摘要： PROBLEM TO BE SOLVED: To provide a fuel injection nozzle wherein fuel consumption and exhaust emission discharge of a combustion engine are improved.
SOLUTION: The fuel injection nozzle for the combustion engine includes a nozzle body with a cavity and a nozzle needle set in the cavity of the nozzle body to be axially movable. The cavity is separated into a valve seat hole and a blind hole continuing to the valve seat hole. A fuel injection passage is branched from the blind hole and the valve seat hole is formed in a conical shape tapered in a direction to the blind hole. An inner wall enclosing the valve seat hole is defined as a first valve seat surface. The nozzle needle includes a valve seat part and a tip end part continuing to the valve seat part. An outer circumference of the valve seat part is a tapered conical shape and the outer circumference is defined as a second valve seat surface. As the second valve surface is set to cooperate with the first valve seat surface, a valve capable of controlling a flow rate cross section is formed. The blind hole is formed to be a conical shape tapered in a direction toward a bottom of the blind hole.

摘要： PROBLEM TO BE SOLVED: To reduce the action of the high-temperature in the combustion chamber of a cylinder on a nozzle cap 7 in a fuel injector which has a jetting nozzle with a generally tube-like nozzle body 2 in which a needle valve 3 is installed and which extends along the guided longitudinal axis A, and in which the nozzle body 2 comprises at least one jetting opening 6 in a nozzle cap 7 on the combustion chamber side for jetting a fuel into the combustion chamber of the cylinder of an internal combustion engine, and the nozzle body 2 is built in an injector insertion hole 8 of the cylinder head 9 of the cylinder. SOLUTION: The outer peripheral surface 10 of the portion 11 of the nozzle body near the combustion chamber is tapered toward the combustion chamber or sharpened. Therefore, the cross sectional area of the portion 11 of the nozzle body near the combustion chamber is continuously increased from the nozzle cap 7 to the fixed stage part 12 of the portion 11 of the nozzle body near the combustion chamber. The ratio of the combustion chamber side diameter of the nozzle to the diameter of the cylinder of the internal combustion engine is 0.08 to 0.11. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a sealing device for sealing a sealing region between components or between component portions to which a high pressure medium is introduced through a passage or a passage portion, particularly, a high pressure sealing region between the components or between the component portions of a fuel injection device for an internal combustion engine, capable of being inexpensively manufactured with its low-accuracy sealing surface cooperative in the high pressure sealing region. SOLUTION: On an opposed face 15 of one of the components 11, 12 or the component portions located opposing each other at a site on its passage 13 or its passage portion, a recessed site 17 is provided for increasing the inner diameter of the passage or the passage portion. An annular or tubular bush 18 is arranged in the recessed site 17. In a semi-assembled condition, the bush 18 is partially protruded from the recessed site 17 to come into contact with an opposed face 16 of the other component 12 or the component portion. During assembly, the bush 18 is deformed so that the opposed faces 15, 16 of the components 11, 12 or the component portions attach each other. COPYRIGHT: (C)2008,JPO&INPIT
