Abstract (en)
[origin: US4291358A] The magnetic valve with electronic control for increasing the attractive output has an energizing coil (AE), which is supplied in the attracting phase with an increased energizing current via a closed switch (T2). In the maintenance phase, the energizing coil (AE) is supplied with a maintenance current, via a compensating resistor (RV) and with the switch (T2) opened, which is lower than the energizing current. For the purpose of controlling the switch (T2), a timing circuit is provided which includes a resistor (R2) and a capacitor (C2). The magnetic valve is selectively drivable with alternating current or direct current. A portion of the energizing coil (AE) is made up of the compensating resistor (RV), which is embodied as a resistor wire and wound up on the energizing coil (AE).
