FIELD: engines and pumps.
SUBSTANCE: invention can be used in fuel feed systems of compression initiated ignition ICE. Proposed high-pressure pump (1) comprises cylinder head (2) and pump assembly (6). Note here that cylinder head (2) has cylindrical bore (4) for pump assembly (6) plunger (5) to be fitted to displace therein. Said pump assembly (6) plunger (5) confines above-plunger cavity (12) in said cylinder head bore (4). Besides, inlet valve (20) is integrated in cylinder head (2) to force fuel in said above-plunger cavity (12). Control over inlet valve (20) allows an adequate batching of fuel fed to above-plunger cavity (12).
EFFECT: simplified design, lower costs, adequate control over fuel batching.
