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.
