Abstract
This invention relates to a method and apparatus for reproducing operating conditions in induced flow devices, such as carburetors and the like, and more particularly to a system for reproducing such operating conditions which may be used in testing systems designed to test induced flow devices. In operation in such a test system, the apparatus of the present invention would cause a given air flow to flow through an induced flow device such as a carburetor, and then would cause the throttle plate of the carburetor to be rotated until the desired manifold vacuum in the carburetor is obtained, at which time the test of the carburetor could take place. By providing a throttle drive controller to move the carburetor throttle at a speed which is proportional to the difference in the manifold vacuum actually present in the carburetor, and the desired manifold vacuum, a very rapid movement of the throttle plate between test points can be had, but at the same time a slow approach to the actual test point, to prevent overshoot, is accomplished. A continuous monitoring of the difference between the manifold vacuum in the carburetor, and the desired manifold vacuum, is accomplished by a conti…
