FUEL INJECTOR WITH FLOATING SLEEVE CONTROL CHAMBER

摘要

A fuel injector including a floating sleeve control chamber (142) is provided which effectively minimizes friction and wear of a nozzle valve element by avoiding the need to align two bore guiding surfaces for the element. The floating sleeve control chamber includes a floating sleeve (138) positioned on a control piston (136) formed integrally with a nozzle element and positioned in a cavity.
