Abstract

A lever electromechanical valve actuator assembly and arrangement of electromechanical valve actuators that creates a compact actuator assembly to increase ease of serviceability, provide space for engine components and eliminate interference between the actuators and components in the vehicle engine compartment.

Claims (30)

1. A lever electromechanical valve actuator assembly for a vehicle engine having cylinders and a cylinder head with a longitudinal cylinder extent, the cylinder head being disposed between the lever electromechanical valve actuator assembly and the cylinders, said electromechanical valve actuator assembly comprising:

a first actuator having a first pivot axis;

a second actuator having a second pivot axis, said first and second pivot axes each being approximately within forty five degrees of perpendicular to the longitudinal cylinder extent.

2. The lever electromechanical valve actuator assembly of claim 1 wherein said pivot axes are approximately perpendicular to the longitudinal cylinder extent.

3. The lever electromechanical valve actuator assembly of claim 1 wherein each of said first and second actuators include a longitudinal actuator extent and wherein said cylinder head includes a lateral cylinder head extent, said first and second actuators being approximately aligned along their longitudinal actuator extents with said lateral cylinder head extent.

4. The lever electromechanical valve actuator assembly of claim 1 wherein said first and second actuators each further include a pivot end and a lever end and wherein said first and second actuators are arranged so that said each of said lever ends are in closer proximity than said lever ends are to said pivot ends and said lever ends are in closer proximity than said pivot ends are to each other.

5. The lever electromechanical valve actuator assembly of claim 1 wherein said first and second actuators are each intake actuators associated with a cylinder, said first and second actuators being coupled together in a housing.

6. The lever electromechanical valve actuator assembly of claim 1 wherein said first and second actuators are each intake actuators and wherein said first actuator is associated with a first cylinder and wherein said second actuator is associated with an adjacent cylinder, said actuators being coupled together in a housing.

7. The lever electromechanical valve actuator assembly of claim 6 further including a hinge pin and wherein said first and second actuators are each coupled to said hinge pin.

8. The lever electromechanical valve actuator assembly of claim 1 further including a valve coupled to said first actuator, said valve including a valve head having a diameter, said diameter being extended toward said actuator and wherein said first actuator includes a first bolt and a second bolt for securing said first actuator to the cylinder head and wherein a line may be extended between the centers of said first and second bolts, said line being located at least partially within said extended diameter of said valve head.

9. The lever electromechanical valve actuator assembly of claim 8 wherein said valve is movable between an open position and a closed position along a valve axis and said line approximately intersects said valve axis.

10. The lever electromechanical valve actuator assembly of claim 1 further including a housing defining a first bolt hole and a bolt slot.

11. A lever electromechanical valve actuator assembly for a vehicle engine having cylinders and a cylinder head defining spark plug holes and having a longitudinal cylinder head extent, the cylinder head being disposed between the lever electromechanical valve actuator assembly and the cylinders, said electromechanical valve actuator assembly comprising a first actuator having a first pivot axis approximately aligned between two adjacent spark plug holes and approximately aligned with the longitudinal cylinder head extent.

12. The lever electromechanical valve actuator assembly of claim 11 wherein said spark plug holes are aligned along a cylinder longitudinal extent and wherein said first pivot axis is displaced laterally from the cylinder longitudinal extent.

13. The lever electromechanical valve actuator assembly of claim 11 further including a second actuator having a second pivot axis approximately aligned between two adjacent spark plug holes and approximately aligned with said first pivot axis.

14. The lever electromechanical valve actuator assembly of claim 13 wherein said spark plug holes are aligned along cylinder longitudinal extent and wherein said first pivot axis and said second pivot axis are displaced laterally from said cylinder longitudinal extent.

15. The lever electromechanical valve actuator assembly of claim 13 wherein said first actuator is operationally associated with a first cylinder and said second actuator is operationally associated with a second cylinder adjacent to said first cylinder.

16. The lever electromechanical valve actuator of claim 15 further including third actuator operationally associated with said first cylinder, said third actuator being offset along the cylinder head longitudinal extent from said first actuator.

17. The lever electromechanical valve actuator assembly of claim 14 wherein said third actuator includes a third pivot axis, offset laterally from said first and second pivot axes, and wherein said third pivot axis is approximately aligned with said second actuator along the cylinder head longitudinal extent.

18. The lever electromechanical valve actuator assembly of claim 17 wherein said pivot axes are approximately parallel.

19. The lever electromechanical valve actuator assembly of claim 11 further including a second actuator having a second pivot axis approximately aligned with said first pivot axis.

20. The lever electromechanical valve actuator assembly of claim 11 wherein said first actuator includes a first armature plate having a first protrusion.

21. The lever electromechanical valve actuator assembly of claim 20 further including a valve coupled to said protrusion.

22. A lever electromechanical valve actuator assembly for a vehicle engine having cylinders and a cylinder head defining spark plug holes and having a longitudinal cylinder head extent, the cylinder head being disposed between the lever electromechanical valve actuator assembly and the cylinders, said electromechanical valve actuator assembly comprising:

a first actuator having a first pivot axis approximately aligned between two adjacent spark plug holes and approximately aligned with the longitudinal cylinder head extent and wherein said first actuator includes a first armature plate having a first protrusion; and

a second actuator having a second armature plate with a second protrusion and wherein said first and second actuators include a longitudinal actuator extent, said first and second actuators being offset along their longitudinal actuator extents relative to each other.

23. The lever electromechanical valve actuator assembly of claim 22 wherein said actuators each include a lever end, and wherein each of said protrusions extend a protrusion distance from said respective lever end, and wherein said lever end of said first actuator is spaced less than said protrusion distance from said lever end of said second actuator.

24. A lever electromechanical valve actuator assembly for a vehicle engine having cylinders and a cylinder head with a longitudinal cylinder head extent, the cylinder head being disposed between the cylinders and the electromechanical valve actuator assembly, said electromechanical valve actuator assembly comprising:

a first actuator having a first core and a first power coil;

a second actuator having a second core and a second power coil and wherein each of said power coils form an end turn on at least one end of each of said first and second cores, said end turns extending a distance beyond said at least one end of each of said first and said second cores and wherein said first core and said second core are arranged so that said first core and said second core are displaced less than two times said distance apart.
