Document Type and Number:
Japanese Patent JPH039305
Kind Code:
B2
Abstract:
A fuel injection pumping apparatus for supplying fuel to an internal combustion engine comprises a rotary distributor member having a transverse bore mounting pumping plungers arranged to be moved inwardly by cam lobes on a cam ring. The outward movement of the plungers is controller by varying the axial position of the distributor member. Fuel flows from the bore by way of a delivery passage to an outlet and also when the distributor member is set to provide low fuel delivery through a restricted passage and a flow channel. The period in terms of degrees of rotation of the distributor member for a given displacement of fuel through the outlet is extended as compared with an apparatus in which the restricted passage and flow channel are not provided. The cam ring is also angularly adjustable and the restricted passage and flow channel are positioned so that flow of fuel through the restricted passage ceases as the cam ring moves angularly with increasing speed.
