Abstract
An engine head assembly includes a plurality of fuel injectors each positioned within a fuel injector bore in the engine head, and each being fluidly coupled with a fluid conduit. Each fuel injector includes a valve assembly positioned within a fuel injector case that includes an elongate body having an opening. A filter sleeve having a particle-blocking perforation array structured to block particles is press fit on the fuel injector case to form a fluid flow path from the fluid conduit into the fuel injector case.
