  • Flexible bellows piston seal
    Patent number: 4268042
    Abstract: Means and method are provided for utilizing a piston and cylinder combination eliminating the usual sealing and oil rings and their accompanying friction and replacing them with ball bearings which in the principal embodiment are captured in splitring cages which are snapped into the existing grooves of the piston. Having thus lost the sealing ability of the piston, an accordion-type diaphram is utilized in the top of the cylinder to define the compression or combustion chamber.
