Abstract (en)

[origin: WO2006056552A2] The invention relates to a device (1) for damping liquid pressure waves in conduits (2) and containers that conduct and/or store liquids, in particular in conduits and containers of injection systems in motor vehicles. According to the invention, to convert vibrational energy into thermal energy, at least one reflection surface (10) for reflecting at least some of the liquid pressure waves is provided in the container or in the conduit (2) in a region (12; 28) that is separate from the remainder of the container or the conduit (2).
