  • Fuel injector nozzle assembly having anti-cavitation vent and method
    Patent number: 10895231
    Abstract: A nozzle assembly for a fuel injector includes an injector housing having a casing and a stack within the casing, an outlet check movable within a nozzle cavity in the injector housing, and having a stop positioned within a stop cavity. A clearance is formed between the outlet check and the injector housing and fluidly connects a spring cavity to a stop cavity, and an anti-cavitation vent is formed in the stack and fluidly connects the spring cavity to a low pressure space. The anti-cavitation vent limits pressure changes in the spring cavity during fuel injection such that production of cavitation bubbles in the spring cavity is limited.
