Title:

FLUID FLOW ENGINE OR WIND MILL WITH AUTOMATICALLY ADJUSTABLE SCREW FAN

Document Type and Number:

Japanese Patent JPS5364139

Kind Code:

A

Abstract:

The rotary fluid flow engine, partic. wind powered, with automatically varying blade pitch angle comprises a hub (2) free to rotate on a shaft (3) carrying one or more blades (1), mounted so that pitch variation is effected automatically by centrifugal/aerodynamic forces. The mounting includes a pivot (4) lying in the plane perpendicular to the axis of rotation (3) but inclined at an angle (gamma), pref. acute, to the line (5, b1) of the blade axis with the blade upright. Pitch change is therefore accompanied by angular movement (beta) away from the upright; limiting stops are embodied in the hub.
