on the voltage applied to the capacitive element and/or the drive duration of the control device. An Ohmic resistance (100b) connected in parallel with the capacitive element is dimensioned so that the capacitive element discharges within a discharge time greater than the maximum possible control device drive duration.
