Lubrication cooler system and method

摘要

A lubrication cooler system comprises a first flow path (18) connecting a lubrication inlet (40) and a lubrication outlet (42). A second flow path (16) is provided in parallel with the first flow path, connecting the lubrication inlet and outlet, and further comprising a lubrication cooler (22) therebetween. A means (38) for blocking all or a part of the first or second flow path is also provided. The blocking means provides a way of adjusting the lubricant flow in the first or second flow paths, to selectively balance the external lubricant cooling and internal lubrication requirements. The system may be used in automotive applications e.g. lubricating/cooling vehicle transmissions.
