Abstract
A fuel injector assembly includes a housing having a plurality of injector bores, a plurality of fuel feed bore, each intersecting a corresponding one of the injector bores, and a common return passage which communicates all the fuel feed bores with a fuel reservoir. A fuel injector is mounted in each of the injector bores. Each injector has a return fuel port which communicates return fuel to an exterior of the injector. A fuel feed member is mounted in each of the fuel feed bores. Each fuel feed member has a fuel feed passage which communicates pressurized fuel to a corresponding one of the injectors. An outer surface of each fuel feed member and a wall of each fuel feed bore forms a return chamber which is communicated with a corresponding return fuel port and which is communicated with the common return passage.
