とを特徴とする筒内噴射用燃料噴射ノズル。 a fuel supply valve consisting of a nozzle holder disposed facing the inside of the cylinder; a housing and a first valve body fitted into the nozzle holder; A first member that is fitted onto the housing and is compressed between the housing and the housing.
a cylinder that is pressed against the tip surface of the nozzle holder by a spring, has a nozzle hole formed at its tip, and has a fuel chamber defined by the housing end surface; a second valve body that faces the end surface of the housing and whose other end closes the nozzle hole by a second spring contracted between the cylinder tip and the combustion supply valve; The valve body opens to supply fuel to the fuel chamber, the cylinder moves upward against the first spring force when the cylinder pressure exceeds a predetermined value, and the second valve body 1. A fuel injection nozzle for in-cylinder injection, characterized in that one end of the cylinder comes into contact with an end surface of the first valve body as the cylinder moves upward, and is then pushed down against the spring force of a second spring.
