Abstract

593,669. Piston rings. FLOWER, A. June 21, 1945, No. 15829. [Class 122 (i)] In a piston for a fluid pressure engine, at least two L-sectioned coacting rings 15 are located (e.g. by casting) in the metal of the piston 12 by inwardly extending radial portions 15b and their peripheral portions extend outside the metal of the piston in the operative direction to engage one another with a portion 16 of the radially outer surface o' each exposed for separately engaging the wall of the coacting cylinder and these portions are flared slight y to form a diameter slightly in excess of that of the co-operating cylinder 1. A lug 18 on one ring nay space the rings apart during the casting operation and the rings be separated solely by an L-sectioned, heat-conductive packing ring 35 nested in a stepped portion of the inner ring.
