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 component comprising a member having a deflector and forming an oil conduit intersecting an upper surface, the oil conduit defined by a tubular structure with an inner wall and an outer wall extending transversely to the upper surface, a component mating face extending between and connecting the inner and outer walls the inner wall defining an oil passage therein, the deflector having an arcuate deflector surface following the outer wall of the oil conduit and positioned adjacent to and radially outboard of the outer wall to redirect oil escaping the oil conduit and flowing towards a groove in an outer edge region of the member, the groove sized to receive a room temperature vulcanizing seal.

2. The engine component 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 member to a top surface of the defector.

3. The engine component of claim 2 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 member to the top surface of the deflector.

4. The engine component of claim 2 wherein the top surface of the deflector is co-planar with the component mating face of the oil conduit.

5. The engine component of claim 2 wherein the top surface of the deflector is parallel to the component mating face of the oil conduit and offset therefrom.

6. The engine component of claim 1 wherein the deflector is positioned between the outer wall of the oil conduit and the groove.

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

8. The engine component of claim 7 wherein a radius of the deflector surface is greater than a radius of the outer wall of the oil conduit such that the deflector partially surrounds the oil conduit.

9. The engine component of claim 1 wherein the component is a ladderframe and the upper surface is shaped to cooperate with a lower surface of a cylinder block.

10. A ladderframe member having an upper surface shaped to cooperate with a lower surface of a cylinder block, the ladderframe member defining a tubular oil conduit having an inner wall and an outer wall, the inner and outer walls extending transversely to and outwardly from the upper surface, the inner wall defining an oil passage therein and arranged concentrically with the outer wall, the upper surface of the ladderframe member extending between and connecting the inner and outer walls of the tubular oil conduit, the ladderframe member defining a deflector having an arcuate deflector surface, the arcuate deflector surface having an inner concave wall curved to follow the outer wall of the tubular oil conduit, the arcuate deflector surface positioned adjacent to and radially outboard of the outer wall of the tubular oil conduit, the ladderframe member defining a groove sized to receive a room temperature vulcanizing 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.
