To provide a sealed tank system including a pressure adjustment valve which can adjust fuel pressure using the atmospheric pressure as a reference without being affected by internal pressure in a fuel tank.SOLUTION: A sealed tank system 1 includes: a sealed fuel tank 12; a fuel pump 34 which supplies a fuel in the sealed fuel tank 12 to an internal combustion engine 16; and a pressure adjustment valve 44 which is disposed in the sealed fuel tank 12 and adjusts a pressure of the fuel supplied from the fuel pump 34 to the internal combustion engine 16. The pressure adjustment valve 44 has a pressure regulating chamber 84 and a back pressure chamber 82 which are partitioned by a diaphragm. Atmospheric air is introduced into the back pressure chamber 82 through an atmospheric air introduction passage 50 from the outside of the sealed fuel tank 12.SELECTED DRAWING: Figure 1

    【課題】燃料タンクの内圧の影響を受けることなく、大気圧基準で燃圧を調整できる圧力調整弁を備えた密閉タンクシステムを提供する。【解決手段】密閉タンクシステム1は、密閉式燃料タンク12と、密閉式燃料タンク12内の燃料を内燃機関16へ供給する燃料ポンプ34と、密閉式燃料タンク12内に配置されており、燃料ポンプ34から内燃機関16へ供給される燃料の圧力を調整する圧力調整弁44とを有する。圧力調整弁44は、ダイヤフラムによって区画された調圧室84と背圧室82とを有し、背圧室82には、密閉式燃料タンク12の外側から大気導入通路50を介して大気が導入される。【選択図】図1
