Actuator for vol. control valve for direct injection IC engine, with valve controlling pressure build-up is pressure storage

摘要

The vol. control valve is earthed via a switch and a valve terminal is connectable to an energy storage, such as a booster capacitor or a capacitor of a DC/DC converter. On the switch opening, the released energy in the energy storage is recharged. The vol. control valve is connectable to supply voltage via a second switch, while a third switch provides the connection of the vol. control valve to the booster capacitor. The DC/DC converter and/or the booster capacitor may be used for voltage supply of further consumer appliances.
