Komora logicznego ele¬ mentu plynowego wyposazona jest w przestrzenny uklad otworów strumienia glównego, wejsciowych i wyjsciowych, przy czym os co najmniej jednego otworu wejsciowego jest prostopadla do osi stru¬ mienia glównego, a sama jest przecinana przez osie innych otworów wejsciowych. Otwór wejsciowy strumienia glównego jest wspólosiowy z otworem wyjsciowym. Wewnatrz komory logicznego elemen¬ tu plynowego umieszczone sa ekrany eliminujace powstawanie wirów. W przewodach doprowadza¬ jacych plyn do logicznego elementu plynowego umieszczone sa opory pneumatyczne lub hydra¬ uliczne.Niedogodnoscia logicznego elementu plynowego jest jego wrazliwosc na zaklócenia zewnetrzne, spowodowana tym, ze uklad strumieni tego elemen¬ tu znajduje sie w komorze otwartej oraz tym, ze 10 15 20 25 30 strumienie elementu biegna w przestrzeni otwar¬ tej. Przestrzenny uklad otworów elementu *powo¬ duje trudnosci technologiczne oraz trudnosc osio¬ wego ustawienia otworów, a takze trudnosc wyeli¬ minowania wichrowatosci osi otworów, które po¬ winny sie przecinac. Ponadto przestrzenny uklad otworów wymaga stosowania ekranów eliminuja¬ cych powstawanie wirów o skomplikowanym ksztalcie, których ustawienie w komorze nastrecza duze trudnosci.Inna niedogodnoscia logicznego elementu plyno¬ wego jest koniecznosc doprowadzenia plynu do wejsciowych otworów strumieni glównych przewo¬ dami bez zalaman, w celu ustabilizowania strumie¬ ni glównych. • Celem niniejszego wynalazku jest zbudowanie lo¬ gicznego elementu plynowego o prostej technologii, odpornego na zaklócenia zewnetrzne i niewrazli¬ wego na sposób doprowadzenia plynu do wejscio¬ wego otworu strumienia glównego.Cel wynalazku zostal osiagniety przez zbudowa¬ nie strumieniowego elementu logicznego o kaskar dowym ukladzie strumieni w jednej otwartej ko¬ morze wyposazonej w co najmniej jeden otwór wejsciowy strumienia glównego i co najmniej je¬ den otwór wyjsciowy oraz co najmniej dwa otwo¬ ry wejsciowe strumieni sterujacych, którego komo¬ ra ograniczona jest dwiema równoleglymi plasz¬ czyznami, a wszystkie otwory wejsciowe i wyjscio¬ wy umieszczone sa przy jednej z tych plaszczyzn, 62 36462 364 3 4 mieniami sterujacymi sygnal wyjsciowy ma war¬ tosc „0".

Strumienie sterujace 5 wyplywajace z otworów wejsciowych 4 i 6 moga oddzialywac kaskadowo na strumien glówny przez oddzialywanie na strumien sterujacy wyplywajacy z otworu wejsciowego 8. Analogicznie oddzialywu- ja strumienie sterujace wyplywajace z tftworów io wejsciowych 17 i 19. Ekrany 13 i 14 pelnia znana role w logicznych elementach turbulentnych.Dzieki temu, ze wszystkie strumienie elementu biegna przy jednej plaszczyznie P komory oddzia¬ lywania strumieni oraz ze komora ta ograniczona 15 jest dwiema równoleglymi plaszczyznami, znacznie wzrosla odpornosc elementu na zaklócenia ze¬ wnetrzne. Usytuowanie wszystkich otworów wej¬ sciowych i wyjsciowych elementu przy jednej pla¬ szczyznie powoduje, ze osiowe ustawienie odpo- 20 wiednich otworów jest znacznie latwiejsze niz w przypadku przestrzennego ukladu otworów, jak równiez eliminuje mozliwosc wichrowatosci otwo¬ rów, które winny sie przecinac.W logicznym elemencie plynowym wedlug paten... 25 tu 58367 przeplyw wszystkich strumieni przy jed¬ nej plaszczyznie byl niemozliwy, poniewaz przy otworze wyjsciowym powstawalo szkodliwe spie¬ trzenie plynu, uniemozliwiajace prace takiego ele¬ mentu.

The logic fluid element known from patent No. 58367 has a cascade arrangement of jets in one open chamber equipped with at least one the main stream inlet and at least one outlet and at least two control stream inlets, all of the input and output signals being two-state. The logical fluid element chamber is provided with a three-dimensional arrangement of the main, inlet and outlet openings, the axis of at least one inlet port being perpendicular to the axis of the main stream and itself being intersected by the axes of other inlet ports. The main stream inlet is coaxial with the outlet. Vortex suppression screens are provided within the logical fluid element chamber. Pneumatic or hydraulic resistances are located in the lines carrying the fluid to the logic fluid element. The disadvantage of the fluid logic is its sensitivity to external disturbances, due to the fact that the flow pattern of this element is in an open chamber and that The jets of the element run in the open space. The spatial arrangement of the holes of the element causes technological difficulties and the difficulty of aligning the holes axially, as well as the difficulty of eliminating the twisting of the axes of the holes that should intersect. In addition, the spatial arrangement of the holes requires the use of screens that eliminate the formation of complex-shaped vortices, which are difficult to position in the chamber. Another disadvantage of the logic fluid element is the need to bring the fluid to the entry holes of the main streams through conduits without damper to stabilize the streams ¬ n and major. The object of the present invention is to build a logic fluid element with a simple technology, resistant to external disturbances and insensitive to the way of fluid feeding into the main stream input orifice. The object of the invention was achieved by building a stream logic element with a cascade arrangement streams in one open chamber equipped with at least one main stream inlet and at least one outlet and at least two control stream inlets, the chamber of which is bounded by two parallel planes and all openings Input and output are located at one of these planes, 62 36462 364 3 4 with the control voltage, the output signal has the value "0". Directly on the main stream, the control streams flowing from the inlets 8 and 16 can act. Control streams 5 from input 4 and 6 can cascade the head stream by influencing the control stream flowing from the input port 8. The control streams from the tfs and input 17 and 19 have a similar effect. Screens 13 and 14 play a known role in logical turbulent elements. P of the jet interaction chamber and the fact that this chamber 15 is bounded by two parallel planes, the resistance of the element to external disturbances is significantly increased. The location of all the input and output holes of the element on one plane makes the axial alignment of the corresponding holes much easier than in the case of a spatial arrangement of holes, and also eliminates the possibility of twisting of the holes that should intersect. According to patents 58367, the flow of all the streams at one plane was impossible because a damaging build-up of the fluid was created at the exit opening, preventing the operation of such an element. These inconveniences have been eliminated in the elements built according to the present. of the invention by the implementation of the discharge channel 21 at the outlet opening. A further increase in the resistance of the element to external disturbances was achieved in building elements according to the present invention due to the placement of protective walls 9 and 10 directly along the main stream path. According to patent 58367, their high sensitivity to the way in which the fluid enters the main stream inlet port has been removed by placing a curved, most preferably, halfway along the feed channel upstream of the port. An advantage of the invention is also that the flux logic elements constructed according to the invention consist of two flat plates, which enables the use of a simple technology for the production of individual boards and their assembly. 50 PL PL
