FIELD: engines and pumps.SUBSTANCE: invention relates to production of engines, particularly to ICE fuel feed hardware. ICE high-pressure fuel pump comprises case with camshaft fitted therein to drive at least two plungers via multi-loge cam. Every said plunger is fitted in one of cylinder heads mounted at pump case to displace therein for conversion of their rotation in reciprocation of said plungers, hence, for suction of fuel from low-pressure line, for increase of fuel pressure to high pressure and for fuel feed in common high-pressure fuel line. Low-pressure unit is mounted at the case. Low-pressure unit side facing the high-pressure fuel pump incorporates high-pressure fuel batcher integrated in said unit, outside said case.EFFECT: high-pressure pump with multiple-version housing and well-protected batcher.7 cl, 1 dwg |
