Abstract
PURPOSE: To obtain advance characteristic in several steps by installing a regulating valve in a feed pump chamber and allowing the flow rate from the pump chamber to be varied in the relation to the engine speed, due to the structure of the regulating valve.
CONSTITUTION: In a regulating valve 31, the pressure in a pump chamber 3 is applied to a slider 33 from underside, and the position of the slider 33 is determined by the set force composed of the area of the slider 33 the pressure inside the pump chamber and a spring 34, and fuel flows out from a hole 36. When the number of revolution of an oil feeding pump 2 increases, and passes through a point Ni, the slider 33 is elevated furthermore, and a hole 38 is opened. Accordingly, when the number of revolution of the oil feeding pump 2 becomes above the point Ni, the pressure in the pump chamber 3 shows a point of inflection at the point Ni, and after the point Ni of the number of revolution of the oil feeding pump, advance characteristic having a point of in flection as shown in the figure is obtaine d.
