Abstract

Inventia se refera la un ventil de suprapresiune pentru elemente hidraulice ale sustinerilor miniere de diferite sarcini. Ventilul prevede ca, coaxial cu pistonul, sa fie amplasat un manson în forma de teava, care, longitudinal, este strabatut de cel putin un canal legat permanent la sursa hidraulica de presiune mare, legatura radiala fiind realizata între o suprafata a pistonului si o suprafata a mansonului. într-o prima treapta de evacuare, circulatia radiala a fluidului este realizata printr-un interstitiu dintre suprafata exterioara si a pistonului si cel putin o suprafata ce o înconjoara si un canal de evacuare, iar în a doua treapta de evacuare, circulatia radiala este realizata prin lichidul condus printr-o marire a sectiunii de curgere la canalul de evacuare.
