Claims (6)

1. Hydraulisk trevägsventil med öppet centrum, speciellt för en elektrisk strömbrytares hydrauliska kontrollkrets, där en rörlig kontakt drives med en differentialventil, vilken trevägsventil omfattar ett sugventilhuvud (40) och ett tömnings-ventilhuvud (44), vilka är fysiskt ätskilda men som päverkar varandra i sin skjutrörelse, varvid nämnda sugventilhuvud tvingas mot stängningsläge genom en fjäder (48) och nämnda tömningsventilhuvud drives mot stängningsläge genom att försätta en hydraulisk pilotventil (49,50) under tryck, kännetecknad därav, att nämnda ventil har en andra fjäder (58), som päverkar tömningsventilhuvudet (44) för att tvinga nämnda ventilhuvud tili stängningsläge, att nämnda andra fjäder (58) är kraftigare än den första fjädern och att tömningsventilhuvudet (44) försetts med en elastisk halvläsnings-mekanism (62,64,66) med begränsad läsningsverkan, som anpassats att hälla tömningsventilhuvudet i öppet läge mot den andra fjädern (58) rörelse, medan pilotventilen (49,50) är utan hyd-rauliskt tryck, och som anordnats att frisätta nämnda ventilhuvud i sitt stängningsläge, dä nämnda ventilhuvud underkastas päverkan av säväl den nämnda andra f jädern (58) som den tryck-' ‘ belagda pilotventilen.
‘ 2. Ventil enligt patentkravet 1, kännetecknad därav, att halvläsningsmekanismen försetts med en utskjutande sluttande del (62) pä en förbindingstapp (61), vilken tapps funktion är att förena tömningsventilhuvudet (44) med pilotven-tilens (49,50) kolv (49), och halvläsningsmekanismen försetts med minst en elastisk skjutenhet (64,66) uppstödd av nämnda ventils stomme (36), och som anordnats att samverka med nämnda sluttande del (62).
3. Ventil enligt patentkravet 2, kännetecknad därav, att den nämnda skjutenheten omfattar minst en kula (64), 16 85535 som av en fjäder (66) tvingas mot tömningsventilhuvudets (44) förbindningstapp (61).
4. Ventil enligt patentkravet l, kännetecknad därav, att tömningsventilhuvudet (44) har ett längre rörelseom-räde an sugventilhuvudet (40).
5. Ventil enligt patentkravet 4, kännetecknad därav, att tömningsventilhuvudet (44) utövar en skjutkraft pä sugventilhuvudet (40) med tillhjälp av en skjuttapp (54), som är stelt förbunden med det ena av ventilhuvudena (44) och att skjuttappens ytterända ligger pä ett avständ (68) frän det andra ventilhuvudet (40) i ventilens tömningsläge.
6. Ventil enligt patentkravet l, kännetecknad därav, att den självupprätthällande kretsen (70-72) placerats i ventilstommen (36). « · • · • · • · * · *
