Title:
圧送ポンプ
Document Type and Number:
Japanese Patent JP4741155
Kind Code:
B2
Abstract:
The pump has two crowns of blades (13, 14) located concentrically in a rotor (4). The angles (alpha 2-alpha 3) of the blades of the radially outer crown to the perpendicular are greater than the angle (alpha 1) of the blades of the radially inner crown. Because of this, the rotor can be produced cheaply by injection molding.
