- 管水路Dに差圧式減圧弁10を介設し、その減圧弁10は、その弁体8が水密に摺動するシリンダ6に、導圧管25,26を介して流出室4の水圧を導入し、その導圧管25,26に圧力設定弁20を介設して、その圧力設定弁20により、前記流出室4の水圧に基づき、前記弁体8をシリンダ6内で移動させてその開閉度合を制御する減圧弁装置において、
前記圧力設定弁20と前記流出室4との間に位置する導圧管25に絞り部31aを設けるとともに、その絞り部31aに、リフト弁32aを介設したバイパス回路32を並列に設け、このリフト弁32aは、通常は閉じており、前記流出室4の圧力P2が所定圧以下になると開放するものであることを特徴とする減圧弁装置。 - 前記リフト弁32aは、その弁体38がバネ33により閉弁方向に付勢されており、前記バネ33の付勢力に抗して前記シリンダ6の水圧が印加されているとともに、前記流出室4の水圧が前記閉弁方向に印加されているものであり、前記流出室4の圧力P2が所定圧以下になると前記シリンダ6の水圧により前記弁体38が開放されることを特徴とする請求項1に記載の減圧弁装置。
