To provide a suction vehicle that can prevent negative pressure from decreasing as a temperature of sealed water becomes high in a water-sealed pump of the suction vehicle.SOLUTION: The suction vehicle comprises: a receiver tank 5 that collects an object to be collected; and a water-sealed pump 25 that generates an air flow by pressurizing and depressurizing internal air of the receiver tank 5, wherein an ejector 30 that introduces air with a pressure higher than an upstream side of piping as drive air is provided in the piping connecting the receiver tank 5 and the water-sealed pump 25.SELECTED DRAWING: Figure 1A
【課題】吸引車の水封式ポンプにおいて、封水が高温になるにつれて負圧が低下するのを防止する。【解決手段】回収対象物を回収するレシーバタンク５と、このレシーバタンク５の内部エアを加減圧してエアの流れを発生させる水封式ポンプ２５とを備えた吸引車において、レシーバタンク５と水封式ポンプ２５とをつなぐ配管に、配管の上流側よりも高い圧力のエアを駆動エアとして導入するエゼクタ３０を介設する。【選択図】図１Ａ
