Abstract
En bistabil aktuator omfatter et kammer (40) med et fluidinnløp (34) og første og andre fiuidutløp (36, 38), et ventilelement (42) som er bevegelig mellom en første posisjon hvori det samvirker med et første ventilsete for å lukke det første utløp (36) og en andre posisjon hvori det samvirker med et andre ventilsete for å lukke det andre utløp (38), og en elektromagnetisk aktuator (48) opererbar til å drive ventilelementet (42) mellom sin første og andre posisjon, hvori ventilelementet (42) har en første overflate (44) hvorimot fluidtrykket i kammeret (40) virker når ventilelementet (42) er i sin første posisjon for å motstå bevegelse av ventilelement et (42), og en andre overflate (46) hvorimot fluidtrykket i kammeret (40) virker når ventilelementet (42) er i sin andre posisjon for å motstå bevegelse av ventilelementet (42).
