Patent ID: 7162936

Claim:
A system for providing a flow of cooling medium between cooling medium lines ( 30 ′, 32 ′) of an engine ( 26 ) and a hydrodynamic retarder housing ( 12 ) wherein the hydrodynamic retarder housing ( 12 ) is located at a first end of a transmission housing ( 4 ) and a second end of the transmission housing ( 4 ) is mounted to the engine by a clutch bell housing ( 6 ) mating with the engine ( 26 ), comprising: first coupling flanges ( 16 , 18 ) are mounted to the clutch bell housing ( 6 ) at a junction between the clutch bell housing ( 6 ) and the engine ( 26 ), each first coupling flange ( 16 , 18 ) being connected to a corresponding cooling medium tube ( 20 , 22 ) for conveying cooling medium to the retarder housing ( 12 ), second coupling flanges ( 30 , 32 ) connected to engine cooling medium lines ( 30 ′, 32 ′) of the engine ( 26 ) and mounted to the engine ( 26 ) at the junction between the clutch bell housing ( 6 ) and the engine ( 26 ) so that corresponding ones of the first and second coupling flanges come into connecting mating relationships to connect each cooling medium tube ( 20 , 22 ) to a corresponding one of the engine cooling medium lines ( 30 ′, 32 ′).
