Co-axial dual fluids metering system and methods
First Claim
1. A metering system for a fluid atomizer, comprising:
- a housing having a first fluid inlet, a second fluid inlet, and an outlet;
a mixing chamber;
a first fluid metering device comprising;
a rear end arranged away from the housing outlet;
a front end arranged toward the housing outlet;
a plurality of first fluid channels spaced apart circumferentially in the housing, the plurality of first fluid channels being angled in at least one of a radially inward direction and a tangential direction to create a swirl of first fluid flow in the mixing chamber;
a first fluid flow controller positioned in the housing and movable axially in a flow channel provided between the first fluid inlet and the plurality of first fluid channels to control flow of first fluid from the first fluid inlet to the plurality of first fluid channels, the first fluid flow controller having a rearward most surface, a forward most surface, and a pass through bore;
a second fluid metering device configured to control second fluid flow from the second fluid inlet to the mixing chamber, the second fluid metering device being arranged radially inward from and coaxially with the first fluid metering device, the second fluid metering device extending through the pass through bore of the first fluid flow controller from a location rearward of the rearward most surface to a location forward of the forward most surface of the first fluid flow controller to deliver the second fluid from a location rearward of the first fluid flow controller to the mixing chamber.

Abstract
A metering system for a fuel atomizer includes a housing having a fuel inlet and an oxidizer inlet arranged coaxially, and an oxidizer metering device having a plurality of oxidizer channels, an oxidizer flow controller, and a fuel metering device. The oxidizer channels are spaced apart circumferentially in the housing and are arranged angled in at least one of a radially inward direction and a tangential direction to create a swirl of oxidizer flow in a mixing chamber of the fuel atomizer. The oxidizer flow controller is configured to control flow of oxidizer from the oxidizer inlet to the plurality of oxidizer channels. The fuel metering device is configured to control fuel flow from the fuel inlet to the mixing chamber.

11. A method of metering a first fluid and a second fluid for a fluid atomizer, comprising:
-
providing a housing, a mixing chamber, a nozzle, a first fluid metering device, a second fluid metering device, and a plurality of first fluid channels leading to the mixing chamber, the housing having a first fluid inlet, the first fluid metering device being arranged co-axially with, radially outward from, and coextensive with the second fluid metering device from a front end to a rear end of the first fluid metering device, the second fluid metering device having an internal fluid channel; moving the first fluid metering device axially within a flow channel provided between the first fluid inlet and the plurality of first fluid channels to control first fluid flow through the plurality of first fluid channels to the mixing chamber to create a flow of first fluid into the mixing chamber; moving the second fluid metering device independent of movement of the first fluid metering member to control second fluid flow to the mixing chamber to create a mixture of first fluid and second fluid in the mixing chamber, the flow of second fluid being delivered through the internal fluid channel from a location rearward of the first fluid metering member to the mixing chamber; and delivering the mixture out of the nozzle. - View Dependent Claims (12, 13, 14, 15, 16)

17. A fluid mixing device, comprising:
-
a housing; a mixing chamber; a first fluid inlet; a first fluid metering device positioned in the housing and configured to deliver a first fluid from the first fluid inlet to the mixing chamber; a second fluid metering device positioned in the housing and arranged coaxially with the first fluid metering device, the second fluid metering device extending through the first fluid metering device; a first fluid chamber arranged radially outward from the second fluid metering device; a plurality of circumferentially spaced apart channels extending from the first fluid chamber to the mixing chamber; and at least two supply ducts extending through a sidewall of the housing and configured to provide flow of the first fluid to the first fluid chamber, the at least two supply ducts being positioned forward of the second fluid inlet; wherein the first fluid metering device is movable axially within the first fluid chamber to control flow of the first fluid through the plurality of channels to the mixing chamber. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
