Title: HIGH PRESSURE DYNAMIC SEALING DEVICE
Abstract:
A sealing assembly includes a first machine component having a seal groove defined by radially oriented jacket support and energizer positioning walls and an energizer compressing wall that faces axially toward a second machine component. A seal located within the seal groove has an energizer element and a telescoping jacket. The jacket has a first leg portion having a jacket sealing surface facing toward the second machine component and an energizer contacting wall facing toward the energizer element. The energizer element is compressed between the energizer contacting and energizer compressing walls and loads the jacket sealing surface against the second machine component. A jacket second leg portion extends generally axially and has an energizer supporting wall facing toward the energizer element and a supported wall facing radially and adjoining the jacket support wall. The second leg portion is interposed between the energizer element and the jacket support wall.
