    摘要： An actuator rail assembly for conveying an actuating fluid under pressure to at least one fuel injector includes an elongate fluid passageway (18) being defined in a rail (12). A fluid inlet port (31) is in fluid communication with the fluid passageway (18), 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 (16) having at least one throttling orifice (14), the orifice effecting fluid communication between the fluid cavity (16) and the fluid passageway (18). An acoustic wave attenuator and a method of attenuation are also included.

    摘要： A mechanical oscillator for attenuating pressure waves formed in a rail having a volume of fluid therein includes a rigid enclosed fluid cavity having a selected volume, the volume communicating with the rail actuating fluid though an orifice having a select volume for containing actuating fluid, the orifice having an aperture in fluid communication with the actuating fluid selected such that when an pressure wave impinges on the aperture of the orifice, the motion of the actuating fluid in the volume of the orifice is set to vibrating, the vibrating acting to excite the actuating fluid within the enclosed volume, a resulting amplified motion of the actuating fluid in the orifice, due to phase cancellation between the actuating fluid in the volume of the orifice and the actuating fluid volume in the enclosed cavity, causing energy absorption of the pressure wave due to frictional drag in and around the orifice. An pressure wave attenuator and a method of attenuation are also included.
