Abstract (en)
[origin: WO2014106681A1] The exhaust valve arrangement for a piston engine comprises force transmission means (2, 3, 14, 19) that are arranged between a cam (1) and an exhaust valve (13). Hydraulic fluid can be introduced into a fluid chamber (4) during the opening movement of the exhaust valve (13). A piston (7) is arranged in the fluid chamber (4) and connected to the force transmission means (2, 3, 4,19). By controlling outflow from the chamber (4), the closing speed of the exhaust valve (13) can be controlled. Outflow from the chamber (4) is allowed at a rate that allows the closing curve of the exhaust valve (13) to follow the cam curve at least until the exhaust valve (13) has moved a certain predetermined distance in the closing direction.
