Abstract (en)
[origin: WO0161156A1] The invention relates to a method and a circuit arrangement for operating a solenoid valve (MV), especially for actuating an electrohydraulic gas exchange valve gear, an injection valve or an inlet or outlet valve of an internal combustion engine. The aim of the invention is to enable the solenoid valve (MV) to be controlled as simply as possible. The solenoid valve (MV) is impinged upon in a controlled manner and in a cycle that comprises three phases. The solenoid valve (MV) is connected to a first voltage (U_1) for a predetermined period (T_1) during a pick-up phase for producing a pick-up current, whereby said voltage has a predetermined value. Said solenoid valve (MV) is connected to a second voltage (U_2) in a holding phase for producing a holding current, whereby said voltage has a predetermined value. Said valve is separated from the two voltages (U_1, U_2) in a switching-off phase.
