Impelling mechanism

An impelling mechanism comprising:

• a housing defined by an upper casing and a lower casing, at least one swept volume chamber formed in said upper casing, at least one fluid input port in communication with said swept volume chamber, at least one fluid output port in communication with said swept volume chamber;
• a shaft oriented substantially perpendicular to the top wall of said upper casing with said shaft passing therethrough and being journaled to rotate freely with respect to said upper casing;
• a rotor member fixedly mounted on said shaft and being located in said housing, a portion of the top surface of said rotor member forming the bottom wall of said swept volume chamber, a plurality of blade members each of which is mounted on its own crankshaft, said blade members being positioned within said swept volume chamber and their crankshaft being oriented substantially perpendicular to said rotor member and being journaled therein;
• and
• means for controlling the blade attitude of each of said blade members so that they all maintain the same attitude as the rotor member travels through its 360 degree revolution comprising said crankshafts each having at least one crankshaft throw that is journaled in a blade attitude control member that is journaled about a disc member within which said shaft is journaled, said disc having a fixed relationship with said lower casing.
