Patent number: 7980485Abstract: A fuel injector for an internal combustion engine is disclosed. The fuel injector includes a housing, a valve seat, a metering orifice disc, and a needle. The housing has an inlet, an outlet, and a longitudinal axis extending therethrough. The valve seat is disposed proximate the outlet and includes a passage having a sealing surface and an orifice. The metering orifice disc is located at the outlet and has a plurality of metering openings extending therethrough. The needle is reciprocally located within the housing along the longitudinal axis between a first position wherein the needle is displaced from the valve seat, allowing fuel flow past the needle, and a second position wherein the needle is biased against the valve seat, precluding fuel flow past the needle. A generally annular channel is formed between the valve seat and the metering orifice disc. The channel tapers outwardly from a large height to a smaller height toward the orifice openings.Type: GrantFiled: March 24, 2004Date of Patent: July 19, 2011Assignee: Continental Automotive Systems US, Inc.Inventor: William A.
