ABSTRACT:
Exhaust valve mechanism in an internal combustion engine, comprising a piston-cylinder device (21,22) width a securely mounted cylinder (21), the piston (22) of which has a piston rod (37) which extends through a bore (38) in a rocker arm (8) and is directed towards the spindle end (6) of the exhaust valve (1). A valve (23) in a hydraulic circuit is controlled by the movement of the rocker arm and is arranged, when there is overpressure in the hydraulic circuit, to conduct pressure fluid to and from the cylinder (21) to open and close the exhaust valve (1) at a stroke other than the exhaust stroke.
