Abstract

The optical system allows the detection of the opening and then the control and diagnostics of injectors of any type, with any type of petrol and supply, as well as other mechanical moving parts drowned in a fluid. This system includes: - a measuring environment with an almost watertight chamber, - a fixed body, such as the body (8) of an injector, having at least two coaxial holes (3) of any geometry, - movable body, such as a control piston (7), having at least one through hole (4) of any geometry, - at least one diode (1) for the emission of an infrared or other light frequency beam placed in one of said coaxial holes (3) drilled on the fixed body, - at least one photoreceiver transistor (2) for receiving said beam, positioned frontally to said diode, and placed in the second of said coaxial holes (3) formed on the fixed body, - an electronic circuit for the transmission and reception of the light signal. The diode (1) emits an infrared or other light frequency beam which, passing through the coaxial holes (3) on the fixed body and the through hole (4) on the movable body, reaches the photoreceiver (2) that produces an indicative voltage derived from the intensity of the received light signal which is due to the displacement of the movable body with respect to the fixed body, said voltage being proportional to the percentage of juxtaposition between said through holes of the fixed body and said through hole of the movable body.
