Abstract
PURPOSE: To reduce knocking of a diesel engine and generate a high power by communicating a pressure regulation chamber with a high pressure chamber which compresses a fuel oil to a high pressure and providing a means for controlling a set load on a spring which loads on a governing piston.
CONSTITUTION: A high pressure chamber 4 is formed on the head of a plunger 3 inside a plunger barrel 2 and communicated with a pressure regulation chamber 14. A governing piston 15 is loaded by a spring 16 and a means 23 for adjusting a set load on the spring 16 is provided. When the plunger 3 advances, a fuel oil in the high pressure chamber 4 is compressed to a high pressure and squeezed to an injection valve via a slit 8 and a delivery valve 10 in an outlet passage 11. The set load adjusting means 23 provides an aid for varying an injection pressure in the high pressure chamber 4 according to the load, thereby reducing knocking of a diesel engine and generating a high output power.
