Abstract: The piston structure comprises a body having a substantial number of circumferential grooves each receiving a piston ring, the radially outer portions of said rings extending vertically in spaced relation to the piston to comprise, in effect, a substantially continuous cylinder wall-engaging sleeve, thus reducing contact of the piston itself with the cylinder wall, groove engaging portions of the rings spaced from the bottoms of the grooves to receive oil for cushioning the rings and permitting expansion of the piston.
