Description

Foreliggende oppfinnelse angår en strømningsinnretning. The present invention relates to a flow device.

Oppfinnelsen gjelder en anordning for styring av en fluid-strømning og som omfatter et kanålsystem med en stiv inn-løpskanal i forbindelse med et hulrom samt minst to utløps-kanaler ut fra hulrommet; idet anordningens særtrekk i henhold til oppfinnelsen består i at minst to bøyelige.membraner danner hvert sitt veggavsnitt av hulrommet/og hvert sådant veggavsnitt strekker seg mellom .inngangsåpningen til en av nevnte utløpskanaler og innløpskanalens munning, idet det hele er anordnet slik at et hvilket som helst av.membranene ved hjelp av et.trykkmedium kan bringes til utbøyning i konveks form innover i hulrommet, således at strømnings-tverrsnittet av inngangsåpningen til den tilstøtende utløps-kanal reduseres, for ved hjelp av Coanda-effekten å bringe fluidstrømningen'til å forandre sin retning fra å forløpe gjennom utløpet.lengst bort fra !det utbøyde membran til å forløpe gjennom utløpet nærmest ;det utbøyde membran. The invention relates to a device for controlling a fluid flow and which comprises a channel system with a rigid inlet channel in connection with a cavity and at least two outlet channels out of the cavity; as the special feature of the device according to the invention is that at least two flexible membranes each form its own wall section of the cavity/and each such wall section extends between the entrance opening of one of said outlet channels and the mouth of the inlet channel, the whole being arranged so that a preferably by means of a pressure medium, the membranes can be caused to bend in a convex shape inwards into the cavity, so that the flow cross-section of the entrance opening to the adjacent outlet channel is reduced, in order to cause the fluid flow to change by means of the Coanda effect its direction from passing through the outlet furthest away from the deflected membrane to passing through the outlet closest to the deflected membrane.

Oppfinnelsens anordning vil nå bli nærmere beskrevet ved hjelp av et utførelseseksempel og under henvisning til den vedføyde tegning, hvorpå:' The device of the invention will now be described in more detail by means of an embodiment and with reference to the attached drawing, whereupon:

Fig. 1-3 viser skjematisk lengdesnitt gjennom en anordningFig. 1-3 shows a schematic longitudinal section through a device

i henhold til oppfinnelsen i tre* >f oirsk jellige arbeidssituasjoner. in accordance with the invention in three* >f oirish working situations.

På tecningen viser fig. 1 - 3 en ■ anordning 1 for styring åv en fluidstrømning, idet denne anordning omfatter■et kanal-system med en stiv innløpskanal 3 i forbindelse med et hulrom 2 samt to utløpskanaler 4, 5 som•fører ut fra hulrommet. Dette kanålsystem omfatter også bøyelige•membraninnretninger 8, 8', som.ved hjelp av ytre trykk fra et trykkmedium i tfykk-kammeret 7, 7' kan deformeres til å påvirke nevnte fluid-strømning-. Membranene 8, 8 \ strekker seg mellom innløps-åpningen til hver sin tilordnedejutløpskanal og munningen av innløpskanalen 3, idet nevnte membraner utgjør hvert sitt The drawing shows fig. 1 - 3 a device 1 for controlling a fluid flow, this device comprising a channel system with a rigid inlet channel 3 in connection with a cavity 2 and two outlet channels 4, 5 which lead out from the cavity. This cannula system also comprises flexible membrane devices 8, 8', which, with the help of external pressure from a pressure medium in the compression chamber 7, 7', can be deformed to affect said fluid flow. The membranes 8, 8 extend between the inlet opening of each assigned outlet channel and the mouth of the inlet channel 3, said membranes each constituting

"veggavsnitt av hulrommet 2. Hvert ay membranene 8,- 81 kan bøyes til konveks form innover, i hulrommet, hvorved tverr-snittet av innløpsåpningen til den tilstøtende utløpskanål kan reduseres i sådan grad at fluidstrømningen ved hjelp av Coanda-effekten bringes til å forandre sin retning, fra for eksempel utløpskanalen 4 til utløpskanålen 5 som ligger nærmest nevnte utbøyde membran 8' (se fig. 2 og 3), eller vice versa i det tilfelle membranet 8 utbøyes. "wall section of the cavity 2. Each ay the membranes 8, - 81 can be bent to a convex shape inwards, in the cavity, whereby the cross-section of the inlet opening of the adjacent outlet cannula can be reduced to such an extent that the fluid flow is caused to change by means of the Coanda effect its direction, from, for example, the outlet channel 4 to the outlet channel 5 which is closest to said bent membrane 8' (see fig. 2 and 3), or vice versa in the event that the membrane 8 is bent.

Fortrinnsvis består anordningen x henhold til oppfinnelsenPreferably, the device x according to the invention consists

i det minste delvis av gummi eller et annet ettergivende eller bøyelig, material.. at least partially made of rubber or another compliant or flexible material..

Videre omfatter oppfinnelsens anordning fortrinnsvis en skulderflate omkring munningen av innløpskanalen 3 i hulrommet 4, for derved å øke virkningen av Coarida-effekten. Furthermore, the device of the invention preferably comprises a shoulder surface around the mouth of the inlet channel 3 in the cavity 4, thereby increasing the effect of the Coarida effect.
