Definitions

  • the invention has for its object to provide a circuit arrangement for controlling an electromagnet of a directional control valve, which enables the soft switching on and off of this directional control valve, takes up a small amount of space and is economical to manufacture.
  • the solution to the problem is that one pole of the power supply line is connected to the electromagnet via a transistor of the "Power MOSFET" type, that the control line of the transistor contains a first resistor which can be connected to the other pole of the power supply line, un that the control line is connected to the first pole of the power supply line via a capacitor.
  • the switching time until the nominal voltage is reached can be set to a desired value, which is between 100 ms and 500 ms, but can also be seconds.
  • the control voltage does not increase linearly, but approximately according to an e-function with negative exponents, but this is sufficient for many applications. Because of the small construction volume, the components can be accommodated in a cube connector, so that existing systems can be easily retrofitted.
  • the pole 10 When the pole 10 is set to 0 V, the voltage of the control electrode decreases analogously to an adjustable ramp, and the resistance of the transistor 4 increases. Accordingly, the current drop of the magnet 3 and thus also the magnetic force takes place.
