ABSTRACT:
A single-point fuel injection system including an electromagnetically-operable ball valve injector. The injector comprises a hollow body which is surrounded by an annular gallery through which fuel is circulated under pressure continuously. Inlet ports are formed in the body whereby fuel from the gallery enters a chamber within the body in a direction transverse to the axis of the injector. The chamber communicates with the nozzle orifice via an aperture within which the ball valve is located. The difference between the diameter of the aperture and the diameter of the ball is sufficiently small to restrict fuel flow from the chamber to the nozzle orifice so that the valve is urged to seat and close the nozzle orifice by the differential fluid pressure loading on it.
