Abstract

The present invention relates to an exhaust valve assembly (18) for a large two-stroke diesel engine (1). The assembly (18) includes an exhaust valve (11) that is movable in opposite directions between a closed position and a open position. A double acting spring assembly (40) is operably connected to the exhaust valve (11) and forms a mass-spring system together with the exhaust valve (11) and the mass of any other parts moving in unison with the exhaust valve (11). The double acting spring assembly (40) stores energy during translation of the exhaust valve (11) back and forth between the closed and open position for subsequent propulsion of the exhaust valve (11) in an opposite direction. Hydraulic means (50) hold the exhaust valve (11) on command from a controller (27) in the closed or in the open position.
