Abstract
An orifice plate 21 is attached at the tip of an injector 1 to cover a fuel passage hole 18. The orifice plate 21 is provided with a plurality of orifices 24 for allowing fuel having passed through the fuel passage hole 18 to be injected. The orifice plate 21 includes a plate body 23 constructed in layers, and each orifice 24 is constructed of a plurality of holes 27a-27d each formed in each layer of the plate body 23 so that each hole is perpendicular to a surface of the plate body 23, the holes being disposed in communication with each other and with displacements from each other along a line obliquely intersecting the plate body.
Claims8
An orifice plate which is mounted at a tip of an injector to cover a fuel passage hole formed at the tip, the orifice plate including:
- a plate body constructed in layers;
- and
- an orifice for allowing fuel having gassed through the fuel passage hole to be injected;
- wherein the orifice is constructed of a plurality of holes each formed in each layer of the plate body so that each hole is perpendicular to a surface of the plate body, the holes being disposed in communication with each other and with displacements from each other along a line obliquely intersecting the plate body, and
- wherein the plate body includes a plurality of disks which are superposed on top of each other and a joint part which joins the adjacent disks in an unfolded state and is folded to construct the layered plate body.
