  • Lubricating and sealing system for internal combustion engines
    Patent number: 3948241
    Abstract: A lubrication and sealing system for the cylinder head of an internal combustion engine having a sleeve valve mounted for rotation therein, said sleeve valve having intake slots therethrough which register periodically, as the valve rotates, with air intake ports in the cylinder to permit air to enter the cylinder. The sleeve valve is provided with one or more helically shaped sealing rings carried in the wall of the valve facing the wall of the cylinder, which said rings, as the valve rotates, sweep the wall of the cylinder to circulate lubricant oil within the clearance space between the valve and the cylinder to thereby lubricate and seal the clearance space. The circulation of lubricant also has a beneficial cooling effect.
