Definitions

  • the invention relates to a motor pump unit in which an electric motor and a pump are structurally combined with one another.
  • the rotor / stator of the motor envelops the pump.
  • EP 0 611 887 A1 describes a motor pump unit.
  • the rotor of the motor is an independent component, but is connected to the cylinder block of a piston pump in a rotationally fixed manner.
  • EP 0 103 357 B1 describes a motor pump unit in which the rotor of the electric motor is cup-shaped. The rotor is located between the motor stator and the pump. The rotor and pump are in gear connection with each other via a toothing.
  • This previously known unit has the great advantage that it has a minimal diameter.
  • the radial extent is therefore relatively small.
  • the invention has for its object to design a motor pump unit according to the preamble of claim 1 such that its axial dimension is reduced without having to increase its radial dimension, with constant motor output and with constant pump output.
  • the inventors have accordingly integrated subassemblies of the type mentioned into the housing of the unit, specifically in the region of the housing end wall. This allows a smaller axial installation space to be used without having to enlarge the radial installation space.
  • the motor pump unit comprises an electric motor 1 with a stator core 1.1, a winding 1.2 and a rotor 1.3.
  • the two elements motor and pump are enclosed by a common housing 3.
  • a common housing 3 In the housing 3 there is an inlet 3.4 between the rotor and stator for introducing coolant, and an outlet 3.5 axially from the pump.
  • the rotor 1.3 of the motor 1 is cup-shaped. In the present axial section it appears U-shaped.
  • the pinion shaft 2.3 is in rotary connection with the rotor 1.3 via a toothing.
  • Another drive connection could also be established between the rotor 1.3 of the motor 1 and the pinion shaft 2.3. So it is conceivable to provide not only a single, but two or more toothings with corresponding torque-transmitting elements between these two, so that a translation from the speed of the rotor to the pinion shaft takes place in slow or fast.
  • the rotor 1.3 is mounted on the pump 2, more precisely on the two side disks 2.4, 2.5.
  • the housing 3 comprises a cylindrical, sleeve-shaped part 3.1, a side window 3.2, which is located in the region of the web of the U, and a side window 3.3.
  • a supply line 3.4 and a discharge line 3.5 for the medium to be conveyed are incorporated into the side window 3.3.
  • the arrows illustrate the direction of flow of the medium between the rotor and stator of the electric motor 1 and through the pump 2.
  • the cylindrical part 3.1 of the housing is extended towards the web-side side window 3.2, so that a relatively large space 4 is created. This serves as an oil tank.
  • the side window 3.3 also contains a pressure relief valve 5 and also a directional valve 6.
  • the directional valve 6 is arranged in a block 3.3.1.
  • Block 3.3.1 is placed along a parting plane 3.4 on the main part of the side window 3.3 and firmly connected to this main part, for example by screwing. In the assembled state - as shown here, the lines of the block 3.3.1 and the main part of the side window 3.3 are aligned so that they are in a conductive connection with each other.
