Abstract

A találmány tárgya hidraulikus szabályozási kör gépjármű felfüggesztőrendszeréhez. A gépjármű felfüggesztő rendszere tartalmaz egyszivattyút (34), két felfüggesztő hengert (12, 14) és egy szabályozásikört, amely szabályozza a felfüggesztő hengerek (12, 14) nyomás aláhelyezését. Mindkét felfüggesztő hengernek (12, 14) van egy fejvége ésegy rúdvége. A szabályozási kör tartalmaz egy rúdnyomás-szabályozóarányos szelepet (36), amelynek van egy első nyomásbemenete (42) ésegy második nyomásbemenete (48). Az első nyomásbemenetre (42) afelfüggesztő henger (12, 14) fejvégével összeköttetésben lévő nyomáshat, a második nyomásbemenetre (48) a felfüggesztő henger (12, 14)rúdvégével összeköttetésben lévő nyomás hat. A rúdnyomás-szabályozóarányos szelep (36) a nyomást a felfüggesztő henger (12, 14)rúdvégében a felfüggesztő henger (12, 14) fejvégében fennálló nyomásfüggvényében, és ezzel a nyomással arányosan szabályozza. Egyfelfüggesztő csillapító szelep (28) szabályozza az összeköttetést afelfüggesztő henger (12) egy kamrája és egy akkumulátor (26) között. Ó
