US Classification:
2395339
Abstract:
A fuel injector has a swirl plate about a valve assembly, including a valve seat with an orifice and a valve pin. When the valve is opened, the fuel is swirled by the swirl plate for passage through the orifice. The orifice has a portion which is angled relative to the axis of the injector to provide a conical swirling spray pattern having a conical spray axis angularly related to the axis of the injector. In another form, the orifice is on-axis with the injector and receives a bent tube having an upstream on-axis portion and a downstream angled portion to direct the swirling conical spray at an included obtuse angle relative to the axis of the injector.

Abstract:
A fuel injector with a valve body having an inlet, an outlet, and an axially extending fuel passageway from the inlet to the outlet. An armature proximate the inlet of the valve body. A needle valve operatively connected to the armature. A valve seat proximate the outlet of said valve body. A fault tolerant structural connection between the valve seat and valve body that also provides a hermetic seal between the valve seat and valve body.

Abstract:
Projection welding is used to join a needle guide member and a valve seat member together preparatory to their assembly into the nozzle of a fuel injector. Various embodiments are disclosed, including various ways for creating the projections. In the preferred embodiment the projections on the end face of the guide member are made my forming a small holes in the frustoconical surface of the guide plate. As the tool is used to form the small holes in the guide plate, the material of the guide plate is displaced creating small projections from the frustoconial guide surface.
