FIELD: engines and pumps.
SUBSTANCE: invention relates to production of engines, particularly to ICE fuel feed hardware. High-pressure pump for ICE fuel injection system with common high-pressure line ("common tail" system) has driving shaft running in at least one bearing. Said bearing is fitted in drain hydraulic line with at least one valve arranged downstream of said bearing. Pressure of valve opening makes 0.1-0.8 bar.
EFFECT: minimised bearing oil leaks.
