摘要： A compressing diaphragm pump with multiple effects includes an eccentric roundel mount with three cylindrical eccentric roundels, a pump head body with three operating holes, and a diaphragm membrane with three annular positioning protrusions. A basic curved groove or other positioning structure is circumferentially disposed around each operating hole while a basic curved protrusion or other mating positioning structure is provided in the diaphragm membrane for suitably coupling with the corresponding groove or positioning structure in the pump head body upon assembly, resulting in a shortened length of moment arm from the basic curved protrusions or other positioning structures and an annular positioning protrusion, and a reduction in vibration-caused noise and resonant shaking in comparison with a conventional compressing diaphragm pump. The cylindrical eccentric roundels each includes a sloped top ring extending between an annular positioning groove and a vertical or inverted frustoconical flank of the eccentric roundel mount resulting in an extended service lifespan of the compressing diaphragm pump.

摘要： A compressor includes a plurality of synthetic jet assemblies. Each synthetic jet assembly of the plurality of synthetic jet assemblies is in fluid communication with at least one other synthetic jet assembly of the plurality of synthetic jet assemblies. Each synthetic jet assembly of the plurality of synthetic jet assemblies includes a first side plate and a second side plate. The first side plate includes a first bimorph piezoelectric structure. The second side plate includes a second bimorph piezoelectric structure. The first side plate and the second side plate define a first fluid cavity extending between the first side plate and the second side plate.

摘要： An undulatory structure and methods for the fabrication and use thereof. The undulatory structure includes a buckled sheet and one or more work input elements for deforming the buckled sheet in an undulating manner wherein each point in a series of points on a sinuously-shaped profile of the buckled sheet travels at least partially along a figure eight-shaped path. The undulatory structure can be adapted for use as a solid-state transducer wherein the buckled sheet provides mechanical advantage without appreciable opposition from elastic restoring forces, thereby achieving improved force, displacement and efficiency characteristics.

摘要： Provided is a pumping system that includes a parallel dual chamber pumping mechanism and an attachable disposable cassette. The disposable cassette includes a multi-laminate membrane which facilitates efficient, accurate and uniform delivery of fluids. The multi-laminate membrane is held in intimate contact with the pumping fingers of the pumping mechanism by electrostatic or magnetic attraction, thereby allowing the pump to pull a vacuum without the need for a preloaded elastomeric pumping segment.

摘要： A suction pump, in particular a breast pump, comprises a bleed valve with a bleed opening, a bleed body which seals the bleed opening and an operating means for operating the bleed body. The bleed body may be operated such that upon opening the valve initially only a partial region of the bleed opening is released and subsequently a greater part thereof or the whole bleed opening is released. The suction pump provides a large functionality with the smallest size and, furthermore, is cheap to produce and easily assembled.

摘要： An exemplary refill unit for a foam dispenser includes a container for holding a foamable liquid and a liquid pump connected to the container and an outlet nozzle. The liquid pump has a rigid back plate and a flexible membrane. The flexible membrane and the rigid back plate form an arcuate shaped liquid pump chamber. The rigid back plate has a liquid inlet located proximate a first end of the arcuate shaped pump chamber and a liquid outlet located proximate a second end of the arcuate shaped pump chamber. The liquid pump is actuated by progressive compression of the flexible membrane against the back plate.

摘要： A telescopic pump includes a bellow, a cover and a rod. The bellow includes a first end, a second end and a compressible space in communication with exterior of the bellow via the first end. The cover includes a channel in communication with the first end of the bellow. The rod is connected to the second end of the bellow so that the rod is operable to move the bellow between an extended position and a compressed position. The second end of the bellow is far from the first end of the bellow to enlarge the compressible space to suck fluid into the compressible space in the extended position. The second end of the bellow is close to the first end of the bellow to reduce the compressible space to expel the fluid from the compressible space in the compressed position.

摘要： A removable material is deposited or otherwise applied to a flat substrate surface in a pattern corresponding to desired corrugations in a membrane, e.g., a deflection diaphragm. The applied material serves as a scaffold for a polymeric material, which is applied thereover, and following cure or hardening, the polymeric material is removed to form a finished corrugated membrane.
