Abstract:
Piston rings are disclosed that relate to seal performance in piston containing machines such as piston driven engines. The piston rings may include a piston ring contact side for contact with a cylinder wall in which the piston ring contact side has multiple cavities configured on alternating edges of the piston ring contact side. Certain examples of these piston rings have cavities with an average depth that is less than 1/300 th  of the piston ring width and which collectively occupy a cavity area percentage of the piston ring contact side that is between 20% and 30% of the total area of the piston ring contact side.

Claim (Index 5):
The piston ring of  claim 1  wherein the first cavity is trapezoidal.
