    • A nozzle (100) comprises a nozzle housing (112) having a preload engagement surface (159), a nozzle tip, a tip retainer (124) having a preload engagement surface (159) that retains the nozzle tip against the nozzle housing (112), and a preload limiter gap (170) between the tip retainer (124) and the nozzle housing (112) comprising a spaced distance between the preload engagement surfaces (159) when the nozzle (100) is in a first position and a second position that creates a desired amount of preload force when the nozzle (100) is in the second position. In another embodiment, a nozzle (100) comprises a nozzle housing (112), a nozzle tip, and a tip retainer (124) moveable with respect to the nozzle tip along the nozzle housing (112) and that retains the nozzle tip against the nozzle housing (112). A tapered interface disposed between the tip insert and the tip retainer (124) at an angle greater than or less than 90 degrees with respect to a longitudinal axis of the nozzle (100).
    • 喷嘴(100)包括具有预压接合表面(159)的喷嘴壳体(112),喷嘴尖端,具有将喷嘴头保持在喷嘴壳体(112)上的预压接合表面(159)的尖端保持器 )和在所述尖端保持器(124)和所述喷嘴壳体(112)之间的预加载限制器间隙(170),其在所述喷嘴(100)处于第一位置时包括所述预压接合表面(159)之间的间隔距离, 当喷嘴(100)处于第二位置时产生期望量的预紧力的位置。 在另一个实施例中,喷嘴(100)包括喷嘴壳体(112),喷嘴尖端和尖端保持器(124),其能够沿着喷嘴壳体(112)相对于喷嘴尖端移动并且将喷嘴尖端保持在喷嘴壳体 喷嘴壳体(112)。 锥形界面相对于喷嘴(100)的纵向轴线以大于或小于90度的角度设置在尖端插入件和尖端保持器(124)之间。
