Abstract
Abstract A nozzle integrally mounted in a manifold tube which distends in response to internal pressure to vary the flow rate. The nozzle comprises a pintle having a threaded mounting section and a conical seat engageable with the manifold orifice. The mounting section is threaded directly into the manifold tube and the pintle is adjustable by a screwdriver slot to achieve the proper flow setting. A brazing ring is carried by each mounting portion, and all pintles on the manifold are simultaneously secured in position by placing the manifold in a brazing furnace.
