Japanese Patent JP2003502580
Kind Code:
A
Abstract:
The fluid pump has an impeller (10), provided with vanes (12) and driven to rotate in a pump chamber. The pump chamber is defined in the direction of the pivot axis (18) of the impeller (10) by wall parts (24), in each end face (25) of which toward the impeller (10) there is one annular feed conduit (32). An intake opening discharges in the region of the beginning of the feed conduit of one wall part, and an outlet opening (34) discharges in the region of the end of the feed conduit (32) of the other wall part (24). The outlet opening (34) is embodied as elongated in the circulation direction (11) of the impeller (10), and in the radial direction with respect to the pivot axis (18) of the impeller (10), it has a width (b) that is less than the width (B) of the feed conduit (32) in the radial direction. Instead of the elongated outlet opening (34), it is also possible for a plurality of separate outlet openings to be provided, which are offset from one another in the circulation direction (11) of the impeller (10).
