Abstract
A jet valve includes a valve body, a juncture operatively coupled to the valve body. The juncture having a first fluid connection fluidly coupled to a header tank and a second connection fluidly coupled to a storage tank. A spool is movably disposed within the valve body. A jet pump is fluidly coupled to a fuel pump of the header tank via a bleed line. 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. 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 jet valve to control flow of a fluid therethrough, the jet valve comprising:
- a valve body;
- a juncture operatively coupled to the valve body, the juncture having a first fluid connection fluidly coupled to a header tank and a second connection fluidly coupled to a 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 fluidly coupled to a fuel pump of the header tank via a bleed line, the 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 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;
- 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
