    摘要： A pump contains a sealed chamber, a movable wall for changing a volume of the sealed chamber, and a vibration actuator which can be electromagnetically driven for displacing the movable wall to discharge fluid in the sealed chamber to an outside of the sealed chamber. Further, three axes perpendicular to each other are respectively defined as an X axis, a Y axis, and a Z axis. When a direction along the X axis is defined as an X axis direction, a direction along the Y axis is defined as a Y axis direction, and a direction along the Z axis direction is defined as a Z axis direction, an outer shape of the pump is a concave shape in a planar view from the Y axis direction.

    摘要： This vibration actuator comprises a fixed body including a coil, a movable body including a magnet, and an elastic support part that supports the movable body so as to be freely moveable with respect to the fixed body, wherein the coil to which power is supplied and the magnet cooperate to cause the movable body to vibrate with respect to the fixed body. The elastic support part has an outer circumferential part bonded to the fixed body, an annular inner circumferential part disposed inside in the radial direction of the outer circumferential part and bonded to the movable body, and a deforming arm part that couples the outer circumferential part and the inner circumferential part and is elastically deformable. The elastic support part has a sealing part provided in a bonding part between the inner circumferential part and the movable body to seal the bonding part.

    摘要： This vibration actuator has a movable body having a coil, a fixed body having magnets, and a shaft part that rotatably supports the movable body, wherein the movable body reciprocally and rotationally vibrates around the shaft part with respect to the fixed body through the interaction of the coil and the magnets. The magnets are arranged in a direction perpendicular to the axial direction of the shaft part and each have two magnetic poles that face the movable body in the coil axial direction of the coil, the shaft part supports the movable body at a position shifted from the center position of the movable body in a direction perpendicular to the axial direction of the shaft part, and the coil axis of the coil of the movable body is located at a position facing a switching position of the magnetic pole of the magnet.

    摘要： A pump contains a pump unit for suctioning and discharging fluid due to electromagnetic drive of a vibration actuator. The vibration actuator includes a fixed body containing one of a coil core portion and a magnet, a movable body containing another one of the coil core portion and the magnet, and a shaft portion for supporting the movable body so that the movable body can perform reciprocating rotation. The pump unit includes a movable wall, and a sealed chamber whose volume can be changed by displacement of the movable wall. The movable body has a pressing portion which can abut against the movable wall to press the movable wall when the movable body performs the reciprocating rotation.

    摘要： A pump control device controls a pump including a vibration actuator for vibrating a vibrating body due to electromagnetic drive caused by electrical current supply to coils, a sealed chamber which includes a movable wall which can be displaced by vibration of the vibrating body so that fluid can be suctioned into an inside of the sealed chamber or discharged from the inside of the sealed chamber, and a discharge portion for communicating the fluid between the sealed chamber and a tank to increase pressure of the fluid. The pump control device contains an obtaining part for obtaining pressure value information, and a control unit for controlling a drive frequency of an electrical current to be supplied to the coils based on the obtained pressure value information.

    摘要： This vibration actuator has: a stationary body having a coil; a movable body having a magnet disposed radially inside the coil; and an elastic support part for supporting the movable body so that the movable body can move relative to the stationary body. The stationary body has a coil holding part. The coil holding part has, on the inner diameter side of the coil, a coil protection wall part. The elastic support part has at least two or more plate springs bridged between the coil holding part and the movable body so as to sandwich the movable body in a vibration direction. In order that the movable body does not come into contact with the coil holding part when not vibrating and when vibrating, the plate springs support the movable body so that the movable body is movable in the vibration direction.
