ABSTRACT:
A fuel pump drive system is provided. A system for an engine driven by an engine crankshaft may include a first variable cam device including a first hydraulic actuator, and a second variable cam device including a second hydraulic actuator. The system may further include an intermediate power transfer mechanism coupled between the first variable cam device and the second variable cam device upstream, in a direction of power flow from the engine crankshaft, of the first hydraulic actuator and the second hydraulic actuator. The system may further include an auxiliary device coupled to and driven by the intermediate power transfer mechanism. In this way, because the auxiliary device is driven via the intermediate power transfer mechanism and thus derives its power from upstream of the hydraulic actuator of the variable cam device, the actuator can be adjusted without having to overcome resistance torque of the auxiliary device.
