ABSTRACT:
Pump body has a cylindrical chamber within which a spool-shaped insert fits. The insert has a central cylindrical bore within which the injection plunger works and has an external annular groove communicating with the bore through a lubricant supply port having a diameter smaller than that of the bore. Lubricant is furnished to the bore through an opening in the pump body which communicates into the annular space defined by the insert groove. The fit between the plunger and bore is interrupted only through the arcuate extent of the diameter of the lubricant supply port.
