摘要： A control circuit for supplying a load with current having a high-amplitudeortion with a rapid leading edge, and a lower-amplitude portion. The circuit is input-connected to a low-voltage supply source, and comprises a number of actuator circuits parallel-connected between the input terminals and each including a capacitor and a load. Each actuator circuit also comprises a first controlled switch between the respective load and a reference line, for enabling energy supply and storage by the respective load. A second controlled switch is provided between the capacitor line and the load line, for rapidly discharging the capacitors into the load selected by the first switch and recirculating the load current, or for charging the capacitors with the recirculated load current.

摘要： The device includes a solenoid valve having a supply conduit communicating with the delivery of the pump, a drain conduit, an electromagnet energizable to control an armature controlling a shutter, and reducing means for reducing disturbance in the delivery pressure of the pump when the electromagnet is energized. The reducing means include a chamber having a predetermined volume and located between the supply conduit and the drain conduit; and a fixed shield having an opening in which slides a small-diameter portion of the stem of the armature. The electromagnet is controlled by an electronic unit via a modulator for modulating the duty cycle of the control pulses, and via a circuit for selecting the frequency of the control pulses on the basis of an estimate of hydraulic disturbances depending on at least one operating parameter.
