  • control device includes for generating energy, for example, an air pressure transducer with electric generator. This is constantly connected to the pressure line, which has a constant air consumption, even if the energy storage has sufficient memory content. Due to the continuous operation, it is even suggested to completely renounce the energy storage. Its state of charge thus depends on the operation of the other components and is more or less random.
  • An object of the present invention is to improve the known control device and a corresponding electrical supply module so that the air consumption is minimized despite sufficient power supply.
  • control device The advantages of the control device according to the invention are, in particular, that the air pressure transducer for the charge control valve is only switched on when this is necessary for the energy supply.

  • the charge control device By the charge control device, the state of charge of the energy storage can be completely detected.
  • the entire control device has the further particular advantage that it only has to be connected to a fluidic line. All electrical supply and control lines can be omitted. It is therefore particularly suitable for use in spatially widely distributed systems, such as process equipment, where enormous installation costs can be saved.

In this case, the input valve 17 can be omitted, and the charge control valve 23 is closed during the backflow of the fluid from the actuator 10.
  • the execution of the working valve 18 depends not least on the control requirements for the actuator 10, that is, how many control paths the working valve 18 must have.
