Abstract

The pulsation damper (10) for a feed pump has a housing with a flexible membrane closing one end and defining a pressure chamber (24) of variable volume The chamber is connected to a gas source by a switching valve. The membrane has a position adjuster to allow movement between end positions dependent on the fluid pressure. The membrane is connected to a rod which carries a permanent magnet and there is a sensor to determine the membrane position and alter the switching valve or vent valve to regulate the membrane.
