The invention relates to a flat tubular pressure damper (1) for damping fluid pressure oscillations in fluid lines, in particular, fuel pressure oscillations in motor vehicle fuel supply lines. Said damper comprises at least one oblong chamber (24) whose cross-section is small compared to its longitudinal extension, and of which at least a portion of the chamber wall (26) which is actively in contact with the fluid can be elastically deformed by the fluid pressure oscillations. The invention provides that the cross-section of the chamber (24), when viewed along the longitudinal extension of the same, varies continuously or progressively.
(ZH) 本发明涉及已知用于阻尼液体管道内液体压力脉动、特别是汽车燃油供应管道内燃油压力脉动的扁管式压力阻尼器(1),具有至少一个长形室(24),其横截面与其纵向长度相比小,其中至少室壁(26)的一部分与液体处于作用连接地通过液体压力脉动被弹性变形。本发明预定,沿着室(24)纵向长度看,其横截面连续地或者逐级地变化。
