A fuel-feeding device may preferably include a pressure control valve capable of controlling a pressure of pressurized fuel that includes a housing having an inner cavity, a first movable dividing wall, a second movable dividing wall, a valve unit and a resilient member. The first and second movable dividing walls divide the housing cavity to a pressure controlling chamber, a back pressure chamber, and an open chamber positioned between the pressure controlling chamber and the back pressure chamber. The second movable dividing wall is arranged and constructed to move to a retracted position or an advanced position depending upon whether back pressure fuel is introduced into the back pressure chamber, thereby setting the resilient member to two different set loads. |
