Claim Text:
1. A pitch control assembly for a vertical axis wind turbine that provides greater efficiency to the vertical axis wind turbine, the pitch control assembly comprising, a pitch control assembly housing mechanically coupled to a first stop bar, a second stop bar and a cushion mass; the pitch control assembly housing is mechanically coupled to a pitch control assembly bottom plate where the pitch control assembly bottom plate is mechanically coupled to a dampening spring; the dampening spring is mechanically coupled to a blade control plate, where the blade control plate is mechanically coupled to a first blade control pusher bar, a second blade control pusher bar and a blade control plate stem; a heavier mass and a lighter mass rest upon the blade control plate; the blade control plate stem is mechanically coupled to a vertical axis which is used in the vertical axis wind turbine; in this manner, the heavier mass and the lighter mass allow an air foil blade to rotate in either direction which converts wind energy into rotational energy that accelerates the air foil blade and increases rotation of a rotor arm affixed to the pitch control assembly housing and the air foil blade until linear velocity of the air foil blade exceeds a given velocity where the heavier mass pushes against the first blade control pusher bar and the lighter mass pushes against the second blade control pusher bar locking the air foil blade in a position tangent to the rotor arm.
