冷却液ポンプ
Document Type and Number:
Japanese Patent JP2013545021
Kind Code:
A
Abstract:
An axial-flow coolant pump mechanically driven by a pulley, a gear wheel, a plug-in shaft, or the like, for internal combustion engines uses a semi-axial impeller, a Francis impeller or diagonal impeller with three-dimensionally, spatially curved blades as the rotor, and the stator disposed in the pump housing possesses an inner guide cone that narrows in the flow direction, and an outer conical guide cap disposed to be spaced apart from the cone, and the two, spaced apart symmetrically, are connected by way of three-dimensionally, spatially curved stator vanes, wherein the rotor is spaced apart from the stator by a ring gap, in such a manner that the rotor has a minimal distance, not only, on the face side, from the adjacent outer edge of the guide cone, but also, on the face side, from the adjacent outer edge of the guide cap.
