Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; diesel engines. ^ SUBSTANCE: invention relates to fuel feed pumps of diesel engines. Proposed plunger pair contains barrel with two symmetrical filler holes. Holes are made tangentially to inner surface of barrel. They are connected with low-pressure space arranged in pump head. Plunger pair contains also cutoff hole in barrel and plunger with axial and radial holes, and control grooves engaging with cutoff hole. Ring groove is made on plunger connected by radial and axial holes with overplunger space. Filler holes are directed tangentially to ring groove on plunger. Filler holes are arranged under cutoff hole or over cutoff hole. ^ EFFECT: reduced wear and improved manufacturability of plunger pair. ^ 6 dwg
