Beschreibung
Zusammenfassung:	The invention relates to an oil injection port leakage preventing device. The oil injection port leakage preventing device comprises an oil injection nozzle and a ventilation pipe. An oil injection port is formed in one end of the oil injection nozzle. A fluid channel allowing oil to pass is arranged in the oil injection nozzle. A one-way communication device is arranged on the fluid channel. Theventilation pipe is arranged in the oil injection nozzle. One end of the ventilation pipe corresponds to the one-way communication device, and the other end of the ventilation pipe penetrates out of the side wall of the oil injection nozzle. The one-way communication device is provided with a first station and a second station. When the one-way communication device is located at the first station,the one-way communication device blocks a pipeline of the ventilation pipe, and the fluid channel is communicated; and when the one-way communication device is located at the second station, the one-way communication device b
