Description
458 875 10 15 20 25 30 35 2 automatiskt stannar i samma utgångsläge, alltså en hydraulisk cylinder med "hydrauliskt minne". 458 875 10 15 20 25 30 35 2 automatically stops in the same initial position, ie a hydraulic cylinder with "hydraulic memory".
Detta uppnås genom att urborrningen i andra änden mynnar ut i en oljeport i kloven, inrättad för tillkoppling till den hydrauliska källan och på så sätt, att då förbindelsen mellan den hydrauliska källan och oljeporten i kloven, och förbindelsen mellan den hydrauliska källan och oljeporten i eller vid framgaveln öppnas och för- bindelsen mellan den hydrauliska källan och oljeporten i eller vid bakgaveln stängs, kan kolven drivas fram och tillbaka mellan den fria kolven - som då kommer att ligga an mot bakgaveln och cylinderns framgavel och stoppas på godtyckligt ställe i cylindern och då kolven är stoppad på godtyckligt ställe och förbindelsen mellan den hydrauliska källan och oljeporten i kloven stängs, men förbindelsen mellan den hydrauliska källan och oljeportarna och i eller vid framgaveln och bakgaveln öppnas, kan kolven från sagda utgångsläge alltid drivas helt ut mot fram- gaveln, men inte längre in i cylindern än till sagda utgångsläge, där den fria kolven kommer till anliggning mot cylinderns bakgavel, varvid den hydrauliska cylindern, efter att den från en godtycklig utgångsposition har aktiverats och har gjort ett slag, kan föras tillbaka så att den automatiskt stannar i samma utgàngsposition.This is achieved by the bore at the other end opening into an oil port in the claw, arranged for connection to the hydraulic source and in such a way that when the connection between the hydraulic source and the oil port in the claw, and the connection between the hydraulic source and the oil port in or at the front end is opened and the connection between the hydraulic source and the oil port in or at the rear end is closed, the piston can be driven back and forth between the free piston - which will then abut against the rear end and the front end of the cylinder and be stopped at any point in the cylinder. the piston is stopped at any place and the connection between the hydraulic source and the oil port in the piston is closed, but the connection between the hydraulic source and the oil ports and in or at the front end and rear end is opened, the piston can always be driven completely towards the front end, but no further into the cylinder than to said starting position, where the free piston comes into contact g towards the rear end of the cylinder, whereby the hydraulic cylinder, after it has been activated from an arbitrary starting position and made a stroke, can be returned so that it automatically stays in the same starting position.
Ett utföringsexempel enligt uppfinningen visas på ritningen som delvis i snitt visar en hydraulisk cylinder enligt uppfinningen.An exemplary embodiment according to the invention is shown in the drawing, which partly in section shows a hydraulic cylinder according to the invention.
På ritningen betecknar hänvisningssiffran 1 den hydrauliska cylinderns cylinderrör med framgavel 2, bakgavel 3, kolvstång 4 med kolv 5 och monteringsorgan 6. Dessutom är i cylinderröret 1 anordnat en fri kolv' 7 mellan kolven S och bakgaveln 3, så att det bildas ett utrymme 8 mellan kolven 5 och den fria kolven 7.In the drawing, the reference numeral 1 denotes the cylinder tube of the hydraulic cylinder with front end 2, rear end 3, piston rod 4 with piston 5 and mounting means 6. In addition, a free piston 7 is arranged in the cylinder tube 1 between the piston S and the rear end 3, so that a space 8 is formed. between the piston 5 and the free piston 7.
Utrymmet 8 kan bringas att kommunicera med ett hydraulaggregat (ej visat på ritningen) via en axiell urtagning 9 i kolvstången 4 och en oljeport ll respektive 12.The space 8 can be made to communicate with a hydraulic unit (not shown in the drawing) via an axial recess 9 in the piston rod 4 and an oil port 11 and 12, respectively.
Den hydrauliska cylindern enligt uppfinningen arbetar på följande sätt: När cylinderportarna lÖ och ll ansluts till hydraul- aggregatet, kan kolven 5 drivas fram och tillbaka mellan den fria kolven 7, som då kommer att ligga an mot bakgaveln 3, och lO 15 20 25 30 35 458 875 cylinderns framgavel 2 och kan stannas på godtyckligt ställe.The hydraulic cylinder according to the invention operates in the following way: When the cylinder ports 10 and 11 are connected to the hydraulic unit, the piston 5 can be driven back and forth between the free piston 7, which will then abut against the rear end 3, and 10 15 20 25 30 35 458 875 the front end 2 of the cylinder and can be stopped at any place.
Med kolven 5 stoppad pà godtyckligt ställe i cylindern och förbindelsen mellan oljeport 10 och hydraulaggregatet stängd, men förbindelsen mellan oljeportarna ll, öppen, kan kolven 5 alltid drivas helt ut mot framgaveln 2 från detta utgångsläge, men kolven kan ej drivas längre in i cylindern än till nämnda utgångsläge, kommer att ligga an mot cylinderns bakgavel 3. 12 och hydraulaggregatet där den fria kolven 7 Det är alltså oljemängden i utrymmet 8 mellan kolven S och den fria kolven 7 som bestämmer den s. k. "sammantryckta längden" av den hydrauliska cylindern, medan kolven 5, den fria kolven 7 och mellanliggande större eller mindre oljemängd i utrymmet 8 fungerar som en kolv när förbindelsen mellan oljeportarna 11, 12 och hydraulaggregatet är öppen.With the piston 5 stopped at any place in the cylinder and the connection between the oil port 10 and the hydraulic unit closed, but the connection between the oil ports 11, open, the piston 5 can always be driven completely towards the front end 2 from this starting position, but the piston can not be driven further into the cylinder. to said initial position, will abut against the rear end of the cylinder 3. 12 and the hydraulic assembly where the free piston 7 It is thus the amount of oil in the space 8 between the piston S and the free piston 7 which determines the so-called "compressed length" of the hydraulic cylinder, while the piston 5, the free piston 7 and the intermediate larger or smaller amount of oil in the space 8 function as a piston when the connection between the oil ports 11, 12 and the hydraulic unit is open.
