<p>A control arrangement for a gas exchange valve in a piston engine adapted between the camshaft of the engine and the valve mechanism, which control arrangement comprises a body part and a chamber arranged therein, into which chamber a connection for hydraulic medium opens and in which a piston device is arranged in force transmission connection with the camshaft and the valve mechanism. The connection for hydraulic medium opens to a space in the chamber, which space increases as the piston device moves in the opening direction of the valve, whereby hydraulic medium is arranged to flow into the space, when the valve is being opened, and out of the space, when the valve is being closed.</p> |
