<P>PROBLEM TO BE SOLVED: To provide a fluid rotary wheel which has simple shape and excellent rigidity and can force fluid on the back of the blade to move forward at the front by small power through the utilization of a change in fluid pressure on a surface of the blade. <P>SOLUTION: In a rotor 1 for fluid equipment in which the peripheral surface of a hub is projectingly provided with a plurality of blades 3 directed in a radial direction, the front 3D having a wing end of each of the blades 3 directed upward is formed to be a flat face with a wing thickness of a part close to a front edge 3A in a chord direction maximized in the back 3F and a rear edge 3B thinned down to form a curved surface. In a side view, the front 3D is made perpendicular so that the wing thickness is gradually reduced toward a wing end from a wing root. <P>COPYRIGHT: (C)2013,JPO&INPIT |
