Abstract:
1. A pulsation damper for damping fluid pressure pulsations of a fluid in a fluid line, comprising: a housing enclosing and defining at least one hollow space therein, the housing having at least one disk shaped attenuator member arranged within the at least one hollow space of the housing, the at least one disk shaped attenuator member having a flow opening extending completely through from an upstream end face of the at least one disk shaped attenuator member to a downstream end face of the at least one disk shaped attenuator member; wherein the at least one disk shaped attenuator member has radially outer contour which substantially corresponds to adjacent inner contour of the hollow space in the housing such that fluid is confined to flow substantially exclusively through the flow opening of the at least one disk shaped attenuator member, preventing bypass of fluid flow around the outer contour of the at least one disk shaped attenuator member; wherein the at least one attenuator member is disposed movably in axial direction within the at least one hollow space; wherein an axial straight line continuous flow channel is formed from the axial inlet port continuing through the at least one disk shaped attenuator member flow opening and continuing to the outlet port, wherein the fluid flows substantially exclusively through the continuous straight line flow channel from the inlet port to the outlet port; wherein the at least one attenuator member flow opening defines a portion of the axial straight line continuous flow channel.
