NEGATIVE PRESSURE WAVE GENERATOR
PROBLEM TO BE SOLVED: To provide a negative pressure wave generator capable of generating a large negative pressure wave by enlarging an aperture area between a vacuum chamber aperture and a valve body and sufficiently reducing a tunnel micro atmospheric pressure wave.SOLUTION: A negative pressure wave generator 1 for cancelling out a tunnel micro atmospheric pressure wave W2 which is a positive pulse wave with a negative pressure wave W3 which is a negative pulse wave by using the negative pressure wave W3 generated in pulses to cause interference with the tunnel micro atmospheric pressure wave W2 projected as a pulse towards the outside from an exit 102 of a tunnel 100 comprises: a vacuum chamber 11 capable of maintaining a vacuum inside, a plurality of apertures 11a opened in the vacuum container 11, and a plurality of valve bodies 13 within the vacuum chamber 11 which respectively open and close the plurality of apertures 11a.SELECTED DRAWING: Figure 2
【課題】真空容器の開口部と弁体との間の開口面積を大きくすることにより、大きな負圧波を発生させて、トンネル微気圧波を十分に低減させることができる負圧波発生装置を提供する。【解決手段】トンネル１００の出口１０２から外部に向けてパルス状に放射されるトンネル微気圧波Ｗ２に対して、パルス状に発生させた負圧波Ｗ３を干渉させることにより、正のパルス波となるトンネル微気圧波Ｗ２を負のパルス波となる負圧波Ｗ３によって相殺する負圧波発生装置１であって、内部を真空状態に維持することが可能となる真空容器１１と、真空容器１１に開口する複数の開口部１１ａと、真空容器１１内において複数の開口部１１ａをそれぞれ開閉する複数の弁体１３とを備える。【選択図】図２
