Abstract
A system including a variable orifice component including a main body, a main fuel path extending through the main body, and a control body positioned in the main body. The control body is movable between a first position wherein a first fuel path thereof is in fluid communication with the main fuel path to enable fuel to flow therethrough, and a second position wherein a second fuel path thereof is in fluid communication with the main fuel path to enable fuel to flow therethrough. The system further includes a vent body coupled to the main body. The vent body is movable between a first position wherein the main fuel path is in fluid communication with a vent orifice of the vent body to provide fluid communication between the main fuel path and a surrounding environment, and a second position wherein the main fuel path is not in fluid communication with the vent orifice.
