摘要： PROBLEM TO BE SOLVED: To provide a high pressure pump capable of reducing the weight of an intake valve for opening and closing a supply passage for supplying fuel to a pressurizing chamber.SOLUTION: The intake valve 40 closes the supply passage 100 by sitting on a valve seat 34 and opens the supply passage 100 leaving from the valve seat 34. A stopper 50 is arranged in the pressurizing chamber side of the intake valve 40 and regulating the movement of the intake valve 40 to the pressurizing chamber side. A needle 60 formed separately from the intake valve 40 can abut on the end face of the valve seat 34 side of the intake valve 40. The first spring 21 is contained in a containment chamber 52 arranged in the stopper 50 and biases the intake valve 40 to the valve seat 34 side. The length B in an axial direction of a guide part 41 extending from the end face of the stopper 50 side of the intake valve 40 is formed longer than the moving distance A when the suction vale 40 is fully closed and fully opened and regulates the movement in a radial direction of the intake valve 40. Consequently, it is possible to reduce the outer diameter of the intake valve 40 and to achieve thinning in an axial direction of the same.

摘要： PROBLEM TO BE SOLVED: To provide a high pressure pump capable of improving self close limitation of an intake valve with a simple configuration.SOLUTION: A pump body 11 has a pressurizing chamber 121 in which fuel is pressurized by the reciprocating movement of a plunger and a supply passage 100 guiding fuel to the pressurizing chamber 121. The outer diameter of a stopper 50 arranged in the pressurizing chamber 121 side of the intake valve 40 for opening and closing the supply passage 100 is formed larger than the outer diameter of the intake valve 40. A needle 60 constituted separately from the intake valve 40 can abut on the end face of the valve seat 34 side of the intake valve 40. The intake valve 40 has a guide 41 regulating the movement in the radial direction of the intake valve 40 in the end face of the stopper 50. Thereby, because the intake valve 40 is covered with a stopper 50 viewing from the pressurizing chamber 121 side, the dynamic pressure of fuel discharged from the pressurizing chamber 121 to the feed passage 100 is suppressed from acting on the intake valve 40 during a step of quantity adjustment of the high pressure pump.

摘要： PROBLEM TO BE SOLVED: To provide an electric power supply device for an exhaust emission control device whose purifying amount is improved. SOLUTION: The exhaust emission control device is equipped with the electric power supply device 50 (an electric power supply means) which is applied to an exhaust emission control system 10 for oxidizing and purifying PMs (particulate) within exhaust by executing a corona discharge from a discharging electrode 21 arranged in an exhaust passage 11 of an internal combustion engine, and repeats an instantaneous voltage application to the discharging electrode 21 two or more times to thereby supply electric power employed for the corona discharge. The time required for the instantaneous voltage application by the electric power supply device 50 is made shorter than a given time period (a predetermined time period) required for arc discharge. Accordingly, the arc discharge can be restrained from being generated and therefore an applied voltage can be driven to be higher, eventually enabling an increase in a PM purifying amount.
