Abstract

An engine is provided with a cylinder block and a ladderframe having a portion of an oil conduit and a deflector. The engine has a metal-to-metal seal positioned between the ladderframe and block to circumferentially surround the oil conduit, and has a gasket seal positioned between the ladderframe and block to be outboard and spaced apart from the oil conduit. The deflector is positioned between the metal-to-metal seal and the gasket seal. An engine component is provided with a member having a deflector and forming an oil conduit. The deflector has an arcuate deflector surface following an outer wall of the oil conduit to redirect oil escaping the oil conduit. A ladderframe is configured to provide a deflection surface, with the deflection surface positioned to guide high pressure oil away from adjacent RTV seals.

First claim

What is claimed is:

1. An engine comprising:
a cylinder block defining a portion of an oil conduit intersecting a lower surface of the block;
a ladderframe having an upper surface intersecting another portion of the oil conduit and a deflector adjacent to the another portion of the oil conduit;
a metal-to-metal seal positioned between the upper surface of the ladderframe and the lower surface of the block to circumferentially surround the oil conduit; and
a gasket seal positioned between the upper and lower surfaces to be outboard and spaced apart from the oil conduit;
wherein the deflector is positioned between the metal-to-metal seal and the gasket seal.

2. The engine of claim 1 wherein the deflector extends from the ladderframe towards the cylinder block.

3. The engine of claim 1 wherein the deflector has a top surface that is co-planar with the upper surface of the ladderframe.

4. The engine of claim 1 wherein the deflector has a top surface that is offset from the upper surface of the ladderframe such that the lower surface of the block is positioned between the upper surface of the ladderframe and the top surface of the deflector.

5. The engine of claim 1 wherein the deflector is arcuate.

6. The engine of claim 1 wherein the deflector conforms to and follows an outer surface of the another portion of the oil conduit.

7. The engine of claim 6 wherein a radius of an inner edge of the deflector is greater than a radius of the outer surface of the another portion of the oil conduit.

8. The engine of claim 1 wherein the gasket seal comprises a room temperature vulcanizing (RTV) material.

9. The engine of claim 1 wherein the deflector is defined by a deflector surface and an elongate support.

10. The engine of claim 9 wherein the elongate support extends orthogonally from the deflector surface towards the ladderframe.

11. The engine of claim 9 wherein the deflector surface is formed by an arcuately shaped surface.

12. The engine of claim 11 wherein the deflector surface has a constant width along a length of the deflector with opposite end regions of the deflector surface being tapered.

13. The engine of claim 1 wherein the ladderframe defines the another portion of the oil conduit as a tubular structure having an inner wall and an outer wall extending transversely to the upper surface, and a component mating face extending between and connecting the inner and outer walls, the inner wall defining an oil passage therein.

14. The engine of claim 13 wherein the deflector has an arcuate deflector surface following the outer wall of the another portion of the oil conduit, the deflector positioned adjacent to and radially outboard of the outer surface to redirect oil escaping the oil conduit and flowing towards the gasket seal.

15. The engine of claim 13 wherein the block defines the portion of the oil conduit as another tubular structure having another inner wall and another outer wall extending transversely to the lower surface, and another component mating face extending between and connecting the another inner and outer walls, the inner wall defining the oil passage therein;
wherein the inner wall of the ladder frame and the another inner wall of the block are aligned with one another;
wherein the outer wall of the ladder frame and the another outer wall of the block are aligned with one another; and
wherein the component mating face of the ladderframe and the another component mating face of the block are each in contact with the metal-to-metal seal.

16. The engine of claim 1 wherein the deflector extends transversely to the upper surface of the ladderframe from an elongate support to a top face to provide an arcuate deflector surface.

17. The engine of claim 16 wherein a radius of the deflector surface is greater than a radius of the outer wall of the another portion of the oil conduit such that the deflector partially surrounds the oil conduit.

18. The engine of claim 1 wherein the deflector has first and second ends connected by an inner concave wall, the inner concave wall extending outwardly from the upper surface of the ladderframe to a top surface of the defector.

19. The engine of claim 18 wherein the deflector has an outer convex wall extending between and connecting the first and second ends, the outer convex wall extending outwardly from the upper surface of the ladderframe to the top surface of the deflector.

20. The engine of claim 1 wherein the ladderframe member defines a groove sized to receive the gasket seal, the deflector surface positioned between the oil conduit and the groove and shaped to redirect oil escaping the oil conduit and flowing towards the seal.
