Description

При включении вентил тора продувки поршень 4, настроенный по весу на давление всплыти , всплывает, открыва  отверстие в обечайке 2, после чего осуихествл етс  продувка корпуса двигател . Уровень жидкости в емкости 5 поршн  4 становитс  выше уровн  жидкости в емкости 8 и по гибкому шлангу 7 через регулируюш.ий вентиль 9 происходит перетекание жидкости из емкости 5 в емкость 8. По мере перетекани  жидкости и уменьшени  веса поршн  происходит постепенное всплывание поршн  до тех пор, пока давление под поршнем не превысить его веса. В этот момент поршень перемеш,аетс  в верхнее положение , перекрыва  отверстие в обечайке 3 и герметизиру  корпус двигател .When the purge fan is turned on, the piston 4, which is tuned to the pressure to ascend, pops up, opening an opening in the sidewall 2, after which the engine body is purged. The fluid level in the reservoir 5 of the piston 4 becomes higher than the fluid level in the reservoir 8 and through the flexible hose 7 through the regulating valve 9, the fluid flows from the reservoir 5 to the reservoir 8. As the fluid flows and the weight of the piston decreases, the piston gradually floats up until the pressure under the piston exceeds its weight. At this moment, the piston is displaced to its upper position, closing the opening in the shell 3 and sealing the engine housing.

При выключении вентил тора продувки поршень 4 иод действием собственного веса опускаетс  вниз, перекрыва  отверстие в обечайке 2.When the purge fan is turned off, the piston 4 iodine down with its own weight, blocking the opening in the shell 2.
