    • The invention relates to an apparatus for absorbing the sound of a medium which flows through a tubular channel, has pulsating pressure differentials and has, at least in sections, a proportion which rotates about the longitudinal axis of the tubular channel, wherein the rotational speed of the medium is proportional, from the centre of the rotation radially to the outside, to the radial spacing from the rotational centre, characterized in that the tubular channel has at least two tubular-channel sections (1, 2) 15, wherein the first tubular-channel section (1) is arranged ahead of the second tubular-channel section (2) in the flow direction and the first tubular-channel section (1) has a predefined flow cross-sectional area (8) which is greater than the flow cross-sectional area (11) of the second tubular-channel section (2), and the ratio of the flow cross-sectional area (8) of the first tubular-channel section (1) and the flow cross-sectional area (11) of the second tubular-channel section (2) is selected in such a way that, during the passage from the first tubular-channel section (1) into the second tubular-channel section (2), the rotating medium can be accelerated in the rotational direction proportionally to the rotational speed and in the process the axial speed of the rotating medium can be reduced proportionally to the rotational acceleration of the medium.
    • 本发明涉及一种用于吸收流过管状通道的介质的声音的装置,其具有脉动压力差并且至少以分段形式具有围绕管状通道的纵向轴线旋转的比例,其中, 所述介质从径向到外部的旋转的中心成比例到与所述旋转中心的径向间隔成比例,其特征在于,所述管状通道具有至少两个管状通道部分(1,2)15,其中所述第一管状 - 通道部分(1)在流动方向上布置在第二管状通道部分(2)的前方,并且第一管状通道部分(1)具有大于流动的预定的流动横截面积(8) 第二管状通道部分(2)的横截面积(11)和第一管状通道部分(1)的流动横截面积(8)与流动横截面积(11)之比 )的第二管状通道 选择部分(2),使得在从第一管状通道部分(1)到第二管状通道部分(2)的通道期间,旋转介质可以沿与旋转方向成比例的旋转方向加速 速度,并且在该过程中,旋转介质的轴向速度可以与介质的旋转加速度成比例地减小。

    • The invention relates to a connector arrangement for fluid lines (1, 2) comprising a further fluid transporting component (16), wherein the fluid line (1, 2) has at least one collar (3, 4), facing radially outwards which may be tensioned against the further fluid transporting component (16) by means of a retainer (5). The retainer (5) for the connector arrangement comprises at least one U-shaped lateral housing (6, 7) formed by two legs (12), the predetermined length of the legs (12) being such as to enclose more than half of the fluid line (1, 2) on plastic deformation. The U-shaped housing (6, 7) comprises at least one relieving region (13) in which holes, grooves cavities or other material reductions are arranged. The cross-section fo the legs (12) changes little on deformation due to the relieving regions as swaged material can flow into the same.
    • 本发明涉及一种用于包括另一流体输送部件(16)的流体管线(1,2)的连接器装置,其中流体管线(1,2)具有至少一个径向向外朝向的凸缘(3,4),其可以 通过保持器(5)抵靠所述另外的流体输送部件(16)张紧。 用于连接器装置的保持器(5)包括由两个腿部(12)形成的至少一个U形横向壳体(6,7),腿部(12)的预定长度包围超过 流体管线(1,2)塑性变形。 U形壳体(6,7)包括至少一个释放区域(13),其中布置有孔,凹槽腔或其他材料减少部。 由于模锻材料可以流入其中,所以腿部(12)的横截面由于释放区域而变形很小。
