Abstract

Oppfinnelsen angår en ventilstyring for en gassvekslingsventil i en forbrenningsmotor med minst et fjærelement (44, 46) for forspenningen av ventilen (12) i en endestilling, og en fikseringsinnretning (38) for løsbar fiksering av ventilen (12), hvor fjærelementet (44, 46) for forspenningen av ventilen (12) støtter seg i en bevegelig innsats (34) som ved hjelp av en innstillingsinnretning (36) i innstillingsretningen for ventilen (12) mellom en ventiltallerken og en ventiltallerkenfjærs endeposisjon kan omstilles til innstilling av en forspenning som virker inn på ventilen (12) gjennom fjærelementet (44, 46).
