Abstract: A fuel distributor for supplying fuel to injection valves for internal combustion engines includes a hollow manifold having a plurality of branch bores disposed radially therethrough. A plurality of branch lines are operably connected with a manifold at the branch bores by adapters. The adapters have either a one-piece deep-drawn construction or a one-piece extruded construction, and include a mounting flange that conforms to the outer contour of the manifold and joins the adapter to the exterior of the manifold, and a neck portion that closely receives and securely mounts therein the end portions of the branch lines.

Abstract: A flow splitter that divides a two-phase (gas-liquid) inlet stream or a one-phase (liquid-liquid) inlet stream into equal and substantially balanced parts for distribution to an equal number of outlets horizontally oriented and connected to the flow splitter. Because of the design of the flow splitter, no control instrumentation or retention time is required during a split. Openings in each face of the flow splitter help to equalize pressure in the split and allow liquid to fill an end chamber that supports impact forces on a wedge-shaped spreader oriented with its leading edge toward an inlet stream.

Abstract: In a branch tee fitting (1) fabricated by press forming, engaging pawls (14) are provided which engage flat portions (13) superposed to each other at angles in the region between the tubular body portion (11) and the tubular branch portion (12), in order to enhance the brazing strength thereof and the brazing workability thereof by allowing separate brazing of pipes (P) to a tubular body portion (11) and a tubular branch portion (12).

Abstract: Thin walled compartmented tubular structure and its manufacturing process. The elbow or T-shaped structure, includes an external wall (14)and continuous internal walls (22) made in one piece. This therefore materializes, between the inlet (10) and each outlet (12) of the structure, at least one continuous passage to direct a fluid circulating inside it. The structure according to the invention is manufactured by diffusion welding and superplastic forming, from titanium alloy sheets. One application is for aircraft de-icing circuits.

Abstract: A fuel system has a fuel injector directly mounted with a fuel rail. The fuel rail has a body with interior and exterior surfaces. The interior surface defines a volume. The exterior surface surrounds the interior surface. An aperture extends between the interior and exterior surfaces in fluid communication with the volume. The fuel injector has an inlet tube with an inside surface that defines a flow path through a portion of the fuel injector, and an outside surface that surrounds the inside surface. The fuel injector is disposed so that the flow path is in fluid communication with the volume. A rigid connection is disposed between at least one of the interior and exterior surfaces of the fuel rail and the outside surface of the inlet tube, the rigid connection securing and hermetically sealing the fuel rail with the fuel injector.

Abstract: A fuel system has a fuel injector directly mounted with a fuel rail. The fuel rail includes a first portion and a second portion that form a body. The body has an interior surface defining a volume, an exterior surface surrounding the interior surface, and at least one aperture disposed between the interior and exterior surfaces in fluid communication with the volume. The at least one fuel injector has an inlet tube with an inside surface defining a flow path through a portion of the fuel injector and an outside surface surrounding the inside surface. The fuel injector is disposed such that the flow path is in fluid communication with the volume. A rigid connection is disposed between the interior surface of the fuel rail and at least one of the outside surface and the inside surface of the inlet tube. The rigid connection secures and hermetically seals the fuel rail with the at least one fuel injector.
