Title: Injection valve for injecting fuel into the combustion chamber of an internal combustion engine
IPC: F02M47/00
Filed: 2001-05-25
Abstract: An injection valve for injecting fuel into the combustion chamber of an internal combustion engine has an injector needle guided inside the housing in such a way that it can be displaced longitudinally with a shaft in order to open and close the injection cross-sections. The injector needle is actuated by the fuel pressure which act upon the injector needle and by a closing spring acting in the closing direction of the injection needle. The closing spring is pre-compressed between abutments on the injector needle and the housing and is situated on the perimeter of the injector needle in the area between the injector needle guide and the valve seat. One advantage of the arrangement is the compact construction of the injection valve and the low dead volume of the control chamber on the reverse side of the injector needle.

Abstract: PURPOSE: A top in a top is provided to produce a direct forwarding motion by combining a circular motion. CONSTITUTION: Two disks of the same mass are revolved and rotated in symmetrical to a revolution orbit, serving as a horizontal axis toward the center on the revolution orbit of a vertical axis. When the azimuth of the revolution orbit is bisected and the half of the number of rotation is increased and the other half is reduced constantly, a revolution centrifugal force with different phase and different size is produced on the rotary axis due to a difference of rotation number between the two rotating disks. The difference is exhibited in the form of a vertical motion.
