Abstract

Szelep folyadékok szabályozásához egy működtető egységgel (4),különösen egy piezoelektromos egységgel, egy szelepházban (7)tengelyirányban eltolható szeleptag (3) mozgatásához, amelyhez egyszeleplezáró tag (12) van hozzárendelve, amely együtthat legalább egyszelepüléssel (19, 15) a szelep (1) nyitásához és zárásához ésszétválaszt egy rendszernyomással rendelkező alacsonynyomású teret(16) egy magasnyomású tértől (17). Ennél a szeleptag (3) legalább egyelső dugattyúval (9) és egy második dugattyúval (11) rendelkezik,amelyek között hidraulikus áttételként dolgozó hidraulikus kamra (13)van kiképezve, ahol a szivárgási veszteségek kiegyenlítéséhez egy amagasnyomású térrel (17) összeköthető töltőberendezés (24) állrendelkezésre. A töltőberendezés (24) legalább egy csatornaszerűüreges térrel (25) van kiképezve, amelyben legalább egy fojtószeleptest (26) úgy van elrendezve, hogy az üreges térben (25), afojtószelep test (26) egyik végén egy a magasnyomású térhez (17)vezető vezeték (33) torkollik be és a fojtószelep test (26) ellenkezővégén egy a hidraulikus kamrához (13) vezető rendszer-nyomás vezetékágazik le. Egy rendszer-nyomás (p_sys) a fojtószelep testben (26) levőfojtószelep furatnak (27) és a dugattyú (9) méreteinek geometriaimeghatározásán keresztül, amely (dugattyú) mentén a rendszernyomás(p_sys) az alacsony-nyomású térig leépül, egy rendelkezésre állónyomás (p_R) függvényében a magasnyomású térben (17) felépül.
