ABSTRACT:
An improved oil damped piston for use in internal combustion engines, pumps, compressors, or the like. The piston includes a generally cylindrical piston body having a crown and a depending skirt. A pair of spaced bands of polytetrafluoroethylene are carried by the skirt and each has a surface radially outwardly of the skirt. Each of the band surfaces includes a configuration defining a pumping surface for directing lubricant on a cylinder wall into the space between the band. The oil in the space damps side to side movement of the piston within its cylinder.
