Abstract
This paper describes the results of a search for an optimum profile th at will maximize the dynamic stability of gas lubricated ringless pist ons. Previous work indicated that the common cylindrical piston design is not the best choice for this purpose. Many noncylindrical profiles were investigated for ringless pistons used in helium gas cryocoolers . An improved design was found that considerably extends the range of stable operation of these systems.
