A water piston type marine water spraying propeller comprises an air inlet pipe, a one-way air inlet valve, an air cylinder, an oil spraying nozzle, an ignition device and a water spraying pipe. Whenthe propeller is placed in water, water enters the propeller from the water spraying pipe, and meanwhile air enters the air cylinder from the air inlet pipe through the one-way air inlet valve. More and more air and water enter; the air density is much lower than that of water; water and air are in a layered state; after reaching a certain water level, one-way intake valve closure, the water levelcontinues to rise, air in the air cylinder is compressed, after the air pressure reaches a certain degree, the oil nozzle sprays out fuel oil, the ignition device ignites (spontaneous combustion canbe achieved even without ignition when the air pressure is large enough), the mixed gas burns to generate high-temperature and high-pressure gas, the high-energy gas extrudes water in the air cylinderto be sprayed out of the water spraying pipe, and water spraying reacting force pushes the ship to advance. The water piston type marine water-jet propeller is a water-jet propelling mode which is simple in structure and high in efficiency.
一种水活塞式船用喷水推进器,包括进气管、单向进气阀、气缸、喷油嘴、点火装置、和喷水管。本推进器置于水中时,水从喷水管进入推进器中,同时空气从进气管经单向进气阀进入气缸内。随着进入的空气和水越来越多,由于空气密度比水低得多,水和空气呈分层状态,到达一定水位后,单向进气阀关闭,水位继续上升,压缩气缸内空气,气压达到一定程度后,喷油嘴喷射出燃油,点火装置点火(气压足够大时甚至不用点火就可以自燃了),混合气燃烧产生高温高压气体,高能气体挤压气缸内的水从喷水管中喷射而出,喷水反作用力推动船体前进。水活塞式船用喷水推进器是一种结构简单,高效率的喷水推进方式。
