Title: Fuel injection valve
Inventor: NAKATSU AKIRA
IPC: F02M61/10
Filed: 2005-06-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of avoiding a sliding clearance from being increased by canceling the force of deforming the inside diameter of a sliding hole in the expanding direction by the force of deforming the inside diameter side of a recess in the contracting direction.  <P>SOLUTION: In the fuel injection valve, a recess 37 is formed on the outer circumferential surface of a nozzle body 21. The recess 37 laps a boundary between a sliding hole 23 and a fuel sump 24 in the radial direction. The recess 37 is a dent or a groove in the inside diameter direction, and formed continuously or partially at an equal interval over the entire circumference of the outer circumferential surface of the nozzle body 21. By forming the recess 37, the deforming force in the contracting direction is generated in the boundary β between the sliding hole 23 and the fuel sump 24 when the nozzle body 21 is applied with a load in the axial direction by the tightening force of a retaining nut 22. Expanding forces of the sliding hole 23 and a thin-walled part α can be canceled by the contracting force, and an increase in the leakage and the breakage of the thin-walled part α can be prevented.  <P>COPYRIGHT: (C)2007,JPO&INPIT
