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。

摘要： A vane pump includes a casing and a rotary unit rotatably held within the casing. The rotary unit includes a base portion with radially outwardly opened slits extending radially with respect to a rotational axis of the rotary unit and vanes slidably fitted in the respective slits. An annular chamber is formed around the base portion within the casing and divided into a plurality of pump chambers by the vanes. Each of the pump chambers has a volume cyclically expanded and contracted during rotation of the rotary unit to discharge the fluid drawn into each of the pump chambers. The casing includes an inlet port through which to draw the fluid into the annular chamber. The inlet port is arranged to face a portion of the annular chamber extending between a middle position and a terminating position of an expanding section in which each of the pump chambers expands.

摘要： A magnet drive rotary vane pump has a casing with a pump cavity. A rotor carrying a plurality of vanes is disposed within the pump cavity to be rotatable about an eccentric axis with respect to the pump cavity for drawing the fluid into the pump cavity and expelling it out of the pump cavity. The rotor is configured to have a rotor magnet which is magnetically coupled to a stator magnet mounted on the casing outwardly of the pump cavity for driving the rotor. The rotor magnet is configured to have its major portion disposed in an overlapping relation with the stator magnet. Thus, the rotor magnet can be mechanically isolated from the stator magnet disposed outside of the casing to establish a sealless coupling therebetween for realizing leakage free pump.
