Abstract
The present disclosure provides a sealing ring assembly having a first ring and a second ring, configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. Accordingly, the sealing ring assembly includes a high-pressure boundary and a low-pressure boundary. Each ring may be segmented, and the first and second rings interface along a surface. Along the surface at the interface, a groove open to the lower pressure region aids in pressure locking the sealing ring assembly. A pocket in the second ring allows for high pressure gas to aid in balancing radial forces on the sealing ring assembly. As the sealing ring wears, the first and second rings remain engaged with one another.
