摘要： A fuel-feeding system may preferably include a fuel tank containing liquid fuel; a fuel pump capable of pumping the liquid fuel contained in the fuel tank; a fuel injection valve capable of injecting the liquid fuel pumped by the fuel pump; and a three-way valve having a first port, a second port and a third port. The three-way valve is constructed so as to be switched between a first condition in which the first, second and third ports communicate with each other and a second condition in which only the first and third ports communicate with each other. The fuel injection valve is connected to the third external conduit at a position between the third port and the second relief valve, so that a pressure of the liquid fuel fed to the fuel injection valve can be switched between the first setting pressure and the second setting pressure when the three-way valve is switched between the first condition and the second condition.

摘要： A body 20 has body wall surfaces 21, 22 defining a body space inside. A core 30 is disposed within the body 20. The core 30 has a core wall surface defining a core space inside which has a bottom having an opening 33a. A valve 50 is inserted through the opening 33a of the core 30 with a clearance and can move along the core wall surface of the core 30. The valve 50 has a hole with a bottom which is comprised of holes 52a, 53a, 57a, a contact surface 58 that contacts the core wall surface of the core 30, a valve head 59 that can contact a valve seat 40, at least one first communication hole 55 that provides communication between the hole 53a and a second inflow fuel passage 30a within the core space, and at least one second communication hole 54 that provides communication between the hole 52a and the first inflow fuel passage 21a, 22a within the body space.
