| Number | Title | Issue Date |
| 5328177 | Contaminant resistant piston seal with energized backup scrapers The inner annular surface of a load ring includes a concave contour such that when pressure is applied to the center of the outer surface the elastomer material will flatten out and cause oppositely disposed feet to kick up and radially outwardly and in t... | 07/12/1994 |
| 5275422 | Sealing assembly This invention relates to a fluid sealing mechanism for the inside diameter and or the outside diameter of a piston-cylinder arrangement. This device results in zero seal leakage path with low differential seal pressure required using only one piston ring... | 01/04/1994 |
| 5001965 | Piston and piston ring Pistons and associated piston rings are described for use in internal combustion engines. The piston and piston ring comprise an annular piston ring groove having two radially extending walls and an axially extending wall; a compression ring received in t... | 03/26/1991 |
| 4474106 | Fluidic self adjusting seal assembly A fluidic bearing seal assembly comprised of a plurality of floating back ring seals positioned in a plurality of annular grooves in a piston with at least one free-floating sealing wedge fitted to the outer peripheral edge of each backing ring for slidi... | 10/02/1984 |
| 4214762 | Rolled metal piston ring A rolled steel oil control piston ring for internal combustion engines is of generally U-shaped cross section with a pair of opposed rigid sidewalls projecting inwardly of the ring from a central peripheral wall thereof. A pair of flat-faced solid scraper... | 07/29/1980 |
| 4101140 | Peripherally grooved seal A composite seal for use between a movable element and a static element in a fluid pressure system where pressures vary on opposite sides of the seal. The seal comprises a fluoronated hydrocarbon sealing ring with a finely grooved sealing surface and an e... | 07/18/1978 |
| 4067584 | Guiding and sealing arrangements for pistons, piston rods and the like A guide ring having a seating surface of `U`-shaped cross-section. A plurality of the guide rings may be carried by a piston, piston rod or the like in abutting relation to provide a continuous imperforate surface, or axially spaced from one another with ... | 01/10/1978 |
| 4032159 | Interference compression seal An interference compression seal comprising a delta-shaped seal of relatively soft elastomeric material adapted to be placed in a groove between relatively moving machine parts with the apex of the delta directed radially outwardly creating a line seal an... | 06/28/1977 |
| 3999767 | Piston ring system A multiple element seal ring system comprising a pair of pressure non-deformable split rings and a deformable expander ring adapted to be received in a groove. The split rings are provided with relatively narrow inner surfaces spaced from the groove botto... | 12/28/1976 |
