    • A mechanism allows for changing the optical strength of a liquid-filled lens having a cavity filled with fluid. A reservoir contains additional fluid and is in fluid communication with the cavity, and the mechanism draws fluid from the reservoir into the cavity or pulls fluid from the cavity back into the reservoir, whereby a change in the amount of fluid within the lens cavity changes the lens's optical strength. A membrane seals the reservoir, and a plunger impinges upon the membrane. A movement device, such as a barrel screw or lever, moves the plunger in a controlled manner toward the membrane to increase pressure within the reservoir and thereby force fluid out of the reservoir into the lens cavity, and away from the membrane to decrease pressure within the reservoir and thereby withdraw fluid from the lens cavity and into the reservoir.
    • 机构允许改变填充有流体的腔的充满液体的透镜的光学强度。 储存器包含额外的流体并且与空腔流体连通,并且机构将流体从储存器抽入空腔中或将流体从空腔拉回到储存器中,由此透镜腔内的流体的量的改变使得 镜头的光学强度。 膜密封储存器,柱塞冲击膜。 诸如桶形螺杆或杠杆的移动装置以可控的方式将柱塞移动到膜上以增加储存器内的压力,从而将流体从储存器流出到透镜腔中,并且远离膜以降低压力 储存器,从而从透镜腔中抽出流体并进入储存器。
