Abstract

The invention relates to an arrangement (1) for operating a gas exchange valve (2) of a piston engine. The arrangement comprises a hydraulic actuator (3) for moving the gas exchange valve (2) toward an open position by pressure of hydraulic fluid acting in a pressure chamber (7) of the hydraulic actuator (3), a hydraulic fluid source, (11) and a drain line(15). The arrangement (1) further comprises a proportional control valve (17) having a valve member (19) and an electrical actuator (18) arranged to directly move the valve member(19). The valve member(19) is movable to a first main position, in which the control valve (17) is arranged to connect the hydraulic fluid source (11) to the pressure chamber (7), and a second main position, in which the control valve (17) is arranged to connect the pressure chamber (7) to the drain line (15).
