摘要： A gas transportation device (1) includes an inlet plate (17), a substrate (11), a resonance plate (13), an actuating plate (14), a piezoelectric component (15) and an outlet plate (16) stacked sequentially. The gas transportation device (1) includes a valve (10) disposed within at least one of the inlet (170) of the inlet plate (17) and the outlet (160) of the outlet plate (16). A first chamber (18) is formed between the resonance plate (13) and the actuating plate (14), and a second chamber (19) is formed between the actuating plate (14) and the outlet plate (16). When the piezoelectric component (15) drives the actuating plate (14), a pressure gradient is formed between the first and second chambers (18, 19) and the valve (10) is opened. Accordingly, gas is inhaled into the convergence chamber (12) via the inlet (170), transported into the first chamber (18) through a central aperture (130) of the resonance plate (13), transported into the second chamber (19) through a vacant space (143) of the actuating plate (14), and then discharged out from the outlet (160), so as to transport the gas.

摘要： An object is to provide a piezoelectric micro-blower capable of efficiently conveying compressive fluid without use of a check valve and ensuring a sufficient flow rate. A blower body 1 has a first wall 1a and a second wall 1b. Openings 5a and 5b are formed in parts of the respective walls, the parts facing a center of a diaphragm 50. An inflow path 7 allowing the openings 5a and 5b to communicate with the outside is formed between the walls. By applying a voltage to a piezoelectric element 3 to cause the diaphragm 50 to vibrate, a part of the first wall 1a vibrates, the part being close to the first opening 5a. Thus, gas can be drawn from the inflow path 7 and discharged from the opening 5b.

摘要： A fluid control device includes a piezoelectric actuator (2), a housing (1) and a glue body (5). The piezoelectric actuator (2) includes a suspension plate (21), an outer frame (23), a bracket (24) and a piezoelectric element (22). The housing (1) includes an outlet plate (11) and a base (12). The outlet plate (11) accommodates the piezoelectric actuator (2) and the base (12) includes an inlet plate (121) and a resonance plate (122). The glue body (5) is arranged between the outer frame (23) and the resonance plate (122) to maintain a gap (h) formed therebetween. The suspension plate (21) is made of a material having a linear expansion coefficient less than a linear expansion coefficient of the piezoelectric element (22). The suspension plate (21) has a specified hardness to maintain curved after being heated, and the linear expansion coefficient of the suspension plate (21) is different from a linear expansion coefficient of the resonance plate (122), so that an effective deformation displacement (δ) between the suspension plate (21) and the resonance plate (122) is obtained.

摘要： A micro pump is formed on a substrate having a common inlet channel and a common outlet channel by a plurality of pumping elements, each pumping element having an inlet coupled to the common inlet channel and an outlet coupled to the common outlet channel, the inlet and outlet connected by a microfluidic channel, the microfluidic channel comprising a valvular conduit having low fluid flow resistance in a direction from the inlet to the outlet and high fluid flow resistance in a direction from the outlet to the inlet, and an actuating element arranged to cause fluid to be pumped through the microfluidic channel from the inlet to the outlet, wherein the actuating element is based on one or more of piezoelectric, thermal, electrostatic or electromagnetic transduction. A controller is coupled to actuate the actuating elements at mutually staggered relative timing so as to produce a substantially continuous steady flow.

摘要： A personal air sampling pump assembly includes a motor having a reciprocating piston for operating a diaphragm assembly. The diaphragm includes a valve head including a fluid inlet and a fluid outlet and a fluid chamber defining a fluid path between the inlet and outlet. A first and second diaphragm sealing engaging the valve head and enclosing the fluid chamber. The first diaphragm includes a piston diaphragm membrane portion coupled to the piston for reciprocating with the piston and wherein reciprocation of the piston causes a change in air pressure within the fluid chamber to cause air to move from the fluid inlet toward the fluid outlet. Both the first and second diaphragms include a damper membrane portion, which cooperate to reduce an amplitude of pulsation in the airflow at the fluid inlet and fluid outlet.
