1. Hydrauliskt reglersystem vid en spindelkross, vid vilken kross huvudaxeln understöds hydrauliskt av en kolv som 5 rör sig i en cylinder, och vilken uppvisar en smörjkrets, till vilket system hör: - en behällare (4) för hydraulvätska, - en pumpenhet (2) och en matningslinje för att leda hydraulvätska frän behällaren tili cylindern, och ίο - en returlinje (8) som leder hydraulvätska frän cylindern tili behällaren, kännetecknat av att systemet uppvisar: - en övertrycksventil (5) som kopplats tili matningslin-jen, samt en förbiledningslinje, som kopplats mellan över- 15 trycksventilen och returlinjen sä att dä trycket i cylindern överstiger öppningstrycket för övertrycksventilen, strömmar vätska frän cylindern via övertrycksventilen tili smörjkret-sen och returlinjen.
2. System i enlighet med patentkrav 1, kännetecknat av att övertrycksventilen (5) har integrerats med krossen eller lämpligen inne i krossen.
3. System i enlighet med patentkrav 2, kännetecknat av att 25 förbiledningslinjen (8) har placerats inne i krossens ram.
4. System i enlighet med nägot av patentkraven 1-3, kännetecknat av att det dessutom innehäller: - en givare (9) som övervakar huvudaxelns höjdläge i 30 krossen, och - en reglerenhet (10) som har kopplats tili givaren och pumpenheten sä att dä cylinderns tryck är lägre än öppningstrycket för övertrycksventilen hälls huvudaxeln automatiskt i ett förutbestämt läge. il : · tftrtMH lii IM '
