FIELD: engine engineering. SUBSTANCE: system has high- pressure fuel pump made up as housing and crankcase. The plungers mounted inside the housing to form a low- pressure space and delivery space. A spring loaded pusher is mounted inside the crankcase to form a space of variable volume. A sealing unit is interposed between the pusher and crankcase. The system is additionally provided with hydraulic accumulator, batching valve, and eccentric. The hydraulic accumulator is in communication with the low-pressure space. The batching valve is mounted inside the plunged for permitting its end face to interact with the eccentric and for permitting communication of the low-pressure space with the delivery space. EFFECT: enhanced efficiency. 1 dwg
