FLUID PASSAGE ORIFICE RING AND METHOD

摘要

An orifice ring (316) arranged to be press-fit into a passage (308) includes an orifice face (318) having an opening (320) formed therein, a retention porti on (326) having an edge (402) disposed opposite the orifice face (318), and a curved portion (404) disposed between the orifice face (318) and the retention portion(326) . The retention portion (326) is oriented such that the edge (402) lies further outward than the orifice face (318). The retention portion (326) is arranged to elastical ly deflect inward toward the orifice face (318) when the orifice ring (316) is disposed in a passage (308).
