Abstract

Föreliggande uppfinning avser ett hydraulcylindersystem som innefattarminst två hydraulcylindrar där varje hydraulcylinder innefattar en cylinder med en cylinderbotten och en cylindertopp, en inne i cylindern, mellan botten och toppen axiellt rörligt anordnad kolv som avdelar cylindern i en plussida och en minussida, och anordnad med en central kanal, en kolvstång med en kanal sträckande sig i kolvstångens längdriktning och som med sin ena ände är fastsatt till kolven, en cylindertopp med en öppning med en tätning genom vilken kolvstången sträcker sig, anslutningar för ett flöde av en trycksatt fluid från en hydraulisk pump och hydrauliskt flöde till en tank, där vid användning av hydraulcylindern, kolvstången löper genom cylindertoppen då kolven, genom införsel/bortförsel av fluid i cylindern via anslutningarna kan skjutas fram och tillbaka i cylindern med hjälp av kolvens rörelse och en flödeskanal för tillförsel av fluid till åtminstone en cylinder och/eller bortförsel av fluid från en närliggande cylinder. Den kännetecknas av en manöverventil för styrning av fluiden till/från hydraulcylindersystemet och en riktningsventil vid varje cylinder för styrning av fluiden till/från nästa cylinder, samt ledningar för styrning av riktningsventilerna.The present invention relates to a hydraulic cylinder system comprising at least two hydraulic cylinders, each hydraulic cylinder comprising a cylinder with a cylinder bottom and a cylinder top, a piston axially movably arranged inside the cylinder, between the bottom and the top dividing the cylinder into a plus side and a minus side, and arranged with a central a piston rod with a channel extending in the longitudinal direction of the piston rod and attached at one end to the piston, a cylinder top with an opening with a seal through which the piston rod extends, connections for a flow of a pressurized fluid from a hydraulic pump and hydraulic flow to a tank, where when using the hydraulic cylinder, the piston rod runs through the cylinder top as the piston, by introducing / removing fluid in the cylinder via the connections can be pushed back and forth in the cylinder by means of the piston movement and a flow channel for supplying fluid to at least a cylinder and / or removal of fluid from a nearby cylinder. It is characterized by a control valve for controlling the fluid to / from the hydraulic cylinder system and a directional valve at each cylinder for controlling the fluid to / from the next cylinder, as well as lines for controlling the directional valves.
