摘要： 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.

摘要： A throttle device comprises a device housing with an inlet and an outlet and a throttle element arranged in a connecting duct connecting the inlet and the outlet, said throttle element comprising at least two throttle components to be adjusted relative to one another and by the relative position of which an opening surface of the throttle element is determined, at least the first throttle component being actively connected with a drive means for an adjustment relative to the second throttle component. In order to guarantee with a simplified construction a safe operation of the throttle device without the risk of a choking of the corresponding throttle element and to simultaneously realize a simple possibility of movement for the throttle components, the throttle components are throttling discs to be rotated relative one to another at least one of which being movably connected with a rotary adjustment device of the drive means, the throttling dics each comprising at least one throttle opening the overlap of which determines the opening surface depending on the relative position of the throttling discs.
