    • The invention concerns a connection between a largely rigid pipeline and a flexible conduit element by means of a steel nipple, reaching with its one end into the pipeline and with its opposite end into the flexible conduit element, wherein the flexible conduit element is secured to the nipple by means of a clamping sleeve. The basic problem, to configure a flow-favorable connection between a rigid pipeline and a flexible conduit element so that a compact tie-in of the flexible conduit element is possible without the materials being affected by the type of connection technique, is solved in that the pipeline in the segment receiving the nipple and the clamping sleeve are subjected to magnetic pulse shaping coils to reduce a cross section thereof and the pipeline and the nipple have substantially the same inner diameter.
    • 本发明涉及一种通过钢管接头将大体上刚性的管道与柔性管道元件之间的连接,其一端到达管道中,并且其相对端部进入柔性管道元件,其中柔性管道元件固定到 乳头通过夹紧套筒。 基本问题是,在刚性管道和柔性管道元件之间构造一个流动良好的连接,使得柔性导管元件的紧凑的连接可以在材料不受连接技术的类型影响的情况下被解决, 在接收乳头和夹紧套筒的段中的管道经受磁脉冲整形线圈以减小其横截面,并且管道和接头具有基本相同的内径。

    • A connection assembly for the connections of high-pressure pipes in vehicle air conditioning units. The connection assembly includes a connection block having a through channel with a narrowing portion defined by at least one step. A nozzle is located in the through channel of the connection block and the nozzle includes a tapering portion with an exterior surface having at least one step. The narrowing and tapering portions generally correspond with each other and cooperate to define stepped circular gap. A high-pressure pipe extends through the channel outflow region and has a cold deformation end region located in the stepped circular gap, which was forced thereinto upon the nozzle being pressed into the connection block. The hardness of the nozzle is greater than the hardness of the pipe, and the coefficient of thermal expansion of the nozzle is less than the coefficient of thermal expansion of the pipe.
    • 用于车辆空调机组中高压管道连接的连接组件。 连接组件包括连接块,该连接块具有通过至少一个台阶限定的具有狭窄部分的通道。 喷嘴位于连接块的通道中,并且喷嘴包括具有至少一个台阶的具有外表面的锥形部分。 狭窄和渐缩部分通常彼此对应并且协作以限定阶梯状圆形间隙。 高压管延伸穿过通道流出区域,并且具有位于阶梯状圆形间隙中的冷变形端部区域,其在将喷嘴压入连接块时被迫进入其中。 喷嘴的硬度大于管的硬度,喷嘴的热膨胀系数小于管的热膨胀系数。
