Abstract
Control structure controls movement of a high pressure fuel pump piston of a fuel system. The piston is constructed and arranged to be inserted into or withdrawn from a pumping chamber to control a flow of fuel from the pumping chamber. The control structure includes a rocker arm with an associated roller follower. The roller follower is constructed and arranged to engage a camshaft of an engine. The rocker arm is operatively associated with the piston such that movement of the camshaft causes movement of the rocker arm and thus movement of the piston. The control structure also includes actuator structure associated with the rocker arm and constructed and arranged to vary a percentage of camshaft motion imparted to the piston via the rocker arm.
