Description
Technical field
The application's case relates to for example, Gao Gong for displacement fluid shifter (liquor pump, gas compressor and synthesizing jet-flow)The long-life actuator of rate.
Background technology
Displacement fluid shifter can provide high fluidity and pressure, but, for example, in order to be suitable for many application (medical treatment dressPut; The heat management of computer, server, LED illumination; And the cooling application of other electronic device), these a little fluids moveDevice must low vibration operate and provide the long-life. In addition, be subject in order to be engaged in space in the situation that not losing fluid propertyIn the product platform of limit, fluid shifter is configured to more and more less size described in these a little application requirements.
If fluid shifter can use the piston of two movements opposite each other, vibration will minimize so, but in order to realizeThis two pistons close, requires the identical Reeb of each piston applications shape. The individually actuating of each piston increased size,Mechanical complexity and cost, and this difficult problem of power of mating on each piston will need control program, this further increasing againPolygamy and cost.
Therefore, there are unsatisfied needs, need to improve fluid shifter activate, make do not lose performance andIn the situation in life-span, the integrated of fluid shifter assembly can be realized reduced size, provide simultaneously straightforward procedure with guarantee byIdentical Reeb shape is applied to each piston.
Summary of the invention
In order to meet these needs and to overcome the limitation of on going result, the application's case discloses to have and is arranged between armatureDouble armature/the diaphragm actuators of fixed coil, wherein, in order to make minimum vibration, is applied directly to institute by produced magnetic forceState between two pistons, thereby guarantee that these two pistons stand identical instantaneous actuation force. In order further to meet this little needThe limitation of wanting and overcome on going result, the integrated piston of method of actuating and actuator are with defeated for given pumping powerGo out to reduce the size of fluid shifter, eliminate and can cause that any dynamic electric pneumatic module of fault and the lost of life (for example shakes simultaneouslyMoving-wire).

Detailed description of the invention
Fig. 1 embodiment according to the present invention embodiment illustrates some key function concept of fluid actuator, wherein fixingCoil 6 is positioned at between a pair of armature 2 and 4. In the time of described coil electricity, in armature 2 and 4 interior generation magnetic fields,And the gained magnetic flux loop path of described is illustrated by illustrated in dashed lines in Fig. 2. Described magnetic field is between described armatureAir gap in form gravitation, described gravitation pulls two armatures close to the other side. Described power is applied directly to described twoBetween armature, guarantee the transient force that armature 2 and 4 stands and therefore Reeb shape is always identical.
How Fig. 3 illustrates the actuator of Fig. 1 for fluid displacement apparatus. Armature 16 and 18 is attached to accordinglyBarrier film 8 and 10. Each has barrier film 8 and 10 and makes described barrier film can carry out the annular cantilever bullet of larger axis to displacementSpring matrix. In practice, barrier film 8 and 10 will have elastomer overmold (not showing) so that wiper seal to be provided. EveryThe one that film 8 and 10 represents in available many kinds of barrier films within the scope of the invention, still utilizes actuating wherein simultaneouslyPrinciple. Described barrier film can be configured as (for instance) is as in PCT/US2011/022386 international applicationShow, described application case is incorporated herein by reference in full. Barrier film 8 and 10 and shell 12 mineralization pressuresSealing. Discharge chambe 20 by barrier film 8 and 10 and shell 12 delimit. In the time of coil electricity, magnetic force causes armature 16 and 18Move to the other side along its corresponding barrier film 8 and 10, thereby the volume of fluid chamber 20 is reduced. Described in turn-offingWhen coil, the potential energy being stored in barrier film spring returns to promotion armature and barrier film in the opposite direction, thereby makes fluid chamber20 volume increases. The gained circulation volume being associated with connection and the cut-out of coil reduces and increases will fluid chamberFluid in 20 applies energy, thereby application-specific (for example, pumping liquid and gas or penetrate for synthetic is for instance providedStream provides power or other fluid to move application (for example, mix, measure or sample etc.)) needed fluid energy.
The vibration of armature 16 and 18 causes that reaction force is transferred to shell 12 via respective diaphragm 8 and 10. At armature 16And in the degree that 18 quality equates and the spring rate of barrier film 8 and 10 is equal, if the displacement of armature 16 and 18Equate, will eliminate so reaction force, thereby cause MIN shell vibration. By sending identical to each armaturePower amplitude and Reeb shape, as fluid movement actuator disclosed herein can operate, each armature will be carried out identicalDisplacement amplitude and displacement waveform, thereby realize zero or MIN shell vibrate desired condition.
The fluid shifter of Fig. 3 can the operation of its mechanical mass spring resonant frequency, wherein said resonant frequency by barrier film andThe quality through cluster spring rigidity and fluid and armature of fluid determines.
The fluid shifter of Fig. 3 is shown in Fig. 4 with different sectional views, to show how coil can be installed securelyTo shell 12. In order to show described mounting arrangements, in Fig. 4, show the only one in barrier film now. Coil 14 is by lineCircle clip 22 and 24 fixings, these coil clips sandwich again in shell 12. The design of this fixed coil eliminated forThe dynamically needs of the moving electric power wire of coil and also eliminated the incipient fault of these a little wires or lead-in wire, thus improve the life-spanAnd reliability.
Move application for any one above-mentioned fluid, the both sides of barrier film all can be used for the work of flowing. For instance, figure5 show extra end plate 26 and 28, and described end plate forms corresponding fluid chamber 30 and 32. For appointing in above-mentioned applicationOne, fluid chamber 30 and 32 can be used for to fluid transferring energy.

As figureIn 6, show, the armature 40 and 42 of opposition is attached to corresponding barrier film 34 and 36, and described barrier film is attached to again shell38. Fixed coil 44 is installed to shell 38 securely by coil arm 46 and 48. In the design of Fig. 6, withIn Fig. 3 and 4 show design compare, described coil more fully by armature material around, wherein coil sections is at electricityOutside pivot material. The part outside armature material of coil produces less magnetic field in armature, and this has reduced actuatorEfficiency. Further variant can comprise the power of being used to form (voice coil type of for example permanent magnet and moving magnet fixed coilActuator) replacement assemblies, wherein said armature will replace with voice coil type magnet and support that magnet has permanent magnetism to provideThe coil air gap of field.
