Abstract

756,150. Piston packing. WELLWORTHY. Ltd. March 8, 1954 [March 6, 1953], No. 6271/53. Class 122(1) A piston ring 1 has an annular insert 2, of softer material than that of the ring, received in a groove around the periphery of the ring, the external surface of the insert being substantially flush with the periphery of the ring except for a reduced part 5 of the periphery which extends. from one end of the ring to the insert, and the ring being formed with a recess 6 on. the inner corner at the opposite end from that of the reduced part 5. The recess 6 causes the split-ring 1 to assume a dished form upon being closed into the bore of the cylinder 4 so that the ring rides on the insert 2 during suction strokes. During compression strokes the ring is expanded by the compressed fluid and its entire outer periphery then contacts the bore. The ring may be of iron or steel and the inserts 2, 3 of bronze, the latter being rolled into grooves in the ring and. machined substantially flush with the ring.
