Title: Fluid injection valve
Inventor: MAKIYAMA TAKASHI
IPC: F02M51/06
Filed: 2003-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fluid injection valve capable of injecting a prescribed quantity of fluid.  <P>SOLUTION: The fluid injection valve has a nozzle needle, stopper, etc. to form a part 23 to be engaged, and the lift of the nozzle needle is decided by the part 23 abutting to the stopper 24. At a constant spacing approximately, ring-shaped grooves 23b having a depth of 0.1 mm or more are formed at the first abutting surface 23a of the part 23 abutting to the second abutting surface 24a of the stopper 24. This reduces the contacting area of the first abutting surface 23a with the second abutting surface 24a, and the fluid flows to between the first abutting surface 23a and the second abutting surface 24a. This reduces the squeezing force generated between the first abutting surface 23a and the second abutting surface 24a, which facilitates separation of the part 23 from the stopper 24 when the fluid injection is shut off, precludes a delay of the valve closing starting time, and prevents the fluid injection time from prolonging. Accordingly it is possible to inject the prescribed quantity of fluid.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
