The invention relates to a valve arrangement for preventing siphoning effect in an engine (1) which at least in part is arranged below a water line (5), comprising a first conduit (9) and a pump (11) for feeding water from the ambience of the vessel to said engine (1) through the conduit (9), with at least a portion (9') of the conduit (9) having an extension above the water line (5), and a valve arrangement (14) for alternating sealing and opening of said portion (9'). The valve arrangement is characterized in that the valve device (14) is connected to a canal (18) for feeding a pressurized media, with the function of the valve arrangement (14) being controlled depending on the pressure in said canal (18). By means of the invention, an improved valve arrangement is provided, especially for sailboats equipped with engines, using which it is possible to prevent water from leaking into the engine (1) due to siphoning effects. |
