Definitions

  • the invention is directed to a regulable coolant pump for a cooling circuit of an internal combustion engine.
  • U.S. Pat. No. 1,813,747 A is a radial pump wherein the volumetric delivery can be regulated by means of a slide, which is disposed on the impeller and is displaceable in the axial direction.
  • the regulation of the slide between an open position and a closed position is effected by turning a thread-type guide, which adjusts the slide axially.
  • the elastic sealing element is disposed in the greatest diameter region of the cover disk.
  • the sealing element is supported in a sealing manner on the baffle plate.
  • the sealing element is preferably realized as a multicomponent injection molded part.
  • a highly elastic, wear resistant plastic is preferably provided as material for the sealing element.
  • the invention includes a reinforced sealing element, wherein the reinforcement is, for example, pressed into a groove of the cover disk and vulcanized to a sealing material.
