1. En för en hydraulisk hiss avsedd styrventil genom vilken tryckmediets huvudflöde (4, 5) flödar, och i vilken styrven- 5 til f inns en hastighetsdorn (2), som rör sig med tryckme-diets flöde och vars position bestämmer tryckmediets flöde tili hissens arbetscylinder, och ett tili hastighetsdornens vardera ändor förenat, för tryckmediet avsett kanalsystem (1) som är förenat med huvudflödes kanalsystemet och i 10 vilket tryckmediet flödar, varvid det frän hastighetsdornens första ända utgär ett flöde och till dess andra ända kommer ett flöde via en drossel (9), kännetecknad av, att tili tryckmediets kanalsystem (1) har förutom drosseln (9) kopp-lats en med flödesmotständskomponent (12-15) försedd til-15 läggskanal (10) sälunda att tilläggskanalens (10) första ända (10a) är i förbindelse med en sädan del av tryckmediets kanalsystem (1), där trycket (p0) är det samma som i hastighetsdornens (2) första ända (2a) , och att tilläggskanalens andra ända (10b) är i förbindelse med en sädan del 20 av tryckmediets kanalsystem (1) , där trycket (ρχ) är det samma som i hastighetsdornens (2) andra ända (2b).
2. En styrventil enligt patentkrav 1, kännetecknad av, att flödesmotständskomponenten innefattar en kapillärdrossel 25 (12), en cylinder (13), en där innuti rörlig hjälpkolv (14) samt en mellan hjälpkolven och cylindern ansluten, i hjälp-kolvens rörelseriktning verkande fjäder (15), och att kapil-lärdrosseln (12) är kopplad i serie med cylinder-, hjälpkolv-, fjäderkombinationen (13-15).
