摘要： A connection device for connecting two turbine housings (1, 2) of a two- stage turbocharging system includes a male/female joint for joining the two turbine housings; a cylindrical ring seal (3) installed under compression inside the male/female joint for sealing exhaust gas; and a vibration damper (4) in a shape of a flat washer and placed between the two housings. The cylindrical ring seal can be made of stainless steel mesh impregnated with vermiculite or graphite. The vibration damper can be made of stainless steel mesh but not impregnated.
