Abstract:
This invention relates to a magnetically actuated valve (60), in particular for a mixing apparatus, comprising mechanical means (50, 51, 53, 62) for opening and closing the valve (60), at least one ferromagnetic metal pin (52) mobile between a rest position and an operating position, and at least one activation magnet (61) mobile between a first position and a second position, said mechanical means (50, 51, 53, 62) being capable to interact with said at least one ferromagnetic metal pin (52) for opening and closing the valve (60), said at least one activation magnet (61) being capable to magnetically interact with said at least one ferromagnetic metal pin (52), the valve (60) being characterised in that it comprises sliding mechanical means (63, 64, 65, 66, 67, 68) comprising a slide (63) integrally coupled to said at least one activation magnet (61) and mobile between an initial position and a final position. This invention further relates to an apparatus for mixing a liquid comprising such magnetically actuated valve (60).
Abstract:
A valve assembly comprising m adapter plate assembly comprising m adapter plate, a bonnet with a center and a threaded shall extending through the center of the bonnet; an actuation assembly comprising an outer enclosure and an outer magnetic cartridge that is magnetically coupled to an inner magnetic cartridge; and an inner valve assembly comprising an Inner enclosure and a planetary gear subassembly comprising one or more planetary gears.
Abstract:
A stemless ball valve comprising two flanges and a ball with a channel, two axis pins and two travel pins. One end of each axis and travel pin is fixedly attached to the ball, and the other end of each axis pin is lodged into a notch in the first or second flange such that the axis pin is allowed to rotate in the notch. The guide sleeve comprises two channels, and one end of each travel pin is situated within one of the two channels in the guide sleeve. An outer magnetic cartridge causes the inner magnetic cartridge and guide sleeve to rotate, and when the guide sleeve rotates, the travel pins move up and down within the channels in the guide sleeve. The movement of the travel pins within the channels in the guide sleeve causes the ball to rotate, thereby opening and closing the ball valve.
Abstract:
A fluid switch or valve for an implantable fluid delivery system is provided. The fluid switch or valve includes a fluid chamber having a fluid inlet and a fluid outlet and an internal magnet disposed within the fluid chamber. The internal magnet is moveable such that displacement of the internal magnet restricts the flow of fluid through the fluid chamber.
Abstract:
Beschrieben wird eine Vorrichtung zum Ableiten einer Flüssigkeit, insbesondere Regenwasser, von einer zumindest einen Teil eines Gebäudeumhüllungselementes bildenden ersten Folienlage (4). Ein erstes Ventilelement (26) ist im Bereich einer in der ersten Folienlage (4) vorgesehenen ersten Öffnung (22) derart anordenbar, dass es zwischen einer die erste Öffnung (22) verschließenden ersten Stellung und einer die erste Öffnung (22) zumindest teilweise freigebenden zweiten Stellung verschwenkbar ist. Des Weiteren sind an der ersten Folienlage (4) anbringbare erste Öffnungs- und Schließmittel (30, 32, 34) vorgesehen, die ausgebildet sind, das erste Ventilelement (26) in der ersten Stellung zu halten, solange der das erste Ventilelement (26) beaufschlagende Druck (40a) einer auf die Oberseite der ersten Folienlage (4) gelangten Flüssigkeit (40) kleiner als ein vorbestimmter erster Schwellwert oder höchstens gleich diesem Schwellwert ist, ein Verschwenken des ersten Ventilelements (26) von der ersten Stellung in die zweite Stellung zu ermöglichen, wenn der das erste Ventilelement (26) beaufschlagende Druck (40a) der Flüssigkeit (40) den ersten Schwellwert übersteigt, und das erste Ventilelement (26) von der zweiten Stellung in die erste Stellung zu verschwenken, nachdem der das erste Ventilelement (26) beaufschlagende Druck (40a) der Flüssigkeit (40) im Wesentlichen nicht mehr vorhanden ist.
Abstract:
A system and method for dispensing a predetermined portion of a beverage or drink additive using a cost effective portion control valve that replaces electrical components with mechanical components. The present invention dispenses a controlled portion of a beverage when a lever is activated. A magnetically coupled linkage system can control the exact amount of fluid dispensed. A valve block contains a beverage input, a beverage outlet, and a valve seal.

Abstract:
A magnetically actuated axial valve reduces emissions associated with valve stems while retaining a high flow efficiency. In one embodiment, a valve may have inner and outer magnet rings (22 & 23) which may be permanent magnets (12 & 13). Magnetic actuation utilizing N dFeB rare earth magnets (12 & 13) to maximize available torque in rotating an outer magnet ring 180°, thereby forcing synchronous rotation of an inner magnet ring connected to the valve rotor may be provided. A rotary position sensor may provide reliable indication of open and closed valve positions. A valve incorporating a conical sealing interface between rotating and stationary graphite halves to minimize internal leakage by providing a high degree of self-alignment and amplifying the contact force between the two halves is also provided. Methods corollary to the disclosed apparatus are also provided.
