Dry sump oil cooling system
First Claim
1. An oil cooling system for an internal combustion engine, said oil cooling system comprising:
- an oil reservoir having a first end, a second end, a length therebetween, a top and a bottom;
an oil return port defined substantially at said first end adjacent said top of said reservoir and adapted to allow oil to enter said reservoir;
an oil pickup port defined substantially at said first end adjacent said bottom of said reservoir and adapted to allow oil to exit said reservoir; and
a baffle at least partially disposed in said reservoir and at least partially defining an oil passageway such that oil entering said reservoir through said oil return port flows over said baffle in a first direction, and under said baffle in a second direction substantially opposite the first direction, before exiting through said oil pickup port.

Abstract
A dry sump oil cooling system for an internal combustion engine includes an oil pan reservoir, an oil return port, an oil pickup port, and a baffle. The oil pan reservoir has a first end, a second end, a length therebetween, a top and a bottom. Both the oil return port and the oil pickup port are defined at the first end of the reservoir. The oil return port is located adjacent the top of the reservoir while the oil pickup port is located adjacent the bottom of the reservoir. The baffle is coupled to the reservoir between the top and the bottom or free-standing within the reservoir to divide the reservoir into a top chamber and a bottom chamber. The baffle at least partially defines an oil passageway between the top chamber and the bottom chamber at the second end such that most of the oil flows substantially across the length of the oil pan reservoir twice before being returned to the engine by the oil pickup port.

13. An oil cooling system for an internal combustion engine, said oil cooling system comprising:
-
an oil reservoir having a first end, a second end, a length therebetween, a top and a bottom; an oil return port defined substantially at said first end adjacent said top of said reservoir and adapted to allow oil to enter said reservoir; an oil pickup port defined substantially at said first end adjacent said bottom of said reservoir and adapted to allow oil to exit said reservoir; and a baffle having a top wall, at least one side wall depending from said top wall, and a cavity at least partially defined by said top wall and said at least one side wall, said baffle being at least partially disposed in said reservoir and at least partially defining an oil passageway substantially at said second end such that oil entering said reservoir through said oil return port flows through said oil passageway before exiting through said oil pickup port. - View Dependent Claims (14, 15, 16)

17. An oil reservoir baffle comprising:
-
a top wall; a side wall; an end wall; and an open end opposite said end wall; whereby said baffle is positionable in an oil pan having a length to cause oil entering said oil pan to flow at least said length of said oil pan prior to exiting said oil pan. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
