Abstract
A fuel injector nozzle assembly is disclosed. The assembly may include a nozzle casing, a first tip member, and a second tip member. The first tip member may extend longitudinally within the nozzle casing and may define first and second shoulders on the first tip member. The second tip member may extend longitudinally within the nozzle casing and may be arranged in predetermined rotational alignment with the first tip member. The second tip member may define a third shoulder on the second tip member configured to interact with the first shoulder to oppose rotation of the first tip member relative the second tip member in a first direction about a longitudinal axis of the first tip member. The second tip member may further define a fourth shoulder on the second tip member configured to interact with the second shoulder to oppose rotation of the first tip member relative the second tip member in a second direction about a longitudinal axis of the first tip member.
