  • Patent number: 7140560
    Abstract: A deflector at the downstream end of a fuel tube deflects incoming fuel into an annular fuel channel in a fuel swirler of an injector. The deflector prevents direct impact of the cooler fuel on the exposed walls of the swirler body. The deflector can be formed by a tab or other integral portion of the heatshield, or as a separate piece fixed to the heatshield or swirler body. The deflector minimizes disruption of flow through any flow slots that are covered by the deflector, and may have i) a relatively small circumferential extent, such that the deflector covers only a few flow slots, ii) flow openings or slots that allow a portion of the fuel to flow inwardly of the deflector into the otherwise covered flow slot(s), or iii) a space or gap between the side(s) of the deflector and the inner walls of the annular channel.

  • Patent number: 6345776
    Abstract: A two-component dispensing gun has two longitudinally-extending dispensing passages receiving metering rods and in fluid communication with two feed passages adjacent to an especially configured metering rod tip and valve seats formed at the exit end of each dispensing passage. Valve seats of the dispensing passage extend as protrusions from the gun nose and are sealingly received within cup shaped recesses formed in a detachable, throwaway nozzle having a static mixing chamber. The nozzle has a truncated cone configuration which, in combination with the geometric configuration of the dispensing and feed passages alleviates turbulent flow of the liquid components until reaching the static mixer within the nozzle. A cammed surface on each metering rod in combination with a yoke crossbar formed as part of the gun's trigger provides increased motion of the trigger for fine or slow metering applications of the gun.
