特徴とするメータリングポンプ。[Claims for Utility Model Registration] A first plunger is moved by a drive shaft that reciprocates in the axial direction as it rotates, and the volume of a pump chamber between the first plunger and a fitted second plunger is made variable. In a metering pump that supplies oil to the engine by intermittent suction and discharge passages, a cam pin is provided protruding from the drive shaft, and a stand is fixed to the cam shaft at a position where it can come into contact with the cam pin. A conical taper cam is arranged, and the camshaft is moved linearly in the axial direction by a motor equipped with a screw mechanism that converts rotational motion into linear motion, and the contact position with the cam pin is determined by moving the tapered cam in the axial direction. A metering pump characterized in that the stroke of the first plunger is made variable to control the amount of oil supplied.
