摘要： A vane type hydraulic energy translating device for pumping filtered seawater and which uses seawater as a lubricating fluid. The pump is a compact, light weight design in which the bearings and certain other critical components are fabricated from corrosion resistant, low friction, high strength materials. The vanes as well as flexible side plate members are formed of these corrosion resistant materials. The pump body is formed of high corrosion resistant stainless steel. The side plates are flexible and act as wear surfaces for the ends of the vanes as well as sealing surfaces about the rotor thereby preventing leakage of seawater from high to low pressure areas. Each vane is spring biased radially outward from the rotor axis with four springs disposed within apertures located in the vane base. The vanes are generally rectangular in shape and have an outer end portion which serves as a sliding seal against a cam ring track. The rotor of the pump is uniquely splined to the shaft such that axial forces along the shaft do not translate to the rotor. A unique under vane pressurization system facilitates the passage of pressurized seawater to the base of the vane to assist in urging the vane radially outward against the cam track ring.
摘要翻译： 用于泵过滤海水的叶片型液压能量转换装置，其使用海水作为润滑液。 泵是一种紧凑，重量轻的设计，其中轴承和某些其他关键部件由耐腐蚀，低摩擦，高强度材料制成。 叶片以及柔性侧板构件由这些耐腐蚀材料形成。 泵体由高耐腐蚀不锈钢制成。 侧板是柔性的，并且用作叶片的端部的磨损表面以及围绕转子的密封表面，从而防止海水从高压区域泄漏到低压区域。 每个叶片是从转子轴线径向向外偏压的弹簧，四个弹簧设置在位于叶片基座内的孔内。 叶片的形状通常为矩形，并且具有用作抵靠凸轮环轨道的滑动密封件的外端部分。 泵的转子独特地花键连接到轴上，使得沿着轴的轴向力不会转移到转子。 独特的叶片下加压系统有助于加压海水通向叶片的底部，以帮助推动叶片径向向外抵靠凸轮轨道环。

摘要： A seawater hydraulic rock drill having a trigger which when engaged by a diver allows pressurized seawater to be directed through an open supply poppet valve assembly into a drive chamber having a plunger. The pressurized seawater drives the plunger into a piston, an anvil, and a drill bit creating a percussive impact into a rock surface breaking up the rock surface. At the same time pressurized seawater exits the drive chamber through an orifice into a reversible seawater hydraulic motor which rotates the drill bit thereby pulverizing the broken rock. As the plunger approaches the end of a drive cycle, the supply poppet is pressurized closing the supply poppet valve assembly and cutting off the flow of seawater to the drive chamber. Pressurized seawater then drives the piston and plunger to their initial positions, the supply poppet valve assembly opens, and the cycle is repeated.
摘要翻译： 具有触发器的海水液压凿岩机，当由潜水员接合时，允许加压海水通过打开的供给提升阀组件被引导到具有柱塞的驱动室中。 加压海水将柱塞驱动到活塞，砧座和钻头中，从而在破坏岩石表面的岩石表面上产生冲击冲击。 同时，加压海水通过孔口离开驱动室，进入旋转钻头的可逆海水液压马达，从而粉碎破碎的岩石。 当柱塞接近驱动循环的结束时，供给提升阀被加压，从而关闭供给提升阀组件并切断海水流到驱动室。 加压海水然后将活塞和柱塞驱动到其初始位置，供应提升阀组件打开，循环重复。
