Description

457 520 När signaler via de båda ledningarna 1 och 2 når ELLER- elementet 3, utväljer detta element allt efter behov den snabbaste eller den största signalen och matar denna via ledningen 4 till reläet 5. Reläet 5 utnyttjas för mängdförstärkning. Det hade tidigare stängt av förrådsledningen 6 och anslutit arbetsledningen till ett avlastningsställe. Reläet kopplar nu om och förbinder för- rådsledningen 6 med arbetsledningen 8, samtidigt som avlastnings- stället avstänges. Arbetscylindern 9 beskickas på kortaste väg med luft från förrådsbehâllaren 7. 457 520 When signals via the two lines 1 and 2 reach the OR element 3, this element selects the fastest or largest signal as required and feeds it via the line 4 to the relay 5. The relay 5 is used for quantity amplification. It had previously closed the storage line 6 and connected the work line to a unloading point. The relay now switches and connects the supply line 6 to the work line 8, at the same time as the unloading point is switched off. The working cylinder 9 is loaded in the shortest way with air from the storage tank 7.

På detta sätt manövreras arbetscylindern 9 snabbt och säkert.In this way, the working cylinder 9 is operated quickly and safely.

Styrningen via ledningarna 1 och/eller 2 kan genomföras hydrau- liskt, pneumatiskt eller elektriskt.The control via lines 1 and / or 2 can be carried out hydraulically, pneumatically or electrically.

Fig. 2 visar en konstruktion vid vilken ett av två reläelement 11 12 bestående relä 11/12 är anordnat i ett ELLER-kopplingsor- gan 10. Organen 10, 13. och 11 och 12 utgör delar av en mämgdförstärkare När signaler via de båda ledningarna 1 och 2 når till mängdför- stärkaren 13, är de båda reläelementen 11 och 12 valbara medelst ELLER-anknytningen och endast den snabbare eller kraftigare ge- nomförda förstärkningen når via arbetsledningen 8 till arbetscy- lindern 9.Fig. 2 shows a construction in which a relay 11/12 consisting of two relay elements 11 12 is arranged in an OR coupling member 10. The means 10, 13 and 11 and 12 form parts of a multi-amplifier When signals via the two lines 1 and 2 reach the quantity amplifier 13, the two relay elements 11 and 12 are selectable by means of the OR connection and only the faster or more powerful amplification reaches via the working line 8 to the working cylinder 9.

Fig. 3 visar en variant vid vilken två reläelement 14 och 15 är anordnade framför ELLER-organet 16, vilket via tvâ ledningar 17 och 18 matas från mängdförstärkaren.Fig. 3 shows a variant in which two relay elements 14 and 15 are arranged in front of the OR means 16, which is fed via two lines 17 and 18 from the quantity amplifier.

När de båda ledningarna 1 och 2 avger signaler, omkopplas relä- elemanæm 14 och 15 och under matning från förrådsbehållaren 7 strömmar två mängdflöden via ledningarna 17 och 18 till ELLER- -organet 16. Detta väljer den snabbare eller kraftigare mängd- strömmen och låter denna via arbetsledningen 8 nå arbetscylindern 9.When the two lines 1 and 2 emit signals, relay elements 14 and 15 are switched and during supply from the storage tank 7, two quantity flows flow via the lines 17 and 18 to the OR means 16. This selects the faster or stronger quantity current and allows this via the work line 8 reach the working cylinder 9.

Fig. 4 visar en något annorlunda konstruktion. Här utnyttjas en tvâkrets arbetscylinder 20 med integrerad ELLER-funktion. Såsom 3 457 520 vid utföringsexemplet enligt fig. 3 användes även här två relä- element 14 och 15, som beskickar ledningarna 17 och 18 med flö- den. De båda flödena tillföres den tväkretsiga arbetscylindern 20, som med sitt integrerade ELLER-element väljer det för ögon- blicket högre eller snabbare kommande trycket resp. en motsvaran- de signal och med detta påverkar arbetscylindern.Fig. 4 shows a slightly different construction. Here, a two-circuit working cylinder 20 with integrated OR function is used. As in the embodiment according to Fig. 3, two relay elements 14 and 15 are used here, which charge the lines 17 and 18 with currents. The two flows are supplied to the cross-circuit working cylinder 20, which with its integrated OR element selects the moment of higher or faster coming pressure resp. a corresponding signal and thus affects the working cylinder.

Fig. 5 slutligen visar att det vid en arbetscylinderkonstruktion av den i fig. 4 visade typen även är möjligt att med en genom led- ningen 2 styrd krets direkt beskicka arbetscylindern 20 med en signal och endast förse en av kretsarna, således den andra, med förstärkning via ett relä 23. Även vid en sådan konstruktion tillföres de båda flödena till ar- betscylindern 20, som med sitt integrerade ELLER-element väljer det för ögonblicket högre eller snabbare ankommande trycket eller en motsvarande signal och med detta påverkar arbetscylindern.Fig. 5 finally shows that in a working cylinder construction of the type shown in Fig. 4 it is also possible with a circuit controlled by the line 2 to directly charge the working cylinder 20 with a signal and supply only one of the circuits, thus the other, with reinforcement via a relay 23. Even with such a construction, the two flows are supplied to the working cylinder 20, which with its integrated OR element selects the currently higher or faster arriving pressure or a corresponding signal and thus influences the working cylinder.
