    摘要: The device for damping noise in a hydraulic circuit, particularly in a fuel line (18), comprises an inlet chamber (3) that is connected to a first channel (11). The first channel is connected to an inter-chamber (9) whereby the inter-chamber is located beside the inlet chamber. The inlet-chamber is connected downstream via a second channel (12) to an outlet chamber (4). The outlet chamber is arranged beside the inter-chamber. The diameter of the inlet and outlet chamber is larger than the diameter of the first and the second channel. This arrangement reduces the noise of a pressure wave that arrives at the inlet chamber, whereby the pressure wave is guided by the first channel to the inter-chamber and by the second channel from the inter-chamber to the outlet chamber.
