Definitions

  • the invention relates to a device comprising one of one electronically controlled or regulated electric motor driven pump with a Pump control unit as well as one from an electronically controlled or regulated drive mechanism driven valve with a valve control unit.
  • valves of this type are, for example, from the motor vehicle sector known.
  • the valve is in particular a multi-way valve, which by a Linear drive or a rotary drive, for example one Rotary magnet, a stepper motor or a DC motor driven can be. Regardless of the type of drive mechanism of the valve Displacement sensors are provided to ensure exact positioning of the valve body guarantee.
  • both the pump and the Valve each have their own control unit, in particular a Power electronics, a processor and a communication module exhibit. Both control units are via the communication module preferably by means of a data bus to a separate or higher-level one Control device can be connected.
  • This Hydraulic device comprises a driven by a three-phase motor Control pump that can be controlled via a control element.
  • the speed of the engine is regulated by a frequency controller, the corresponding instructions received from a controller.
  • the hydraulic device further comprises a valve, via a control unit separate from the control element of the pump is controllable. Communication between the frequency controller of the motor of the Pump on the one hand and the control of the valve on the other hand takes place via the controller. In this hydraulic device there is an additional one Communication with other external components is not provided.
  • both the control unit of the pump and the control unit should communicate with such external components, for example for external control or setting of temperature specifications, Valve setting values or for the transfer of diagnostic functions, see above Both control units require one communication module each.
  • the two control units mean in particular due to of the respective communication modules not only a large space requirement and high costs, but also the connection of the two control units considerable assembly effort and involves an additional risk of error. Also plugs or connectors as well as cables are in accordingly large number or length required.
  • the object of the present invention is therefore to provide a structurally simple, inexpensive to manufacture and easy to use device of the beginning to create the type mentioned, with small external dimensions and small Weight is quick and easy to assemble and connect. In doing so as few connections as possible and the shortest possible cable runs required his.
  • valve control unit completely or is partially integrated into the pump control unit.
  • the main advantage is that at least individual components of the Valve control unit can be saved. The functions of the saved Components are then removed from the pump control unit accepted. This leads to a reduction in that for the valve or for the valve control unit required space and in particular to one less effort in the assembly and connection of the device. Possible sources of error are reduced to a minimum. That too is In this way, the device can be produced and closed particularly cost-effectively assemble.
  • modules in the pump control unit and / or components are provided such that some or all Valve control functions performed by the pump control unit can be.
  • the pump electric motor driving a pump control unit with power electronics, a processor and a communication module for the Has communication with a separate control device, and in which the the drive mechanism driving the valve via a communication module and in particular via power electronics to the separate control device is connected it is proposed that at least that Communication module of the drive mechanism of the valve in the pump control unit is integrated.
  • the communication module is the largest part of the Control unit, so that the saving in the required space here greatest is.
  • the space requirement of the valve can be further reduced by the Drive mechanism of the valve is controlled by a processor that is in the Pump control unit is integrated.
  • the space requirement of the valve can also be reduced in that the Power electronics of the drive mechanism of the valve in the control unit of the electric motor is integrated.
  • the power electronics the drive mechanism of the valve via an evaluation unit Evaluation of the values determined by at least one sensor Pump pumped liquid controlled.
  • the sensor (s) can the temperature and / or the flow and / or the pressure of the conveyed Determine liquid.
  • valve is directly connected to the pump connected or integrated into the pump. In this way the Effort for assembly and connection of the invention Device reduced to a minimum. There are only a few plug connections and particularly few or short cables are required.
  • the device can be accommodated in a confined space and is modular be constructed.
  • the pump also helps the electric motor and the control unit together with the valve and the Drive mechanism and optionally with the at least one sensor a module or a unit.
  • This module or unit can be particularly fast and simply via at least two hydraulic interfaces on one Liquid circulation system and at least one electrical interface can be connected to the separate control device.
  • the liquid circulation system can preferably be the cooling circuit the internal combustion engine of a motor vehicle or the heating water circuit a heating system.
  • FIG. 1 corresponds to the previously known devices that comprise a pump 1 and a valve 2.
  • the valve 2 is shown in the Example a three-way valve, but the invention is also fundamentally can be used with any other type of valve.
  • the pump 1 is from an electronically controlled electric motor 3 driven, controlled or regulated by a pump control unit 4 becomes.
  • the pump control unit 4 has power electronics 5, one Processor 6 and a communication module 7 for communication with a separate control device 8.
  • the pump control unit is via a data bus 9 4 connected to the higher-level control device 8.
  • the valve 2 is from an electronically controlled drive mechanism 10 driven, which is controlled or regulated by a valve control unit 11.
  • the drive mechanism 10 is one in the illustrated examples Stepper motor, but other drive means are also used can.
  • the valve control unit has 11 a power electronics 12, a processor 13 and its own Communication module 14 for communication with the separate control device 8 on.
  • the valve control unit 11 is a second Data bus 15 connected to the higher-level control device 8.
  • FIGS. 2 to 4 is at least the function of the communication module 14 of the valve control unit 11 integrated into the pump control unit 4.
  • the communication module 7 of the pump control unit 4 takes over both the communication the pump control unit 4 as well as the communication of the valve control unit 11 with the separate control device 8.
  • the drive mechanism 10 of the valve 2 ( Figure 4) and any further components of the valve control unit that may be provided 11 are only about a simple and relative inexpensive control connection 16 connected to the pump control unit 4.
  • the Power electronics 12 of the valve control unit 11 an evaluation unit 17th assigned with which the temperature values determined by two sensors 18 Liquid conveyed by pump 1 is evaluated and in the valve control unit 11 can be used to control the valve 2.
  • the Power electronics 12 of the valve control unit 11 an evaluation unit 17th assigned with which the temperature values determined by two sensors 18 Liquid conveyed by pump 1 is evaluated and in the valve control unit 11 can be used to control the valve 2.
