Title:
DISTRIBUTOR TYPE FUEL INJECTION PUMP
Document Type and Number:
Japanese Patent JPH01177423
Kind Code:
A
Abstract:
PURPOSE:To precisely adjust a fuel injection amount in a maximum speed control range by moving the whole of a control lever and a tension lever with an adjustment means via a guide lever, and changing the lever ratio of the whole of each lever. CONSTITUTION:When an adjustment cam 63 is turned via the motion of an operation lever 65f from the outside of a pump casing 1, a guide lever 26 is pressed downward, depending upon the shape of a cam surface 63a and the guide lever 26 is displaced downward together with a tension lever 23 and a control lever 24. Then, as a distance from the rotation support point of the control lever 24 to the contact part of a governor sleeve 35 changes, the lever ratio of each lever 23 and 24 around a pivot 25 changes respectively. As a result, each torque from a control spring 38 and the governor sleeve 35 working on each lever 23 and 24 varies. The displacement of a spill ring 20 changes and a fuel injection amount is adjusted accordingly.
