Abstract (en)
[origin: WO2013092169A1] The invention relates to an apparatus for driving an electrically operable valve which has a valve coil (1a, 1b), comprising: a main switch (5a, 5b), which is arranged in the electrical circuit of the valve coil (1a, 1b), for setting the current flowing through the valve coil (1a, 1b), and a freewheeling path (6a, 6b) which is connected parallel to the valve coil (1a, 1b) and has a freewheeling diode (3a, 3b). The invention provides a freewheeling switch (2a, 2b) by means of which the freewheeling path (6a, 6b) can be interrupted or closed. As a result, it is possible to operate the valve selectively in a PWM mode or in a switching mode.
