圧相当の圧搾空気を供給してエアシールするよう
構成した排気弁支持部のエアシール構造であつて
、機関の始動および停止に使用される空気圧力源
などの掃気圧以上の空気圧力源から前記排気弁支
持部に圧搾空気を導くようにし、この圧搾空気供
給路に、シリンダに掃気を供給する掃気供給路か
ら分岐した配管により掃気圧が作用し、排気弁支
持部に作用する圧搾空気の圧力を掃気圧より常に

の排気弁支持部のエアシール構造。 An air seal structure for an exhaust valve support part configured to supply compressed air equivalent to scavenging pressure to the exhaust valve support part of a cylinder of a marine internal combustion engine to form an air seal, such as an air pressure source used for starting and stopping the engine. Compressed air is guided to the exhaust valve support part from an air pressure source higher than the scavenging pressure of An air seal structure for an exhaust valve support part of a marine internal combustion engine, characterized by being provided with a diaphragm pressure regulating valve that always adjusts the pressure of compressed air acting on the valve support part to a pressure higher than scavenging pressure by a predetermined value.
