摘要: A hybrid atomizing fuel nozzle includes a stem with primary and secondary fuel circuits. A nozzle assembly fixed at the downstream end of the stem includes primary and secondary nozzle portions. A shroud and swirler assembly surrounds the nozzle assembly, and includes an annular body with a prefilmer surface. A radial inflow swirler in the annular body directs a first swirling air flow radially inward toward the secondary nozzle portion. An outer air swirler disposed in surrounding relation to the annular body provides a converging second swirling air flow downstream of the prefilmer surface. Discrete fuel passages direct fuel streams outward and downstream toward and against the prefilmer surface. The fuel passes through the first air flow and is evenly distributed across the prefilmer surface in a thin continuous sheet. The first and second air flows then cause the sheet to form a conical spray of atomized fuel.

摘要: A flow dividing valve wherein an outer sleeve (26) is maintained in a valve body (10) and has a primary flow valve seat (32). An inner valve sleeve (50) that is slidably maintained in outer sleeve (26) has an end face (51) that cooperates with the valve seat (32) to control primary flow. A valve spool (74) that is slidably maintained in inner valve sleeve (50) cooperates with a secondary flow valve seat (70) of inner valve sleeve (50) to control secondary flow.
