Flutter free piston ring assembly

A piston and ring assembly operative within a cylindrical bore wall to retain fluids to one side, the piston having a side wall for movement along the cylindrical wall, comprising:

• (a) the piston having one or more spaced grooves in said side wall, each groove defining a pair of interior groove surfaces spaced apart a uniform distance;
• (b) at least one sealing element presenting a pair of opposed surfaces operating between and along said pair of groove surfaces, said at least one sealing element being capable of engaging said cylindrical wall, the spacing between said opposed surfaces of said at least one sealing element and said pair of interior surfaces of said groove being no greater than ten microns;
• and
• (c) a continuous solid film lubricant mixture coating said groove surfaces and at least the opposed surfaces of said at least one sealing element, whereby surface adhesion of said fluid present in said spacing inhibiting migration of such fluid through said spacing and flutter of said at least one sealing element in said spacing being essentially eliminated.
