Project SummaryA “control interlock” to stop air entering a dairy milking vacuum system. When milking cows, a pulsation unit lets atmospheric air into chambers at the milking claw which makes a gripping motion and then milk flows from the cow. When milk stops flowing, existing controls detach the...
