Patent number: 9562503Abstract: In a nozzle, in a cross section including an axis of a nozzle body, a side surface and a seat surface are both smoothly connected to an arc of a circle inscribing both the side surface and the seat surface. A part of a needle which is adjacent to a tip end side of a seat portion is a cone having a diameter reduced toward a tip end side of the cone in the axial direction. Thus, no corner is on the seat surface or the side surface, and the two surfaces form one curved surface. Since a cavitation generated in a sack chamber can be reduced, even when an injection quantity is significantly small such that an injection port does not throttle an injection flow, a flow coefficient of the injection flow is improved and a penetration of a spray of the fuel can be maintained.Type: GrantFiled: January 20, 2015Date of Patent: February 7, 2017Assignee: DENSO CORPORATIONInventors: Toshiaki Hijima, Fumiaki Arikawa, Motoya Kanbara, Yuuta Hashimoto, Atsushi Utsunomiya, Kazufumi Serizawa, Shinya Sano

Publication number: 20160215746Abstract: In an injection hole of a nozzle, a maximum value of a longitudinal length of an inlet, which is measured in a direction of an inlet longitudinal axis of the inlet, is larger than a maximum value of a longitudinal length of an outlet, which is measured in a direction of an outlet longitudinal axis of the outlet. A rear end edge of an opening edge of the inlet is shaped into an arc. When the maximum value of the inlet is made larger than the maximum value of the outlet, an upstream end of the inlet can be placed at a further upstream side, so that a turn angle of a fuel flow can be reduced to increase the flow coefficient. Furthermore, when the rear end edge is shaped into the arc, the maximum value of the inlet can be increased.Type: ApplicationFiled: January 20, 2016Publication date: July 28, 2016Inventors: Kazufumi SERIZAWA, Shinya SANO, Atsushi UTSUNOMIYA
