  • components can be included in the system switching components such as valves and sensors that are used for control and control supply important parameters, be integrated. When assembling the individual components becomes a work step, namely that of contacting, saved, which makes work considerably easier.
  • A can be used as the basic module of the modular system according to the invention electronically controlled pump, which have its own in a separate Electronic housing housed control electronics.
  • the control electronics advantageously comprises one in addition to the semiconductor components independent microprocessor that can be used for control tasks.
  • This microprocessor can receive information via the electrical interface from external sensors installed in the components or control signals can be sent to the components.
  • the one in the pump previously existing microprocessor can thus be used for any other task Components are used, which leads to a saving in intelligent Leads components in these other components.
  • electrical Interface can also supply power to the hydraulic Components of attached electric drives can be accomplished.
  • Control electronics for the pump housing is initially as Interface trained electrical connector provided through the one electrical or electronic component connected to the pump housing, For example, a sensor located in or on the pump housing with which Control electronics of the pump motor can be connected. The connector will be there automatically when the components of the pump housing and Electronics housing created.
  • the pump housing has the Base facing away from the motor has an electrical interface with other external components can be connected.
  • This interface can be in Combination with the interface between the electronics housing and the Pump housing can be provided, advantageously both Interfaces via a line running inside the pump housing are connected.
  • This "external" interface attached to the pump housing can also be contacted directly with the control electronics.
  • the pump housing advantageously has a suction nozzle and a Pressure port on, both in a perpendicular to the axis of rotation of the impeller aligned and forming the hydraulic interface end wall of the Pump housing are introduced, the suction port coaxial with the impeller is arranged.
  • These types of pumps are suitable for the use of electro-hydraulic Interface especially because the individual components are on simply and stably stacked in the axial direction and can be screwed together.
  • the connectors are connected to the hydraulic interfaces only sockets (female contacts) are provided, whereby two meeting female contacts by means of a double plug (Double-male contact).
  • sockets female contacts
  • Double-male contact two meeting female contacts by means of a double plug
  • the Contacting is not necessary, but must be done by inserting the double-male contact getting produced.
  • the live contacts in particular those of the Control electronics laxative contacts- are designed to be female contacts minimize the risk of short circuits and electric shocks.
  • the pump housing that on the side facing the electric motor, in particular by means of a Male contact with the electronics housing contacted on the motor facing away from a second, in particular shaped as a female contact Plug contact for contacting a placed on the pump housing hydraulic component to be supplied electrically, for example a electrically switchable valve or a sensor. It is advantageous the first contact with the second contact through one in the pump housing extending line, in particular a plugged into the housing or from Housing molded sheet metal is connected. That way it can Pump housing serve as an electrical connection to other components.
  • the electrical interface can generally comprise several lines that either, as is usual with data buses, a small cross-section and / or that for Power line have a correspondingly larger cross section. From the through the housing of a component can pass through lines according to the needs of individual lines in the respective component be branched off.
  • Multi-way valves with a valve housing that includes a valve body surrounds and two parallel to each other corresponding to the pump housing Has bases with connection openings made therein, each Base area forms a hydraulic interface.
  • Multi-way - especially three-way valves can be with the corresponding Combine openings in any way with other components while the electrical drive of the valve can be controlled via the electrical interface, i.e. can be supplied with tax information and electricity.
