Abstract
PURPOSE: To make a motion of a valve quicker while to plan to improve an accuracy of amount of flow by preventing a standing pressure wave by a method wherein fuel is fed through a fuel feeding hole provied near a valve seat, and a hole releasing the pressure wave from a back pressure side of the valve is provided so as to face the feeding hole.
CONSTITUTION: A valve 1 is guided by a valve sliding portion 1c, however, when the valve 1 is moved in high speed, a pressure wave is generated in a back pressure chamber 11 and is returned to a fuel feeding portion 5 through a back pressure hole 7. That means, when the valve 1 is sucked, a positive pressure wave is generated in the back pressure chamber 11 and increases a pressure in the feeding portion 5, therby, promotes an injection of fuel from a feeding hole 6, however, on the contrarry, when the valve 1 is closed, a negative pressure wave is applied on the feeding portion 5 from the back pressure chamber 11 and acts to stop the fuel. As described above, the pressure wave acts to help a motion of the fuel flowing from the feeding hole 6 at a proximity of the feeding portion 5 while the pressure wave is not delivered to a distant place within a pipe of feeding system, therefore, a standing wave is hardly generated within the pipe.
