Abstract: The present disclosure provides a sealing ring assembly having a ring and one or more gap cover elements, configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. The ring may be segmented, and the gap cover elements may engage with interfaces between the ring segments. The gap cover elements are configured to move radially outward and wear as the ring wears. The gap cover elements may include, for example, wedge-shaped features that engage with corresponding wedge recesses in the interfaces. The sealing ring assembly may include a high-pressure boundary and a low-pressure boundary. As the sealing ring wears, the gap cover elements stay engaged with the interfaces, so that ring gaps do not form on the low pressure boundary.

Abstract: An improved bearing or bushing body extraction from a stuffing box using jack screws is provided. The bearing or bushing seal body includes at least one jack screw on each half of a split body. The jack screw passes axially through the sidewall of the body to the inner flange of the stuffing box and turning the jack screw against the inner flange to lift the body from the stuffing box. A single inner threaded or double threaded insert with a reverse outer thread and standard inner thread is inserted into the bottom wall of the body so that the body may be installed flush against the inner flange. By turning the jack screw through the insert and against the flange, the seal body is pushed out rather than pulled.
