FIELD: engines and pumps.
SUBSTANCE: pump comprises a body (1), in which a driving shaft (2) is installed, which is rotated around its axis with a cam or an eccentric (3) protruding in radial direction, with which several plungers (5) installed in cylinders (4) interact, being serially moved with a cam or an eccentric (3) in the radial direction. The body (1) for fixation on the internal combustion engine is equipped with a mounting flange (6). The cylinders (4) are connected with fuel lines (10), which are partially arranged in the body (1). The mounting flange (6) and the body (1) are formed by independent parts. A low pressure unit (7) is fixed at the side of the body (1) facing from the mounting flange (6). The mounting flange (6) and the low pressure unit (7) are connected with the body (1) as capable of rotation relative to each other and relative to the body (1) and together limit circular channels (8), which concentrically cover the driving shaft (2) and which partially form the sections of fuel lines.
EFFECT: cheaper manufacturing.
