ABSTRACT:
An actuator rail assembly for conveying an actuating fluid under pressure to at least one fuel injector, include an elongate fluid passageway being defined in a rail. A fluid inlet port is in fluid communication with the fluid passageway, the inlet port being fluidly couplable to a source of actuating fluid under pressure. A respective fluid outlet port is associated with each respective fuel injector and being fluidly couplable thereto for conveying actuating fluid to the respective fuel injector; and at least one fluid cavity having at least one throttling orifice, the orifice effecting fluid communication between the fluid cavity and the fluid passageway. An acoustic wave attenuator and a method of attenuation are also included.
