Abstract
An injector for delivering a working fluid into a working environment is disclosed. According to one embodiment of the present invention, the injector includes a pre-metering chamber and a swirl chamber. A high velocity partially atomized flow is produced in the pre-metering chamber through a first exit nozzle after impinging on an atomization element, and then a swirling flow is created in the swirl chamber with the atomization element. When the swirling flow is released through a second exit nozzle, atomization can be achieved at low injector pressure with centrifugal force and shearing of the working fluid. In another embodiment, the injector includes a swirl chamber and an atomization element with a bore, through which a control valve is positioned. The control valve forces a working fluid flow through the atomization element when the injector is energized to create a swirling flow. No flow-back is required for the injectors.
