摘要： PROBLEM TO BE SOLVED: To remove impurities adhered to the periphery of the valve seat of a pressure control valve provided on a common rail automatically in an accumulative fuel supply device in an engine. SOLUTION: In order to control the pressure in an accumulation chamber higher than the open valve pressure of a pressure control valve 25 for a certain period of time at fixed timing when an engine is in operation, the valve element and the valve seat of the pressure control valve 25 are separated forcibly, and then adhered matter around the valve seat are removed by high pressure fuel low on the low pressure side around the valve seat. The adherence prevention control of this nature can be carried out at each fixed timing, for example, at acceleration or deceleration of the engine. Hence, when an internal pressure in the accumulation chamber rises excessively for some reason when the engine is in operation, the pressure control valve 25 opens properly to prevent a common rail 4, injectors 2, and a supply pipe 5 and the like from being damaged.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device promoting further atomization of injected fuel.
SOLUTION: A injection hole 61 and a plate part 64 are formed on an injection hole plate 60. The plate part 84 is arranged between a fuel inlet and a fuel outlet of the injection hole 61. The plate part 64 is arranged roughly vertically on an axis of the injection hole 61. Fuel is injected to a combustion chamber of an engine from the fuel outlet after flowing in the injection hole 61 from the fuel outlet and impinging on the plate part 64. Fuel is broken into minute droplets by impinging on the plate part 64. Consequently, fuel atomized once by flowing in the injection hole 61 of the injection hole plate 60 is atomized more by impinging on the plate part 64.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve increasing magnetic attraction force or a fuel injection valve preventing variation of fuel injection quantity with suppressing increase of manufacturing cost.
SOLUTION: A non-magnetic member 14 covers an outer periphery side of a cap 100 formed between a movable core 30 and an attraction member 44 over both of the movable core 30 and the attraction member 44. The non-magnetic member 14 prevents short of magnetic flux between a valve holder 12 and a connecting member 40 and prevents leak of magnetic flux to an outer periphery side from the movable core 30 and the attraction member 44 without passing through the cap 100. The connecting member 40 is provided with a projection part 42 cylindrically extending to the movable core 30 side on the outer periphery side. The projection part 42 stores the attraction member 44 in an inner periphery side and positions the attraction member 44. The attraction member 44 is formed out of more ferromagnetic material than the connecting member 40. A spring 48 is guided in an expansion direction on at least either one of inner periphery surfaces of the movable core 30 and the attraction member 44.
