(54)	A conduit system for the exhaust gases in a multi combustion engine system and a damper for it

(57) The invention relates to a conduit system for the exhaust gases in a multi combustion engine system, in which conduit system the exhaust gas conduits (11) of two or more combustion engine systems (10) are attached onto a common head conduit (13), and each exhaust gas conduit (11) includes a damper (14) which also functions as an overpressure guard in order to protect the system from a sudden pressure shock. The axle (15) of the damper (14) is arranged eccentrically in relation to the blade (17) and is set to open due to overpressure.
