Disclosed is a valve-less micro pump configuration that includes plural micro pump elements, each including a pump body having a compartmentalized pump chamber, with plural unobstructed inlet ports and outlet ports and a plurality of membranes disposed in the pump chamber to provide compartments. The membranes are anchored between opposing walls of the pump body and carry electrodes disposed on opposing surfaces of the membranes and walls of the pump body.

A fluid pump for pumping a fluid from an inlet toward an outlet comprises a pump body, a pump diaphragm, and a valve seat. The pump body has a first opening and a second opening. The pump diaphragm is attached to the pump body and forms a pump chamber between the pump body and the pump diaphragm. The pump chamber is fluidly connected to the inlet by the first opening and to the outlet by the second opening. The valve seat is disposed inside the pump chamber and around the second opening. The valve seat protrudes with an undeformed height from the second opening into the pump chamber in a direction toward the pump diaphragm. The valve seat has an elastic body and a gasket with a sealing surface. The pump diaphragm is deflectable and is adapted to open and close a fluidic pathway of the outlet by moving into and out of contact with the valve seat.

A micropump and its use, the micropump including a vibration unit with piezo actuator, which is arranged on an vibration diaphragm, a vibration plate arranged opposite the vibration diaphragm and having a blower opening, as well as a wall arranged between the vibration diaphragm and the vibration plate, so that a blower chamber is formed, and a housing, in which the vibration unit is mounted, with an suction opening, as well as an output opening, which lies opposite the blower opening. The housing forms a closed space and has at least one suction opening arranged radially, or on an underside opposite the vibration unit, with a suction channel leading into a pump chamber located between the vibration plate and the inside of the housing.

Disclosed herein is a dispensable container comprising a container for a fluid; and a fitting for discharging the fluid from the container; wherein the dispensable container is monolithic and where the container and the fitting contact each other seamlessly; and wherein the fitting comprises a conduit that has a higher aspect ratio than the container.

According to examples of the disclosure there is provided a heat-driven pumping system and a method of pumping. The heat-driven pumping system comprises a closed circuit for a first liquid. The closed circuit comprises a vaporization portion. The vaporization portion is configured to receive heat from an external source. The vaporization portion is configured to cause vaporization of first liquid within the vaporization portion. Vaporization of first liquid within the vaporization portion thereby increases an amount of gas in the closed circuit. The closed circuit is sealed such that the increase in the amount of gas increases a pressure exerted on the first liquid. The heat-driven pumping system comprises a transfer means. The transfer means is configured to convert the pressure exerted on the first liquid into a pumping force. The pumping force is transferred to a pumping vessel for pumping a second liquid.

A micropump and its use, the micropump including a vibration unit with piezo actuator, which is arranged on an vibration diaphragm, a vibration plate arranged opposite the vibration diaphragm and having a blower opening, as well as a wall arranged between the vibration diaphragm and the vibration plate, so that a blower chamber is formed, and a housing, in which the vibration unit is mounted, with an suction opening, as well as an output opening, which lies opposite the blower opening. The housing forms a closed space and has at least one suction opening arranged radially, or on an underside opposite the vibration unit, with a suction channel leading into a pump chamber located between the vibration plate and the inside of the housing.

A fluid control device includes a piezoelectric actuator and a deformable substrate. The piezoelectric actuator includes a piezoelectric element and a vibration plate. The piezoelectric element is attached on a first surface of the vibration plate and is subjected to deformation in response to an applied voltage. The vibration plate is subjected to a curvy vibration in response to the deformation of the piezoelectric element. A bulge is formed on a second surface of the vibration plate. The deformable substrate includes a flexible plate and a communication plate stacked on each other. A synchronously-deformed structure is defined by the flexible plate and the communication plate. The deformable substrate is bent in the direction away from the vibration plate. There is a specified depth maintained between the flexible plate and the bulge of the vibration plate. The flexible plate includes a movable part corresponding to the bulge of vibration plate.

A piezoelectric blower includes a housing, top plate, side plate, vibrating plate, piezoelectric element, and cap. The top plate, side plate, and vibrating plate define a blower chamber. The top plate includes a vent hole. The vibrating plate and piezoelectric element constitutes a piezoelectric actuator. The cap includes a wall portion facing the piezoelectric actuator and has a disc-shaped suction port. Here, a central axis of the suction port extending along a thickness direction of the wall portion and a central axis of the piezoelectric element extending along the thickness direction of the wall portion do not coincide with each other. An air channel is provided among the housing, the cap, and a joined structure of the top plate, side plate, and piezoelectric actuator.
