摘要： An annular tube (or other shape) of elastomeric cellular material comprising elastomeric closed cells having gas infused therein is supported by structures protruding from the bottom surface of a suction stabilizer's head and/or by structures within the interior volume of the annular body of the suction stabilizer, preferably with spacing between the outer diameter of the annular tube of the cellular material and the inner walls of the suction stabilizer body. The gas-infused closed cell material may thus be employed in new suction stabilizer or pulsation dampener or to retrofit existing suction stabilizers or pulsation dampeners designed for a gas-filled bladder.

摘要： A system includes a sorting chamber and a fluid channel in fluid communication with the sorting chamber. A peristaltic pump is in fluid communication with the fluid channel to pump fluid through the fluid channel to the sorting chamber at a fluid flow rate. A fluid damper is in fluid communication with the sample fluid channel. The fluid damper includes a gas and reduces variations in the fluid flow rate by compression and expansion of the gas in response to fluid flow in the fluid channel.

摘要： In a liquid discharge control apparatus which uses a piezoelectric type diaphragm pump, an accumulator having a liquid accumulation cavity and a movable member is communicated to an outlet of the diaphragm pump. In discharge operation of the diaphragm pump, a quantity of the liquid in the liquid accumulation cavity is rapidly increased, and the movable member is elastically deformed so as to increase of the volume of the liquid accumulation cavity. Alternatively, in suction operation, when a back stream of the liquid occurs, the quantity of the liquid in a path communicated to the outlet of the diaphragm pump is decreased due to the back stream. The decrease of the liquid can be compensated by the decrease of the volume of the liquid accumulation cavity of the accumulator. Thereby, variation of the quantity of the liquid discharged from the outlet of the accumulator is reduced and the liquid can be discharged, smoothly.
摘要翻译：在使用压电式隔膜泵的液体排出控制装置中，具有液体积聚腔的蓄液器和可动构件与隔膜泵的出口连通。在隔膜泵的排出操作中，液体积聚腔中的液体量迅速增加，并且可动件弹性变形，从而增加了液体积聚腔体积。或者，在抽吸操作中，当发生液体的回流时，与隔膜泵的出口相通的路径中的液体量由于回流而降低。液体的减少可以通过蓄能器的液体积聚腔体积的减小来补偿。由此，从蓄液器的出口排出的液体的量的变化减少，液体可以平稳地排出。
