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.

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。

Raised-face seat. A groove around the seat collects particles pushed aside by the knife and prevents clogging. When the valve opens, media pressure cleans the groove.

凸面阀座。阀座周围的槽将颗粒收集起来，并排挤到闸刀旁边，以避免出现堵塞。当阀门开启时，流体介质压力就会清洗槽内的颗粒。

The results of calculation indicates that the static axial stiffness of fluid film in double spiral groove face seal is improved due to the pressure loss through feeding holes.

计算结果表明， 供液小孔所产生的压力损失提高了双列螺旋槽机械密封的静态轴向刚度。

Worse, now that their bad technique still produced good shots, poor players had less incentive to put in the hard work needed to groove mechanically sound, pressure-proof and ultimately satisfying swings.
