Turbo pump and supply system with a pump.

摘要

In a turbo pump according to the present invention, blades 3e and a shroud 3f are continuously formed with a boss 3c of a turbine wheel 3, a meridian plane configuration of the shroud 3f is formed as an concave arcing rotatable surface. A boss shroud 3f1 is formed substantially parallel to the axis of rotation O. A portion 3e2 of a blade outlet edge 3e1 is smoothly continuous to the boss shroud 3f1 and largely projects downstream. A portion 3e3 of the blade outlet edge 3e1 is formed substantially perpendicular to the axis of rotation O. The blade outlet edge 3e1 is formed with a smooth arc-like curve projecting convexly downstream between the portion 3e3 and the portion 3e2. An angle of the blade outlet edge 3e1 is set to an angle of substantially 0 DEG at the portion 3e2 of the blade outlet edge 3e1 and to substantially the conventional degree of angle at the portion 3e3 of the blade outlet edge 3e1. Further, the blade inlet 3a and the blade outlet 3b are connected there between by a curve. <IMAGE>
