Abstract
The fluid pump has an impeller ( ), provided with vanes ( ) and driven to rotate in a pump chamber. The pump chamber is defined in the direction of the pivot axis ( ) of the impeller ( ) by wall parts ( ), in each end face ( ) of which toward the impeller ( ) there is one annular feed conduit ( ). An intake opening discharges in the region of the beginning of the feed conduit of one wall part, and an outlet opening ( ) discharges in the region of the end of the feed conduit ( ) of the other wall part ( ). The outlet opening ( ) is embodied as elongated in the circulation direction ( ) of the impeller ( ), and in the radial direction with respect to the pivot axis ( ) of the impeller ( ), it has a width (b) that is less than the width (B) of the feed conduit ( ) in the radial direction. Instead of the elongated outlet opening ( ), it is also possible for a plurality of separate outlet openings to be provided, which are offset from one another in the circulation direction ( ) of the impeller ( ).
