Abstract:
1. An injector, comprising: a metering set including a plate of etchable material, the plate having a first side and a second side, the first side having a bowl-shaped swirl chamber shaped by etching such that a first fluid to be dispensed from the injector can move therein in a vortex motion toward the center of the swirl chamber; an orifice in fluid communication with the center of the swirl chamber and extending substantially co-axial therewith to the second side such that first fluid to be dispensed from the injector can move from the swirl chamber to the orifice and then exit the orifice through the second side; at least one first feed slot in fluid communication with the swirl chamber and extending in non-radial relation thereto for supplying the first fluid to be dispensed through the injector; and a swirler assembly including a plate of etchable material, the plate of the swirler assembly arranged alongside the second side of the plate of the metering set, a swirler passage shaped by etching through the plate of the swirler assembly, the swirler passage located in relation to the orifice of the plate of the metering set such that the first fluid directed through the orifice passes through the swirler passage and a second, swirling fluid can be imparted to the first fluid to cause the first fluid to have a swirling component of motion; and at least one second feed slot in fluid communication with the swirler passage for supplying the second fluid to be swirled in the swirler passage.
