FIELD: engine engineering. SUBSTANCE: plunger pair has plunger with axial and radial passageways and plunger bushing with the inlet port. The plunger is made up as the part of a cylinder trancated by the plane parallel to its axis. The plunger bushing is made up as two parts conjugated with the plunger. The splitting plane of the parts is coincident with the flat plunger surface. The radial passageway of the plunger and inlet opening of the plunger bushing are made on the opposite sides and on the side of flat surface of the plunger, respectively.
