Pressure relief device for engine room of a small watercraft |
摘要 |
A pressure relief device for an engine room of a small watercraft. The engine room is defined by an engine encasement, has an engine inside and is hermetically sealed with an engine cover. The pressure relief device has an opening provided in the engine encasement and a one-way valve which closes watertightly the opening through a grommet under normal conditions when the engine room pressure is below a given level of pressure, while it opens only outwards when the inside pressure goes up over the given level. It is desirable to employ a fastening member to secure the one-way valve on the opening in the engine encasement.
