  • Apparatus for testing high pressure injector elements
    Patent number: 5412981
    Abstract: An apparatus for testing and evaluating the spray pattern of high pressure fuel injector elements for use in supplying fuel to combustion engines. Prior art fuel injector elements were normally tested by use of low pressure apparatuses which did not provide a purge to prevent mist from obscuring the injector element or to prevent frosting of the view windows; could utilize only one fluid during each test; and had their viewing ports positioned one hundred eighty (180.degree.) apart, thus preventing optimum use of laser diagnostics.
