FIELD: engines and pumps.
SUBSTANCE: invention relates to engine production, particularly to diesel engine fuel feed components. Proposed HPFP section consists of plunger casing and barrel threaded together, plunger, union with pressure valve, electromagnetic control valve and fuel inlet and outlet channels. Note that sealing end of casing restricts pressure chamber above the plunger. Aforesaid threaded joint consists of the casing outer thread and plunger barrel inner thread. Note that high- and low-pressure channels are brought to the lateral sealing end face of the casing whereto aforesaid electromagnetic control valve is connected.
EFFECT: sufficient tightness of joints at high pressure of fuel feed thanks to absence of dead precision holes.
