摘要： This invention relates to a flexible membrane separation valve, comprising a housing (120), the lateral surfaces of which are provided with slits (121), within which housing (120) a flexible membrane (122) with cylindrical symmetry is housed, within which an insert (130) having a body (131) with cylindrical symmetry is in turn housed, the insert (130) comprising a proximal end (132) having a proximal apex (133) spaced along the longitudinal axis of the insert (130) from a base (134) with cylindrical symmetry, through which the proximal end (132) joins to the body (131), the proximal apex (133) being joined to the base (134) through a continuous surface, the valve being characterized in that the proximal end (132) has an axial section such that tangent lines to the proximal apex (133) form an angle containing the longitudinal axis of the insert that is lower than or equal to 90°. The invention further relates to an apparatus for mixing a liquid comprising such a flexible membrane separation valve.

摘要： A check valve for use in a fluid pathway. The check valve may have a diaphragm and a plurality of supports extending from the diaphragm. The check valve and supports have a line of symmetry, and deformation of the check valve as it moves from a closed position to an opened position can be generally along the line of symmetry.

摘要： Pressure control in fluidic systems is generally described. In some cases, a system comprises a fluid-permeable (e.g., liquid-permeable) medium and a pressure regulator. The medium and the pressure regulator can be positioned between a first fluidic channel and a second fluidic channel. The medium is arranged, in certain cases, such that fluid (e.g., liquid) can be transported from the first fluidic channel, through the medium, and into the second fluidic channel. In certain cases, when a first pressure within the first fluidic channel is below a sum of the permeability pressure differential of the medium with respect to the fluid and a second pressure within the second fluidic channel, the fluid is substantially prevented from being transported through an outlet of the first fluidic channel.

摘要： Valve assembly for a pump, the valve assembly including: a valve seat having a valve face (60), a flexible valve having a sealing portion for abutting the valve face (60), and at least a fluid pathway (66, 68, 70) from an interior of the valve seat to an exterior of the valve seat that serves as a leak flow path for fluid when the valve is in the closed position to reduce pressure build up on the valve. In this way, the vacuum inside the pump can be released when the valve is in the closed position and the pump is stopped, thereby allowing the pump to start/restart due to reduced pressure build up on a side of the valve abutting the valve face. A pump or compressor including such a valve assembly is also disclosed.

摘要： It is described an ink cartridge for an ink jet recording apparatus such as an ink jet printer that is provided with a container (1) having at least a first wall (1a). An ink supply port (2) is formed through the first wall (1a) for supplying ink to the exterior of the container (1). An ink chamber (4) and an ink supply chamber (5) are formed by a membrane valve seat (3) made of an elastic thin membrane and formed with a through hole (6) therethrough. A valve body (8) is positioned opposing the through hole (6) formed in the membrane valve seat (3), the valve body (8) and membrane valve seat (3) adjacent said through hole (6) formed therein being maintained selectively in contact by a pressure difference between said ink chamber (4) and said ink supply chamber (5).

摘要： An irrigation appliance uses a reservoir which inverts to form a cover (32) and includes a simplified valve (40) in the reservoir as well as a switching mechanism (72) adapted thereto. Liquid delivered to the unit from the reservoir is controlled as to pressure by adjustment on a hand-held device remote from the unit. In the base unit are elements which regulate forward and backward flow in order to obtain outlet pressure control.
