Abstract

A valve lifter guide ( 100 ) includes a base ( 111 ) and at least one conduit ( 101 ) extending from the base ( 111 ). The conduit ( 101 ) has a first inwardly curved surface ( 103 ) opposed to a second inwardly curved surface ( 105 ) such that the conduit is capable of holding a valve lifter ( 200 ) between the first inwardly curved surface ( 103 ) and the second inwardly curved surface ( 105 ).

Claims (26)

1. A valve lifter guide comprising:

a base;

at least one conduit extending from the base, wherein the conduit has a first inwardly curved surface opposed to a second inwardly curved surface such that the conduit holds a valve lifter between the first inwardly curved surface and the second inwardly curved surface while preventing rotation of the valve lifter.

2. The guide of claim 1 , wherein the first inwardly curved surface comprises at least two inwardly-oriented curves.

3. The guide of claim 1 , further comprising a platform disposed in the conduit substantially radially with respect to an axial aspect of the conduit.

4. The guide of claim 3 , wherein the platform comprises one or more holes, and wherein one of the one or more holes is capable of facilitating a push rod that engages the valve lifter.

5. The guide of claim 1 , further comprising a plurality of ribs disposed in the base opposite to the conduit.

6. The guide of claim 1 comprising at least two conduits, both extending in one direction from the base.

7. The guide of claim 1 , wherein the conduit has a continuously curving inner surface.

8. The guide of claim 1 , further comprising at least one assembly structure capable of engaging the valve lifter during assembly into an engine.

9. The guide of claim 1 , wherein the first inwardly-curved surface comprises a first contact site and a second contact site and the second inwardly-curved surface comprises a third contact site, such that the third contact site is not directly opposite to the first contact site and the third contact site is not directly opposite to the second contact site.

10. A valve lifter guide comprising:

a base;

a first conduit extending from the base, wherein the first conduit has a first inwardly curved surface opposite from a second inwardly curved surface, wherein the first inwardly curved surface engages a first surface of a valve lifter while the second inwardly curved surface engages a second surface of the valve lifter, which second surface is substantially parallel to the first surface, while preventing rotation of the valve lifter.

11. The guide of claim 10 , wherein the first inwardly curved surface comprises at least two inwardly-oriented curved surfaces.

12. The guide of claim 10 , further comprising a platform disposed in the first conduit substantially radially with respect to an axial aspect of the conduit.

13. The guide of claim 12 , wherein the platform comprises a plurality of holes, and wherein one of the holes is capable of facilitating a push rod that engages the valve lifter.

14. The guide of claim 10 , further comprising a plurality of ribs disposed in the base opposite to the first conduit.

15. The guide of claim 10 , further comprising a second conduit extending in the same direction from the base as the first conduit extends from the base.

16. The guide of claim 10 , further comprising a second base having at least two conduits extending from the second base in the same direction from the base as the first conduit extends from the base.

17. The guide of claim 10 , wherein the first conduit has a continuously curving inner surface.

18. The guide of claim 10 , wherein the first conduit has a substantially curved outer surface.

19. The guide of claim 10 , further comprising at least one assembly structure capable of engaging the valve lifter during assembly into an engine.

20. A valve lifter guide comprising:

a base;

at least one conduit extending from the base, wherein the conduit comprises a first side having a first inwardly curved surface and a second side having a second inwardly curved surface and a third inwardly curved surface, wherein the first side of the conduit is opposed to the second side of the conduit, such that the conduit engages a first surface of a valve lifter with the first inwardly curved surface and a second surface of the valve lifter with the second inwardly curved surface and third inwardly curved surface, while preventing rotation of the valve lifter.
