Injection system and method for injecting a cylindrical array of liquid jets

Abstract:

An injection system includes a reservoir for containing liquid, and a gating plate having a circular array of gating plate apertures. The injection system additionally includes a faceplate positioned adjacent to the gating plate and having a circular array of faceplate orifices. The injection system also has a motor to rotate the gating plate, and a controller to control the motor for rotating the gating plate into an aligned clocking orientation in which the gating plate apertures and the faceplate orifices are aligned to initiate the formation of a cylindrical array of liquid jets, and rotate the gating plate into a non-aligned clocking orientation terminate formation of the liquid jets after a predetermined discrete quantity of the liquid is injected.
