Abstract
A spill type swirl injector includes a nozzle body, an injection port, a pressurized fluid induction passage, a valve assembly, a swirl chamber, two tangential pressurized fluid supply passages and a spill assembly including two spill openings provided on an outer cylindrical wall of a movable member of the valve assembly and opened to inner side of the swirl chamber. An axial hole provided in the movable member of the valve assembly and in the nozzle body and discharge passage assembly is connected to a pressurized fluid supply source, thereby spilling a predetermined quantity of the pressurized fluid from the inner side of the swirl chamber through the spill opening, axial hole and spill passage assembly. The spill type swirl injector immediately injects the fluid in the form of a liquid film flow having a sufficiently high swirling velocity, after the valve is opened, so that the sprayed liquid droplets are remarkably fine and uniform and the atomizing characteristics and response of the atomization to the injection pressure are improved in comparison with prior spill type swirl injectors.
