Abstract
Equipment for monitoring the performance of an engine fuel injector valve includes a source of pressurized fluid and an injector valve head connected to an injector valve and the source so that pressurized fluid is delivered to the valve. A regulator compensates for changes in pressure of the fluid and enables the change to be effected and maintained. A flow monitor is in the fluid path between the source and the head to monitor the flow of fluid. The source of pressurized fluid maintains a level of pressure in excess of a desired operating pressure. A fluid flow control coupled to a pressure sensor, near the test head indicates the pressure therein so that the flow control effects flow through the fluid path to maintain the pressure at the head.
