A fluid control apparatus includes a piezoelectric pump and valve. The valve includes a second valve housing, second seal member, diaphragm, first seal member, and first valve housing and has a structure in which they are laminated in sequence. The first valve housing includes a second vent and third vent, has a valve seat, and includes six cavities. The second valve housing has a first vent and first vent and includes a valve seat and six first protrusions. The second valve housing further includes six second protrusions nearer the outer edges than the six first protrusions, as seen in the x-axis direction in plan view.

A valve includes a first valve housing, a second valve housing, a diaphragm, a first fixing part, and a second fixing part. The diaphragm defines an upstream valve chamber together with the first valve housing. The diaphragm defines a downstream valve chamber together with the second valve housing. The diaphragm is movable between a first position in which the diaphragm blocks communication between the upstream valve chamber and the downstream valve chamber, and a second position in which the diaphragm allows communication between the upstream valve chamber and the downstream valve chamber. When in its second position, the diaphragm makes contact with the inlet of the second discharge channel or the wall surface of the downstream valve chamber to seal between the second discharge channel and the first discharge channel, and when in its first position, the diaphragm allows communication between the first discharge channel and the second discharge channel.

A cassette integrated system. The cassette integrated system includes a mixing cassette, a balancing cassette, a middle cassette fluidly connected to the mixing cassette and the balancing cassette and at least one pod. The mixing cassette is fluidly connected to the middle cassette by at least one fluid line and the middle cassette is fluidly connected to the balancing cassette by at least one fluid line. The at least one pod is connected to at least two of the cassettes wherein the pod is located in an area between the cassettes.

A disposable container for solvent contaminated wipes and a method of using the disposable container to prevent solvent contaminated wipes from spontaneously combusting is disclosed. The disposable container may be a flexible bag made of a material having a solvent-resistant, non-permeable layer and optionally other layers. The disposable container has an oxygen-reduction system including an air-tight seal, which may be formed in a variety of ways, and an oxygen-removal mechanism, such as a small pump that is integral to the flexible bag or a pump outlet that can be connected to an external pump.

A plate or check valve, for diaphragm pumps, including a valve chamber in which at least one valve seat is provided that interacts with a valve plate that is elastically pretensioned via outer edge mountings such that a closing body of the valve plate can be moved from a closed position, in which it sealingly lies on the valve seat, into an open position against the elasticity of the valve plate. The outer edge mountings have webs and connecting brackets which are connected to the web ends facing away from the closing body. The outer edge mountings are disconnected from one another and only engage on the closing body, each of the outer edge mountings has at least two webs that are connected together via a connecting bracket, and each connecting bracket engages behind at least one paired holding base of the valve housing.

A cassette integrated system. The cassette integrated system includes a mixing cassette, a balancing cassette, a middle cassette fluidly connected to the mixing cassette and the balancing cassette and at least one pod. The mixing cassette is fluidly connected to the middle cassette by at least one fluid line and the middle cassette is fluidly connected to the balancing cassette by at least one fluid line. The at least one pod is connected to at least two of the cassettes wherein the pod is located in an area between the cassettes.

A rapid-discharge-valve structural body (2) allows air to flow from an input-side space (9A) to an output-side space (9B) in accordance with the flow rate of air to be supplied to a supply passage (101). Accordingly, the flow rate of air to be discharged from a discharge passage (113) also changes. As a consequence, flow rate peaking can be prevented.

The valve includes a second valve housing, second seal member, diaphragm, first seal member, and first valve housing and has a structure in which they are laminated in sequence. The first valve housing includes a second vent and third vent, has a valve seat, and includes six cavities. The second valve housing has a first vent and first vent and includes a valve seat and six first protrusions. The second valve housing further includes six second protrusions nearer the outer edges than the six first protrusions, as seen in the x-axis direction in plan view.
