Imisebenzi echanekileyo, ehlengahlengisiweyo kwiimfuno zeenkqubo ze-hydraulic ezivulekileyo
Le valve yokuzalisa igxile kwiimeko zokusetyenziswa kweenkqubo ze-hydraulic ezivulekileyo. Ifakwe phakathi kwepompo kunye nesixhobo sesibini se-hydraulic esisezantsi (njengevalvu yokulawula i-power steering, isilinda, njl.njl.), kwaye ithatha uxanduva oluphambili lokuzalisa ngobuninzi kwe-accumulator. Umsebenzi wayo ophambili "kukuzalisa xa kuyimfuneko". Ngokweemfuno zenkqubo, ingathabatha ioyile kwipompo yobuninzi ukuze izalise i-accumulator, igqibezele umsebenzi wokuzalisa ngesantya sokuhamba esizinzileyo phantsi koxinzelelo olumiselweyo, kwaye igcine imeko yokuzalisa ingaguquki ngaphakathi koluhlu loxinzelelo olumiselweyo.
Ngexesha lenkqubo yokuzalisa, nangona ukuhamba kwesixhobo se-hydraulic esincedisayo esisezantsi kuya kuncipha, akuyi kuphazamisana kakhulu nokusebenza okuqhelekileyo kwecandelo. Logama nje ivalvu yokuzalisa ingathinteli ukuhamba kunye nokudluliselwa koxinzelelo lwepompo, isixhobo se-hydraulic sesibini esisezantsi sinokuhlala sifumana uxinzelelo olupheleleyo lwenkqubo ukuqinisekisa ukuphuma okuzinzileyo kwamandla enkqubo. Kwangaxeshanye, ukuhamba kokugcwalisa i-accumulator kunye nemida ephezulu nesezantsi yoxinzelelo lwe-accumulator zinokumiselwa njengoko kufuneka kwinkqubo yemveliso, zibonelela ngezisombululo zokuzalisa ezenzelwe wena kwiinkqubo ze-hydraulic phantsi kweemeko ezahlukeneyo zokusebenza.
