    摘要： A piston, piston ring and method of construction thereof is provided. The piston ring is L-shaped, having a first portion configured to extend upwardly from a ring groove of a piston along a top land of the piston and a second portion configured for receipt in the ring groove. The first and second portions of the ring have an enclosed hollow cooling chamber with a cooling medium disposed therein such that the cooling medium is free to flow internally to the piston ring groove and upwardly from the piston ring groove along the top land.

    摘要： A method of and apparatus for producing a hollow ring groove insert for an engine piston, which is inserted by casting near the top of a piston for an engine to constitute a ring groove and a cooling path adjacent to the ring groove. The hollow ring groove insert comprises a formed sheet ring and a ring body having an inner peripheral surface and a piston ring groove. A process for producing the formed sheet ring includes the steps of fitting a sheet ring on a forming die such that the sheet ring covers a forming groove; pressing a forming roll against the sheet ring while rotating the forming die with a floating ring being placed in a movable state where it is radially movable by disengagement from a tapered portion of a centering member, thereby forming circular collars on the sheet ring; pressing a cutting tool against the outer peripheral portions of the circular collars with the floating ring being placed in a state where it is centered and fixed in coincidence with the axial center of the forming die by engagement with the tapered portion of the centering member, thereby turning the outer peripheral portions of the circular collars; and pressing a deburring tool against the outer peripheral portions of the circular collars with the floating ring being placed in the same fixed state, thereby removing burrs from the circular collars.

    摘要： A method of making oil control piston rings having inner diameter and outer diameter central channels with oil drainage slots spaced apart circumferentially communicating the channels, the outer diameter having axially spaced apart scraping beads with radial grooves therein filled with a hard facing metal. The method includes the sequential steps of making a cast unsplit ring, providing axially spaced-apart radial grooves in the outer diameter of the ring, providing an internal inner diameter channel in the said ring, forming blind oil drainage slots in the inner diameter of the ring, spray-coating stacked rings on the outer diameter with a hard-faced coating, machining the stacked rings on the outer diameter to remove the coating except in the area of the outer diameter grooves, forming an outer diameter channel on the ring thereby opening the blind oil slots and forming bevels on the axial ends of the outer diameter of the ring and thereafter splitting the ring axially.

    摘要： PISTON RINGS WITH MULTI-LAYER HARD FACINGS COMPOSED OF AN OUTER BREAK-IN LAYER OF REFRACTORY POROUS SCUFF RESISTING MATERIAL, SUCH AS MOLBYBDENUM, OVER AND BONDED TO A MORE REFRACTORY, LESS POROUS MATERIAL SUCH AS A TUNGSTEN CARBIDE ALLOY WHICH, IN TURN, IS BONDED TO A BASE RING BODY MATERIAL SUCH AS IRON. THE OUTER LAYER, ALTHOUGH REFRACTORY, FUNCTIONS DURING THE ENGINE RUN-IN PERIOD BETTER THAN THE UNDERLYING MATERIAL BECAUSE IT IS SOFTER AND MORE POROUS, AND AS IT WEARS AWAY AND OXIDIZES, A MORE REFRACTORY LESS POROUS UNDERLYING LAYER COMES INTO OPERATION TO INSURE LONG LASTING HIGHLY EFFICIENT SEALING OF THE COMPATABLE RING AND CYLINDER SURFACES FORMED DURING THE BREAK-IN OPERATION OF THE ENGINES.
