Abstract
Disclosed herein is an actuator for regulating the flow of fluids in first and second flow paths of an internal combustion engine. The actuator includes a motor having a rotatable drive shaft, a gear assembly driven by the drive shaft of the motor, and first and second output shafts rotated in opposite directions by the gear assembly. The first and second output shafts are operatively linked to valves in the first and second flow paths, respectively, to regulate the flow of fluids in the first and second flow paths.
Claims28
An actuator for regulating the flow of fluids in a first flow path and a second flow path of an internal combustion engine, the actuator comprising:
- a motor having a rotatable drive shaft;
- a gear assembly driven by the drive shaft of the motor;
- a first output shaft rotated by the gear assembly to regulate the flow of fluids in the first flow path;
- and
- a second output shaft rotated by the gear assembly to regulate the flow of fluids in the second flow path;
- wherein the first output shaft and the second output shaft rotate in opposite directions.
An intake manifold assembly with an actuator for regulating the flow of fluids in a first flow path and a second flow path of an internal combustion engine, the assembly comprising:
- an intake manifold having the first flow path and the second flow path;
- and
- an actuator as a component of the intake manifold, the actuator comprising:
- a motor having a rotatable drive shaft;
- a gear assembly driven by the drive shaft of the motor;
- a first output shaft rotated by the gear assembly to regulate the flow of fluids in the first flow path;
- and
- a second output shaft rotated by the gear assembly to regulate the flow of fluids in the second flow path;
- wherein the first output shaft and the second output shaft rotate in opposite directions.
