Reinforced sealing rings

A device comprising:

• a cylinder comprising a bore, wherein the bore comprises a low-pressure region and a high-pressure region;
• a piston comprising a ring groove, wherein the piston is configured to translate along an axis of the bore;
• and
• a sealing ring assembly arranged in the ring groove, the sealing ring assembly comprising:
• at least one ring segment of a first tensile strength configured to seal between the low-pressure region and the high-pressure region;
• and
• at least one metal reinforcement layer bonded to the at least one ring segment along an interface, wherein:
• shear forces between the at least one ring segment and the at least one metal reinforcement layer are transmitted, and
• based on being bonded, the at least one metal reinforcement layer provides a compressive preload onto the at least one ring segment along the interface causing the sealing ring assembly to be of a second tensile strength greater than the first tensile strength, wherein the at least one metal reinforcement layer exerts a radially inward force on the at least one ring segment at the interface.

A sealing ring assembly comprising:

• at least one ring segment of a first tensile strength, comprising a first end and a second end;
• and
• at least one wire reinforcement engaged with the at least one ring segment at the first end and at the second end, such that:
• the at least one ring segment is in compression and the at least one wire reinforcement is in tension along the at least one wire reinforcement between the first end and the second end, wherein the at least one wire reinforcement exerts a radially inward force on the at least one ring segment, and
• the sealing ring assembly is of a second tensile strength greater than the first tensile strength.
