Pressure energizing ferrule for high pressure droplet generator nozzle

A capillary retention system is disclosed that includes a pressure energizing ferrule that is double sealed and is configured and arranged such that an internal target material pressure acts to increase the sealing pressure. According to another aspect of one embodiment, the pressure energizing ferrule is configured and arranged such that the sealing contact pressure on the capillary is closer to the free surface 5 of the capillary constituting the nozzle outlet and thus the free length of the capillary is reduced, thereby increasing the bending pattern of the capillary so that it is less likely to be energized by system vibrations. 公开了一种毛细管保持系统，该毛细管保持系统包括压力激励套圈，该压力激励套圈是双重密封的并且被配置和布置成使得内部目标材料压力起到增加密封压力的作用。根据一个实施例的另一方面，压力激励套圈被配置和布置成使得毛细管上的密封接触压力更靠近构成喷嘴出口的毛细管自由面5，并因此减小毛细管自由长度，进而增加毛细管的弯曲模式，从而使其不太可能被系统振动激励。
