As shown in Fig. 1, the locator 32 is a flange and the resilient means a rubber 0-ring, which when the atomizer is a fuel injector in an I.C. engine seals the connection between the cover 10 and an engine manifold 18. In Fig. 4, the locator is a groove 54 in which a resilient rubber 0-ring seats. In an alternative (Fig. 3, not shown) the 0-ring does not seal between the cover and the engine manifold. The atomizer may be used as a fuel injector for central heating burners or as a chemical or paint sprayer. |
