Abstract
A method and apparatus is provided for regulating the flow of rates of particulate matter. The invention includes a flow gate with a generally cylindrical body having a flow path defined there through. A stator member is provided in fixed position relative to the cylindrical body. The stator member has a plurality of alternating tapered vein portions and inlet portions. A rotor member is interfaced with the stator member. The rotor member has a plurality of alternating stock portions and outlet port portions. The rotary coupling is utilized to couple the rotor member and the stator member. A position actuator is provided for receiving at least one control input and producing a corresponding displacement of the rotor member. A mechanical coupling is provided between the position actuator and the rotor member. The flow gate is utilized to obtain a particular flow rate within a range of available flow rates by determining the relative positions of the inlet ports of the stator member and the outlet ports of the rotor member.
