ABSTRACT:
An actuator assembly that uses a fluctuating operational pressure generated by an injector oil pump to actuate an EGR valve is disclosed. The operational pressure is used to operate the actuator assembly without being adversely affected by the fluctuating nature of the operational pressure. The actuator assembly includes an actuator housing defining a chamber and an actuator oil inlet. The actuator oil inlet is in fluid communication with the pump outlet. The actuator assembly further includes a slider located within the chamber. The slider is positionable between a first slider position and a second slider position. The slider isolates the actuator oil inlet from the chamber when the slider is located in the first slider position. The actuator oil inlet is in fluid communication with the chamber when the slider is located in the second slider position. The actuator assembly still further includes a movement assembly for moving the slider between a first slider position and a second slider position. The fluctuating operational pressure moves the actuator piston from the first piston position to the second piston position when the slider is located in the second slider position. A method of actuating a valve in an engine assembly is also disclosed.
