后方纾缓压力槽是必要的,为稳定和清晰可见。
The rear stress relief grooves are necessary for stability and are visible.
除了平衡涡旋内部压缩气体压力以外,还提供了顶端和底槽间的密封力,该密封力靠浮动密封圈来实现。
In addition to balance vortex internal pressure of compressed gas beyond, still provides top and bottom sealing force between the slot, the sealing force to achieve by floating sealing ring.
此外,蜗杆的蜗杆槽深度随压力的增高而减少,在排气结束,星轮齿脱离单槽时,深度为零,故不存在余隙容积。
In addition, the worm and worm groove depth of the pressure increased, in the end, reduce exhaust gate-rotor from the single slot, depth is zero, it does not exist.
