FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed high-pressure pump delivering fuel into internal combustion engine contains housing with at least one cylinder in which piston slides, and head with mating surface pointed to corresponding mating surface on housing to secure cylinder. Head is provided with suction and delivery pipelines. Suction pipeline has intake hole on mating surface of head. Housing is provided with feed pipeline with outlet hole on mating surface of housing near intake hole. First seal between mating surfaces is arranged around cylinder, and second seal, around intake hole. Seals are separate ones and are made of elastomer.
EFFECT: improved sealing of high-pressure pump.
