Abstract

A találmány tárgya folyadékvezérlő szelep hozzáfolyó vezetékkel (7) ésszivárgóolaj-vezetékkel (8), amelyek mindig nyomástérrel (6) állnakösszeköttetésben, és dugattyúelemmel (3), amely állítóelemmel (2)állítható át és a hozzáfolyó vezeték (7) és a nyomástér (6) között egyfelső áteresztő nyílást (10) szabaddá tesz, illetve lezár. A találmánylényege, hogy a dugattyúelemnek (3, 4) üléke és tolóeleme (3c) van,amely közvetlenül a dugattyúelem ülékével határosan van elrendezve azelső áteresztő nyílás (10) vezérlésére és tolóelem, (4a) dugattyúelem(4) dugattyúján (4) második szivárgóolaj-vezetékkel összekötöttáteresztőnyílás vezérlésére, aminél a tolóelem (3c) lökethossza (h2)az első áteresztő nyílás (10) nyitásához nagyobb vagy ugyanakkora,mint a második áteresztőnyílás zárására szolgáló tolóelem (4a)lökethossza (h1).
