Abstract: A fuel injection pump includes a cam rotating with a camshaft, a cam ring revolving around the camshaft, a housing, plungers for pressurizing and pressure-feeding fuel drawn into fuel pressurizing chambers, and a rotary pump for supplying the fuel to the fuel pressurizing chambers. The housing includes a first housing portion for rotatably housing the rotary pump and second housing portions for housing the plungers so that the plungers can reciprocate. A filter is disposed in one of an outlet portion of a first low-pressure fuel passage in the first housing streaming the fuel from the rotary pump toward the fuel pressurizing chamber, an inlet portion of a second low-pressure fuel passage of the second housing portion facing the outlet portion, and a certain point in the second low-pressure fuel passage.

Abstract: A fuel injection pump includes a camshaft, an eccentric cam, a cam ring, a housing and plungers. The camshaft is rotated by an engine. The cam is provided separately from the camshaft and is formed with a connecting portion connected with the main shaft. The cam rotates with the camshaft. The cam ring revolves around the camshaft so that the cam ring rotates with respect to the cam along an outer periphery of the cam. The housing rotatably houses the cam and the cam ring and is formed with fuel pressurizing chambers. The plungers reciprocate in accordance with the revolution of the cam ring to pressurize and to pressure-feed fuel drawn into the fuel pressurizing chambers. Strength of the connecting portion is set to a value lower than damage strength of the housing.
