Definitions

  • the invention relates to a pump device for use as a pump, as a compressor or as a generator.
  • Pump devices are used in many areas of industry. For example, pump devices are used as fuel pumps in motor vehicles.
  • a pump device often used as a fuel pump is a so-called wobble pump, in which a pump rotor positioned at an angle on a pump shaft is set in a swiveling or tumbling motion by rotating the pump shaft relative to a rotor housing, so that pump chambers formed between the pump rotor and the rotor housing with regard to their volume can be varied.
  • these pump chambers are connected to an inlet and an outlet.
  • the pump device can be exposed to mechanical loads, which can require a complex structure of a housing of the pump device in order to be able to ensure sufficient stability of the housing.
  • a robust pump device can be provided which, in particular, can be designed in a simplified manner with regard to the structure of a housing. Due to the simplified structure of the housing, the Pump device can also be designed compact in an advantageous manner with respect to a circumference.
  • the invention relates to a pump device for conveying a medium, in particular a gaseous and / or liquid medium.

  • the pump device as a whole can be provided in a compact manner, in particular in a compact manner with regard to a circumference or with regard to an outer diameter.
  • the lack of the additional housing sleeve can have an advantageous effect on cooling the pump device, since it can be cooled directly. Stresses in components of the housing, which can occur due to different coefficients of thermal expansion of the housing sleeve and the housing part, can also be avoided.
  • the lack of the additional housing sleeve also avoids static overdetermination of components, for example in the flanging process, the assembly of the pump device can be simplified, additional corrosion protection of the housing sleeve can be omitted and savings in logistics and maintenance of the pump device can be achieved.
  • components of the pump device in particular components inside the pump device, are damaged and / or deformed during production, which can reduce rejects in production.
