摘要

A nozzle (10) for a fuel injector for internal combustion engines, having a body (12) of corrosion-resistant material with a longitudinal bore (14) closed at its bottom end and having a cylindrical guide surface (16), wherein a plurality of nozzle bores (18) is formed in a lateral wall of the body, and wherein said cylindrical guide surface (16) is formed on either:
a wear resistant layer (20) formed on an inner surface (22) of the body (12) of corrosion resistant material, or
a tubular sleeve (24) of wear resistant material inserted into said longitudinal bore (14).
