Zusammenfassung:The gas exchange valve arrangement for a piston engine comprises a gas exchange valve (1) and a spring (4) exerting a force on the gas exchange valve (1) for closing the valve (1). The arrangement further comprises a hydraulic fluid chamber (12), a locking piston (1C, 26) that is attached to the gas exchange valve (1) and provided with a piston surface (5A, 26A) delimiting the hydraulic fluid chamber (12) and facing towards the opening direction of the gas exchange valve (1), means (14) for introducing hydraulic fluid into the hydraulic fluid chamber (12), and means (17, 30) for preventing outflow from the hydraulic fluid chamber (12) when the gas exchange valve (1) is closed.
