Abstract
The present invention relates to engines having multiple hydraulic devices. For instance, in a typical multi-cylinder diesel engine, each cylinder includes an intake valve, an exhaust valve, a fuel injector and an engine brake. It is common for each of these devices to be controlled by an individual actuator. However, engineers have learned that decreasing the number of engine components can increase engine robustness. Therefore, the present invention utilizes a single rotary actuator to control multiple hydraulic devices for an engine cylinder.
