| 摘要 |
The invention relates to an axial pump with centrally embedded propeller for conveying a hydraulic fluid. According to the invention, the pump has an electromagnetic drive unit (4) having a stator (2) and a rotor (3), where the stator (2) is fixedly attached to the casing of the pump (1) and the rotor (3) rotates in relation with the stator (2) about an axis of rotation (5), where at least one conveying blade (7) is attached on an internal circumferencial part (6) of the rotor (3) to engage the hydraulic fluid in a conveying state, where the said at least one conveying blade (7) is configured so that a flow opening (9) radially cut inside the blade (7) crosses the rotor (3) in the axial direction of the rotation axis (5). |
