Beschreibung
Zusammenfassung:	The pressure pulse damper for a dosing pump (10), especially a fuel metering pump, comprises a compressible pulse damping component (28) around which flows the pressurized medium which is to be delivered. The pulse damping component is a hollow body of flexible material with a sealed cavity (32) filled with a compressible medium such as gas. The damping component is installed in a housing, with a flow chamber formed between the inner surface and pulse damping body. An independent claim is included for a dosing pump, and especially a fuel metering pump for motor vehicles, equipped with the proposed pressure pulse damper. Ein Druckpulsationsdämpfer für eine Dosierpumpe, insbesondere Kraftstoffdosierpumpe, umfasst einen von einem unter Druck zu fördernden Medium umströmbaren, kompressiblen Pulsationsdämpfungskörper (28).
