Attenuator capsule, pressure pulsation attenuator, and high pressure fuel pump

摘要

Various embodiments may include a damper capsule comprising: a damping volume including a diaphragm having a deformation region deformable along a deformation axis by pressure pulsations and a connecting region; and a closure element for closing off the damping volume and connected to the diaphragm by a closure element. The diaphragm includes a profile region forming a spacer for separating the deformation region, in the direction of the deformation axis, from holding elements which hold the damper capsule when the damper capsule has been installed. The deformation region, the connecting region, and the profile region comprise a unipartite diaphragm component.
