FIELD: engines and pumps.
SUBSTANCE: invention can be used in ICE control and fuel feed systems. Proposed pump has housing (1) accommodating cam shaft or eccentric shaft to drive at least one plunger pair that runs in bearing about its lengthwise axis. To be fitted in said bearings, drive shaft has structural part (5) with bearing bore (6) connected with pump housing (1) with friction closure. To ensure said friction closure joint (7) said structural part has first and second sections (a) and (b). Said sections feature radial excess size relative to that arranged in pump housing (1) for locating bore (8). Said structural part (5) is fitted in the latter while said sections are spaced apart in drive shaft lengthwise axis.
EFFECT: simplified design, lower production costs.
