PROBLEM TO BE SOLVED: To provide a highly efficient system capable of preventing secondary disaster.SOLUTION: In the special fire-fighting vehicle, water is discharged by using a water discharger 1, and a device driven by hydraulic pressure actuators 3-8 is mounted. The special fire-fighting vehicle includes: a non-positive-displacement pump 21 and a positive-displacement pump 22 driven by a power source (an engine 30) a fire-fighting water suction path 31 to guide water to a suction port of the non-positive-displacement pump 21 a fire-fighting water supply path 41 to feed water discharged from the non-positive-displacement pump 21 to the water discharger 1 an actuation water suction path 32 to guide water discharged from the non-positive-displacement pump 21 to a suction port of the positive-displacement pump 22 a direction selector valve 35 to change the direction of flow of water discharged from the non-positive-displacement pump 21 to the fire-fighting water supply path 41 and to the actuation water suction path 32 and an actuation water supply path 42 to feed water discharged from the positive-displacement pump 22 to the hydraulic pressure actuators 3-8.COPYRIGHT: (C)2009,JPO&INPIT【課題】二次災害を防止し高効率のシステムを提供する。【解決手段】放水具1を用いて放水を行うとともに、液圧アクチュエータ3~8によって駆動される機器を搭載する特殊消防車両であって、動力源(エンジン30)によって駆動される非容積ポンプ21及び容積ポンプ22と、水を非容積ポンプ21の吸込口に導く消防水吸込通路31と、非容積ポンプ21から吐出される水を放水具1に供給する消防水供給通路41と、非容積ポンプ21から吐出される水を容積ポンプ22の吸込口に導く作動水吸込通路32と、消防水供給通路41と作動水吸込通路32とに対して非容積ポンプ21から吐出される水の流れ方向を切換える方向切換弁35と、容積ポンプ22から吐出される水を液圧アクチュエータ3~8に供給する作動水供給通路42とを備える。【選択図】図1
