Description

Vynález sa týká diferenoiálneho tsleakopiokého potrubia pre hydraulické obvody.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to differential-pressure piping for hydraulic circuits.

Óčelom vynálezu je umožnit přepojenie prvkov hydraulického systému konajúeich voči sebe vzájemný pohyb tam, kde sa nedajú použit pryžové hydraulické hadice, či už je to v dosledku velkých pronášených výkenov, odolnosti vožl agresívneau prostredlu, životnosti, možnosti mechanického požkodeala, sérekov na prieatorové rozmiestaenle, avýšenie bezpečnosti a pod.The purpose of the invention is to enable the interconnection of hydraulic system elements acting relative to one another where rubber hydraulic hoses cannot be used, whether due to large penetrated boards, resistance to aggressive environments, durability, mechanical damage potential, serums to preator placement, security and the like.

Doteraz znány systém používá k prepejeaiu prvkov hydraulického obvodu trubkové otočné kíby. RozliSuje v podstatě dva základné typy klbov: trubkový otočný kíb s klzným či valivým uložením s možnoatou nateč«ala v jednej rovině a trubkový otočný kíb s gulovým uložením a možnoatou obeoného natečením do určitého dovolaného uhla. RÍby sú navzájom propojené potrubia. K propojeniu dvooh prvkov hydraulického obvodu, koaajúeioh obecný pohyb bolo třeba použit potrubia s minimálně třemi trubkovými otočnými kíbmi.The prior art system uses tubular swivels to transfer the hydraulic circuit elements. It distinguishes essentially two basic types of joints: a tubular swivel joint with a plain bearing and a rotatable ball bearing in one plane and a tubular swivel joint with a ball bearing and possibly a circular swivel to a certain angle. The fish are interconnected by piping. Pipes with at least three tubular swivel joints had to be used to interconnect the two pairs of hydraulic circuit elements, the general movement.

Použitie tohoto systému pri spojení takých, prvkov hydraulického obvodu, ktoré konali voči sebe pohyb po jednej priaako, alebo prlaakáoh rovaebežuýeh, · nodostatkom volného priestoru mimo spojnice týchto prvkov, bolo konitrukčae velmi obtiažne rležitelné. Spojní cou rozoaieae úsečku preloženú oez spojované mieeta prvkov hydraulického obvodu. Musel sa použit velký počet trubkových otočných klbov a nosným systémem, připadne sa spojenie aodalo prevlest vSbec.The use of this system in joining such hydraulic circuit elements which have moved against each other in a single movement, or in such a way that there is a lack of free space outside the connection lines of these elements, has been very difficult to design. Connecting cou rozoaieae line segment folded off from the joint sweeps elements of the hydraulic circuit. A large number of tubular articulated joints and a support system had to be used, and the connection eventually passed through at all.
