摘要： A piston carrier supports an elongated, slender piston rod for reciprocation in a pump cylinder to pump fluid into and out of the cylinder. The piston rod is made of a material such as sapphire or zircon and has a diameter less than about ten millimeters, and the pump can provide flows of from about 50 nanoliters to about 250 microliters per minute at pressures of several hundred bars. A drive motor rotates a threaded screw and a drive nut of a drive system applies a linear drive force to the piston carrier. A ball and socket connection between the drive system and the piston carrier avoids the need for precise alignment to prevent breakage of the fragile piston. A magnet in the socket holds the ball in place and avoids the need for a spring or other mechanical holder. The socket also includes a ring of a low reluctance material surrounding the ball to increase the magnetic retention force.

摘要： A pump configured so that tools are not required to remove the pump head and disassemble the plunger. A single large hand operated knob or head nut facilitates tool-less pump head removal. The pump head is guided into position in a manifold and held in place by the hand knob. The manifold is designed to receive all the external fluidic connections made to the pump head. Fluid paths to the pump head have been replaced with miniature face seals which facilitate high pressure sealing between the pump head and manifold. Low pressure tubing seals reside in a seal wash chamber or housing and are not attached to the head, eliminating the need for tooling to disconnect them during pump head removal. A tool-less plunger mechanism includes a nutcap assembly having a plunger socket receiving a plunger assembly including a sapphire plunger fixed to a plunger holder ball accommodated by the socket. The plunger assembly is captured within the socket by a plurality of cams. The cams are spring loaded to rotate and collapse onto the plunger holder ball, pulling the plunger assembly tightly into the socket. A restricting cone is actuated to rotate the cams away from the plunger holder ball for release and removal of the plunger assembly.
摘要翻译：泵被配置为使得不需要工具来移除泵头并拆卸柱塞。单个大型手动旋钮或头螺母便于无需泵头拆卸。泵头被引导到歧管中的位置，并通过手柄保持在适当的位置。歧管设计用于接收与泵头形成的所有外部流体连接。泵头的流体路径已被替换为便于在泵头和歧管之间进行高压密封的微型面密封件。低压油管密封件位于密封清洗室或外壳中，并且不连接到喷头上，因此无需在泵头拆卸过程中切割工具。一种无需工具的柱塞机构包括一个具有活塞插座的螺母盖组件，所述活塞插座接收柱塞组件，所述活塞组件包括固定到由所述插座容纳的柱塞座球的蓝宝石柱塞。柱塞组件通过多个凸轮捕获在插座内。凸轮被弹簧加载以旋转并塌陷到柱塞保持器球上，将柱塞组件紧紧地拉入插座中。致动限制锥以将凸轮转动离开活塞保持器球以释放和移除柱塞组件。

摘要： The pump head liner of a small-size precision reciprocating metering pump, which has its application particularly in High Performance Liquid Chromatography (HPLC), is made of transparent material, preferably of synthetic sapphire or monocrystalline zirconium oxide. A pump head casing is designed such that a pump head liner is visually accessible. Cartridge-type check valve units of transparent components are associated with the pump head casing and pump head liner and mounted to be visually accessible. The opening and closing of a ball in a check valve unit can be monitored by an optical sensing system in order to obtain a feed-back signal for governing a control circuitry, having the purpose of compensating the influence of the specific compressibility of the liquid being pumped, upon the pumping efficiency of the displacement system under conditions of high and highest working pressures.

摘要： The invention relates to devices for transferring or dispensing liquids. Hydraulic positive-displacement device for pumping and/or dispensing fluids, comprising of a working chamber in which the working body is placed, is characterized by the working body made of a composite of at least two parts the first of which—the outside is made of sapphire, and its outer surface is congruent to the interior surface of the working chamber, the second item is placed in the inner cavity of the first part and configured to transmit the translational motion of the working body. The invention reduces the surface roughness of the working body, simplifying the process of replacing individual parts of the unit and extends the range of geometrical sizes of devices that can be manufactured.

摘要： The pump head liner of a small-size precision reciprocating metering pump, which has its application particularly in High Performance Liquid Chromatography (HPLC), is made of transparent material, preferably of synthetic sapphire or monocrystalline zirconium oxide. A pump head casing is designed such that a pump head liner is visually accessible. Cartridge-type check valve units abut onto the pump head liner on the one side, and onto a connecting adapter piece featuring an elbow liquid duct on the other. Pre-loading pressure for liquid sealing is exerted onto the connecting adapter piece by means of a compression screw which is secured in a clamp bracket or L-shaped angled clamping piece. The cartridge-type check valve units can be composed of transparent components and thereby are visually accessible. The opening and closing of a ball in a check valve unit can be monitored by an optical sensing system in order to obtain a feed-back signal for governing a control circuitry, having the purpose of compensating the influence of the specific compressibility of the liquid being pumped, upon the pumping efficiency of the displacement system under conditions of high and highest working pressures. An alternate embodiment has the pump head casing and mounting flange of one-piece construction. The pump head casing has a pair of spaced yoke arms to receive a pump head liner and vertical slots for mounting of check valve modules.
