摘要： In a fluid control device, a check valve includes a first valve housing and a first diaphragm. The first diaphragm defines a first valve chamber and a second valve chamber. An exhaust valve includes a second valve housing and a second diaphragm. The second diaphragm defines a third valve chamber and a fourth valve chamber. The check valve is opened and closed by a difference in pressure between the first valve chamber and the second valve chamber. The exhaust valve is opened and closed by a difference in pressure between the third valve chamber and the fourth valve chamber.

摘要： A valve includes: a first plate having a first vent hole; a second plate having a second vent hole; a valve chamber positioned between the first plate and the second plate; a valve body including a third vent hole; an exhaust path-forming plate forming a first flow path between the exhaust path-forming plate and the valve body, forming a second flow path between the exhaust path-forming plate and the second plate, and having a fourth vent hole through which the first flow path is in communication with the second flow path; and a fifth vent hole. The first flow path establishes communication between the second vent hole and the fourth vent hole, and the second flow path establishes communication between the fourth vent hole and the fifth vent hole.

摘要： A pump (1) includes a vibrating plate (15) that has a central part (21), a frame part (22), and connecting parts (23 to 26), a piezoelectric element (16) that is stacked over the central part (21) and configured to cause flexural vibrations to occur concentrically from the central part (21) to the connecting parts (23 to 26), and an opposed plate (13) that is stacked over the frame part (22) and positioned facing each of the connecting parts (23 to 26) with a spacing therebetween. The vibrating plate (15) has such a resonant mode that an antinode occurs in each of the central part (21) and the connecting parts (23 to 26). The opposed plate (13) has, at positions facing the connecting parts (23 to 26), a plurality of channel holes (39 to 43) through which a fluid flows.

摘要： A fluid control device includes a vibrating plate unit, a driver, and a flexible plate. The vibrating plate unit includes a vibrating plate with first and second main surfaces, a frame plate surrounding the vibrating plate, and a link portion linking the vibrating plate and the frame plate and elastically supporting the vibrating plate against the frame plate. The driver is on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate having a hole faces the second main surface of the vibrating plate, being fixed to the frame plate. At least a portion of the vibrating plate and the link portion are thinner than the thickness of the frame plate so that the surface of the portion of the vibrating plate and the link portion, on the side of the flexible plate, can separate from the flexible plate.

摘要： A piezoelectric pump includes a leaf spring including a disc portion defining an actuator, an outer frame portion defining a housing, and an elastic support portion. The actuator flexurally vibrates from a center portion of a principal surface thereof to an outer periphery thereof. The elastic support portion includes a beam portion and connection portions and elastically supports the disc portion on the outer frame portion. The beam portion extends in a gap between the disc portion and the outer frame portion in a direction along an outer periphery of the disc portion. A first of the connection portions connects the beam portion to the disc portion. Second and third connection portions are offset from the first connection portion and connect the beam portion to the outer frame portion.

摘要： A valve includes a housing, a membrane, and a hole. The housing includes a flat plate having a hole connectable to an external pump, a housing component having a hole connectable to a component to which a fluid is discharged, and a valve chamber held between a housing component including the flat plate and the housing component. The membrane divides a valve chamber into a space facing the flat plate and a space facing the housing component. The hole is connected to the space facing the flat plate and the space facing the housing component. The housing component has a hole that is connectable to an outside of the housing and that allows the fluid to flow out from the valve chamber.

摘要： A pump apparatus includes a piezoelectric pump, an outer housing, and an adhesive sheet. The piezoelectric pump has a principal surface at which a discharge port for a fluid is formed. The outer housing has a housing channel that communicates with the discharge port, and the outer housing is formed at least partially using a resin having water-containing properties. The adhesive sheet adheres the principal surface of the piezoelectric pump to the outer housing. The outer housing includes a main plate. The main plate has a principal surface that opposes the principal surface of the piezoelectric pump and is in contact with the adhesive sheet. The main plate also has a through-hole that communicate with the discharge port and with the housing channel. The principal surface is formed as a surface of a metal portion.
