摘要： Since many valves are used, pressure loss is large, resulting in low reliability of a pump. Even when the period of increasing and decreasing the volume of a pump chamber is long, and a piezoelectric element is used as an actuator that drives a diaphragm, a driving operation cannot be performed at a high frequency, or a proper flow rate cannot be realized under a high load pressure. In accordance with the invention, the combined inertance value of an entrance passage used to make working fluid flow into a pump chamber is smaller than the combined inertance value of an exit passage used to make the working fluid flow out from the pump chamber. A fluid resistance member is provided at the entrance passage in which fluid resistance when the working fluid flows into the pump chamber is smaller than fluid resistance when the working fluid flows out of the pump chamber.

摘要： The invention provides a pump which has reduced pressure loss by using fewer mechanical on-off valves, which has increased reliability, which can be used under a high load pressure, which can be driven at a high frequency, and which has good drive efficiency by increasing discharge fluid volume per pumping period. A circular diaphragm, disposed at the bottom portion of a case, has its outer peripheral edge secured to and supported by the case. A piezoelectric device to move the diaphragm is disposed at the bottom surface of the diaphragm. A space between the diaphragm and the top wall of the case is a pump chamber. An inlet flow path, having a check valve serving as a fluid resistor disposed thereat, and an outlet flow path, which opens to the pump chamber during operation of the pump, open towards the pump chamber. In the pump, driving of the piezoelectric device is controlled so that an average displacement velocity in a pump chamber volume reducing step of the diaphragm becomes a velocity at which the diaphragm reaches the reached-displacement-position in a time equal to or less than ½ and equal to or greater than 1/10 of a natural vibration period T of fluid inside the pump chamber and the outlet flow path.

摘要： A pair of flexible actuators according to the present invention is supported by a fixture made of a hard rubber at base ends of the flexible actuators. Each flexible actuator includes a movable unit that is capable of bending, a pump unit integrally connected to the movable unit at an end thereof, to control transfer of work fluid sealed in the movable unit, and a pump driver that controls driving of the pump unit. The movable unit includes two long and narrow tubes that each have an accordion wall, a core that maintains the tubes in parallel with each other, and a thin-film-bag-like cover that covers the tubes. The tube, which comes into contact with an object, is made of a soft material. The movable unit that is provided with the tube softly comes into contact with the object at a plurality of plane-contact portions of action of the movable unit, thereby holding the object without scratching the same.
