摘要

A fuel injector regulator having combined initial injection and peak injection pressure regulation. The fuel injector regulator includes a rate shaping valve movably supported within a valve bore between a closed position and an open position to regulate a rate of injected fuel. The regulator further includes a waste gate valve having a body movably supported within a bore of the rate shaping valve and between a closed position and an open position to regulate the pressure of injected fuel.
