FLUID PUMP
Document Type and Number:
WIPO Patent Application WO/2011/028113
Kind Code:
A3
Abstract:
The invention relates to a fluid pump with a rotation- symmetrical pump housing, a rotatably drivable shaft extending coaxially thereto, at least three blades extending radially from the shaft, at least one supply opening arranged in a pump housing wall and at least one discharge opening arranged in a pump housing wall, wherein the supply opening extends over a first arcuate part and the discharge opening extends over a second arcuate part, wherein the second arcuate part lies outside the first arcuate part, and blade displacing means are arranged for the purpose of increasing the distance between adjacent blades at the position of the supply opening and for reducing the distance between adjacent blades at the position of the discharge opening. This pump is a displacement pump. Fluid is here suctioned into a space between two blades because the volume between these blades is increased. Fluid is forced out when the space between the blades is reduced.
