Definitions

• compressed air supply facilities are of central importance.
• the braking system of a pneumatically braked commercial vehicle requires compressed air, as well as numerous other consumers, such as air suspension or Liftachs Schaum.
• the compressed air to be processed and distributed by the compressed air supply device is supplied by a compressor which generally driven by the internal combustion engine of the commercial vehicle.
• a common concept in this regard provides for the compressor to be coupled to the internal combustion engine via a pneumatically switchable coupling, wherein the compressed air for the pneumatic control of the clutch is again taken from the compressed air supply device.
• An example of such a device is given in DE 39 23 882 C2.
• Pressure value reaches a predetermined cut-off pressure and the humidity value is below the predetermined threshold.
• the conventional pressure control via the drain valve thus offers a replacement function for the primary pressure control via the switchable clutch.
• the electronic controller communicates via an interface with a controller integrated in a compressed air treatment system.
• the conventional electronic control of the compressed air treatment plant can remain largely unchanged, and the circuit functionality for the clutch can be externally available.
• Figure 1 is a schematic representation of a compressed air supply device according to the invention
• Figure 2 is a schematic representation of a compressed air supply device according to the invention.
• a 3/2-way valve 18 is arranged, which in the present case, as once again shown separately, is designed as an electrically pilot operated pneumatic valve.
• the pneumatic valve 18 has an input port 110 to which a leading to the coupling port 80 line 112 is connected.
• a check valve 40 is arranged, that a flow from
• FIG. 3 shows a schematic representation of a compressed air supply device according to the invention.
• the compressed air supply device shown here is shown in the form of several distributed individual modules.
• a pressure regulator 130 with attached filter unit 48, a multi-circuit protection valve 132, pressure limiter 134, 136 and an electronic control 38 are shown.
• the components may actually be distributed in the manner described.
• the distributed representation can also be understood in the sense of a functional division, wherein real pressure regulator, multi-circuit protection valve, the pressure limiter and / or the electronic control are realized integrated, for example as shown in connection with FIGS. 1 and 2.
• Output of the signal 16 may now be on the basis that pressures, temperatures or speeds measured by sensors may require opening the clutch 12. In parallel, the opening of the clutch but also on the basis of the issued by the pressure switch 24
