Ellipsoid Roller Bearing Piston Ring

US Patent:
7284526, Oct 23, 2007
Filed:
Jun 5, 2006
Appl. No.:
11/422140
Inventors:
Allan R. Williams - Edmonds WA, US
International Classification:
F16J 1/02
US Classification:
1231936, 92178
Abstract:
An improved piston ring suitable for use in an internal combustion engine is disclosed comprising a plurality of races sized to receive elongate rollers disposed around the circumference thereof. The elongate rollers may be shaped as a prolate ellipsoid or other rounded shape. The piston ring may seat within a groove in fluid communication with an oil channel extending through a piston rod and opening into a rod bearing connecting the piston rod to a crankshaft. A crankshaft has a corresponding oil channel therewith and has an opening positioned to periodically align with the opening in the rod bearing when rotated. Oil is pumped into the oil channel in the crankshaft to force oil over the piston rings. Drain apertures may be formed in another groove formed in the piston to conduct oil away from the piston.
