Abstract
A valve system includes a spin chamber having an outlet drain configured to allow flow out of the spin chamber. A main spin surface of the spin chamber is defined around the outlet drain. A directional jet system is in fluid communication with the spin chamber. The directional jet system includes a member that is configured to move between a first position for directing a tangential flow around the drain, and a second position for directing a radial flow toward the drain.
Claims19
A valve system comprising:
- a spin chamber having an outlet drain configured to allow flow out of the spin chamber, wherein a main spin surface of the spin chamber is defined around the outlet drain;
- and
- a directional jet system for a fuel in fluid communication with the spin chamber, wherein the directional jet system includes a jet member that is configured to move between a first position for directing a tangential flow around the drain, and a second position for directing a radial flow toward the drain;
- wherein the member is disposed at a periphery of the spin chamber and wherein a portion of the member directing the flow extends closer to the outlet drain with the member in the second position than with the member in the first position.

A valve system comprising:
- a spin chamber having an outlet drain configured to allow flow out of the spin chamber, wherein a main spin surface of the spin chamber is defined around the outlet drain;
- and
- a directional jet system for a fuel in fluid communication with the spin chamber, wherein the directional jet system includes a jet member that is configured to move between a first position for directing a tangential flow around the drain, and a second position for directing a radial flow toward the drain;
- wherein the jet member includes a jet tube, wherein a jet orifice is defined at an outlet end of the jet tube, wherein the directional jet system is configured to rotate the jet tube to direct the jet orifice more toward a periphery of the spin chamber in the first position relative to the second position, and wherein the directional jet system is configured to rotate the jet tube to direct the jet orifice more toward the drain outlet in the second position relative to the first position.

A valve system comprising:
- a spin chamber having an outlet drain configured to allow flow out of the spin chamber, wherein a main spin surface of the spin chamber is defined around the outlet drain, wherein the spin chamber is circular;
- and
- a directional jet system for a fuel in fluid communication with the spin chamber, wherein the directional jet system includes a member that is configured to move between a first position for directing a tangential flow around the drain, and a second position for directing a radial flow toward the drain;
- wherein the member is at least partially within and at a periphery of the spin chamber.
