ABSTRACT:
A fuel control assembly includes a valve closure member, a fuel inlet restricting member, and a fuel outlet cleaning member which are connected together for simultaneous movement. The valve closure member is movable within a valve body by a crank pin on a rotatable valve control shaft, and the valve closure member is movable in both directions beyond a sealing position in which the valve closure member cooperates with the valve body to shut off fuel flow through the valve body. Movement of the valve closure member in one direction beyond the sealing position maintains the fuel flow path closed and moves the fuel outlet cleaning member into the fuel outlet orifice to clean the orifice. Movement of the valve closure member in the other direction beyond the sealing position maintains the fuel flow path open and first moves the fuel inlet restricting member into the fuel inlet to restrict fuel flow through the inlet and thereafter moves the fuel inlet restricting member out of the fuel inlet to permit fuel to flow through the inlet unrestricted.
