Beschreibung
Zusammenfassung:	A fastener driving tool with a working cylinder and a piston, the piston outer surface having a lubricant-saturated foam material that stores and dispenses lubricant into the piston-cylinder wall interface, thereby increasing the performance and lifespan of the tool. Another embodiment discloses a two-part piston in which the bottom portion is made of metal and absorbs the main mechanical loading forces of the piston drive and return strokes, and the top portion is made of a non-metallic material that has surfaces that act as sliding bearings against the inner wall of the cylinder.
