A valve for exhaust gas recycling in an IC engine has a valve element (16) with a corrugated metal bellows (40) fitted on the input side and linked to the output side by gas ducts (22) through the valve element. The bellows seals the gas valve from leaks and is fitted between the valve element and the gas duct. The design effectively equalises the gas pressures across the valve and allows a simpler valve control. |
