Testing bench especially for mechanical as well as electronic pumps and injectors, in supply systems for internal combustion engines.

摘要

This bench is especially convenient for the testing of mechanical as well as electronic pumps and injectors of supply systems for internal combustion engines of vehicles.It includes a hydraulic circuit composed of at least one tube for withdrawal from the liquid reservoir, from which, at least one installation tube for the supply pump under test is derived.The withdrawing tube is divided into two branches, of which the first has an attachment end for a single injector, and an end for the checks of the above mentioned pump under test.The second branch has a circuit purging and discharge end, and a series of attachment ends for the corresponding injectors to be contemporaneously tested.All circuit ends discharge the liquid into a receptacle connected to the reservoir.The hydraulic circuit has flow parameter control regulatory mechanisms, and valve mechanisms for the selection of the flow courses.The electronic circuit, with its related control panel, is connected to these selector valve mechanisms, and oversees the operation of the system tubing as well as the various elements under test.Everything is placed inside a containing and support structure.
