Claims (5)
1. Tvävägs-strömningsregleringsventil innefattande en hyd-raulisk kompensator (12), som ligger axiellt förskjutbart i husets (6) cylindriska häl för att reglera strömningen genom en axiell inloppsöppning (8) och en eller flera tvärgäende utloppsöppningar (10), en tryckkammare (14) med en i förbin-delse med kompensatorn (12) stäende f jäder (16) , en regie-ringsventil för regiering av trycket inom tryckkammaren (14) och sä för regiering av kompensatorns ställning, strömnings-givarorgan för avkänning av genomströmningsmängden genom in-loppsöppningen (8), varvid genomströmningsgivarorganen kan axiellt förskjutas i förhällande tili kompensatorn, och en förskjutningsgivare för avkänning av strömningsgivarorganens ställning och för styrning av regleringsventilen beroende pä strömningsgivarens ställning, kännetecknad av att kompensatorn (12) uppvisar ett axiellt genomgäende häl och det sträcker sig över tryckkammaren (14) och axiellt begränsar tryckkammaren vid dess bägge ändor och att strömningsgi-varorganen innefattar en axiellt förskjutbar kolv (20), som leds i kompensatorns axiella häl.
2. Tvävägs-strömningsregleringsventil enligt patentkravet 1, kännetecknad av att strömningsgivarorganen vidare innefattar en fjäder (26), som verkar i riktning av öppningen ·; (8) .
3. Tvävägs-strömningsregleringsventil enligt patentkravet 1, kännetecknad av att koiven (20) uppvisar minst ett genomgäende häl (28, 30) för att den skall vara i hydrostatisk j ämvikt.
4. Tvävägs-strömningsregleringsventil enligt patentkravet 1, kännetecknad av att inloppsöppningen (8) utbreds koniskt i strömningsriktningen och fungerar tillsammans med koiven (20) för att bilda en ringformig strömningsspalt, vars bredd bestäms enligt genomströmningsmängden genom att förskjuta strömningsgivaren (20) axiellt.
