Device for deadening compressive pulsations in a fluid system like a fuel system for an ICE has a casing, a hollow area with an intermittent working area linked to a flow path for a liquid system and intermittent preload devices for gas.

摘要

A casing has a hollow area (68) with an intermittent working area (84) linked to a flow path (22) for a fluid system (10) like a fuel system in an internal combustion engine (ICE) (28). Intermittently available preload devices (80) have a gas volume and preload a contact surface (82) in the intermittent working area so that a dynamic pressure change in the flow path can be compensated for intermittently by a volume change in the intermittent working area. An Independent claim is also included for a method for operating an internal combustion engine with fuel fed from a fuel system to a fuel injection device.
