- a pump body (2) which is accommodated in the housing and rotatable around an axis (12), wherein the pump body (2) comprises at least one spiral channel,
wherein a first outer end (8a, 8b, 8c) of the at least one spiral channel is located on an outer side of the pump body and forms an entrance opening for alternately taking in water and air through rotation of the pump body in the housing, and a second outer end of the at least one spiral channel debouches into an outlet (10) close to the axis, wherein the housing is embodied as pressure chamber. |
