Abstract
A pump or turbine is disclosed which includes a housing provided with at least one chamber, a rotor, which is rotatably mounted on a shaft in the chamber, an inlet, which communicates with the chamber at least at the location of the shaft, and an outlet channel, which communicates with the chamber at least at the periphery of the rotor. The pump or turbine moreover comprises at least one bypass channel, a first end of which opens into the outlet channel of the pump and a second end of which forms an inlet. The bypass channel may be used for increasing the propelling force or for pumping slurries, for example.

A pump comprising:
- a housing comprising:
- a chamber,
- a rotor which is rotatably mounted on a shaft in the chamber,
- an inlet which communicates with the chamber at the location of the shaft,
- an additional chamber,
- an additional rotor which is rotatably mounted on an additional shaft in the additional chamber,
- a common outlet channel, which communicates with the chamber at the periphery of the rotor and communicates with the additional chamber at the periphery of the additional rotor, and a tangential bypass channel, a first end of which opens into the common outlet channel of the pump and a second end of which forms an inlet.
