摘要:
A flow limiter for a fuel system is provided. The flow limiter includes a self-contained portion that enables testing of the flow limiter prior to assembly into a fuel system. A housing of the flow limiter is arranged to provide reduced or no pressure differential across a wall of the housing, permitting the housing to be reduced in size and thickness and providing improved consistency of operation.
摘要:
A fuel injector that includes an injector control valve assembly. The injector control valve assembly includes a contact spring positioned between a fuel injector upper body and the injector control valve assembly to isolate a stator housing from clamping forces that occur during fuel injector assembly and clamping in an internal combustion engine. The injector control valve assembly further includes a cartridge configuration that permits preassembly of the injector control valve assembly prior to mounting in the fuel injector.
摘要:
A fuel injector including an injection control device valve spring preload adjustment device is disclosed. The fuel injector includes a transverse access passage extending at an acute angle to a longitudinal axis of the fuel injector. The preload adjustment device includes at least one transverse slot that creates a cantilevered thread portion. The cantilevered thread portion is deformed at a deformation angle to a plane perpendicular to the longitudinal axis to form a locking feature.
摘要:
A fuel injector control valve is provided that includes a drain circuit for directing the flow of fuel away from temperature sensitive components of a fuel injector in which the fuel injector control valve is positioned. The drain circuit includes at least one portion that directs drain fuel axially inward or toward a fuel injector orifice, and away from an actuator of the fuel injector.
