  • Cooling system for I.C.E. valve seat inserts
    Patent number: 4941436
    Abstract: Valve seat inserts of a four-cycle internal-combustion engine are cooled by the lubricating oil of the oil circulating system. An oil duct extending in the camshaft housing is bored in such a manner that the lubricating oil flows from the oil duct into a ring duct surrounding the valve seat inserts. By means of a projection which closes off the ring duct, a forced flow around the valve seat insert is achieved before the lubricating oil flows out of the ring duct through an opening located close to the lubricating oil inlet. From the ring duct the lubricating oil flows through a discharge pipe to the camshaft where it is sprayed on the cams.
