This paper undertakes the problem of applying a hypocycloid mechanism in the drive of pumping sections of high-pressure pumps for Diesel combustion engines. The authors have reviewed existing pump drive mechanisms, analyzed the weak links in existing solutions and discussed the latest trends in common rail systems. Further sections describe the design of a pump utilizing a hypocycloid mechanism, demonstrate beneficial functional features and present selected results of the assembly’s dynamic simulation. As a result of work, a pump model was developed, with operating parameters that do not deviate from those of the latest solutions of leading manufacturers, simultaneously eliminating the greatest flaws of existing pumps that lead to their premature wear.
