Jet pump spool valve

A system to control flow of a fluid therethrough, the system comprising:

• a storage tank;
• a header tank fluidly coupled to the storage tank;
• and
• an integrated jet valve fluidly coupled between the storage tank and the header tank, the integrated jet valve fluidly coupled to a fuel pump of the header tank via a bleed line, the integrated jet valve including:
• a valve body;
• a juncture operatively coupled to the valve body, the juncture having a first fluid connection fluidly coupled to the header tank and a second connection fluidly coupled to the storage tank;
• a spool movably disposed within the valve body, the spool having an aperture extending longitudinally therethrough;
• a spring operatively coupled between the spool and the valve body;
• and
• a jet pump disposed within the aperture, wherein:
• operation of the fuel pump pressurizes the bleed line and moves the spool to a first position to:
• (i) close a first fluid path between the header tank and the storage tank and (ii) provide a second fluid path between the header tank and the storage tank, the second fluid path through the aperture, and
• depressurization of the bleed line enables the spring to move the spool to a second position to close the second fluid path and open the first fluid path.

A method of producing a system for controlling flow of a fluid therethrough, the method comprising:

• fluidly coupling a storage tank to a header tank;
• fluidly coupling a jet valve between the storage tank and the header tank;
• and
• fluidly coupling the jet valve to a fuel pump of the header tank via a bleed line, the jet valve including:
• a valve body;
• a juncture operatively coupled to the valve body, the juncture having a first fluid connection fluidly coupled to the header tank and a second connection fluidly coupled to the storage tank;
• a spool movably disposed within the valve body, the spool having an aperture extending longitudinally therethrough;
