초록 ▼

A seal element for installation in an annular groove having a mouth, first and second radial surfaces, and an axial surface therebetween. The seal element has a first radial surface which forms an acute heel angle with the groove first radial surface, and the seal element forms an inner static area adjacent the groove axial surface and first radial surface. Upon installation of a rod and low pressure application, the seal element is compressed into the groove, and the seal element first radial surface is moved into contact with the groove first radial surface. Thus, the seal element prevents contamination from entering into the inner static area. The seal element has first and second angled surfaces forming a high pressure sealing line and third and fourth angled surfaces forming a low pressure sealing line with a stress-relieving radius interconnecting the second and third angled surfaces. When the seal element is positioned in the groove, the angled surfaces face in the direction of and partially protrude through the groove mouth. The stress-relieving radius relieves excessive tensile stress, thereby alleviating the problem of cracking at the sealing face and premature seal failure. Moreover, the stress-relieving radius provides better flexing motion to the low pressure sealing lip, thereby avoiding high compressive stress and reducing the compressive set on the low pressure sealing lip.

A seal element for installation in an annular groove having a mouth, first and second generally parallel radial surfaces, and a generally axial surface interconnecting the first and second radial surfaces, the seal element comprising a generally annular shape, formed of an elastomeric material, and having: a body portion including a generally axial surface for facing the axial surface of the groove and a first generally radial surface for facing the first radial surface of the groove, the first radial surface of the seal element having one end engaging one end of the axial surface of the seal element to form a heel portion, a first generally angled surface having one end engaging the other end of the first radial surface of the seal element, and a second generally angled surface having one end engaging the other end of the first angled surface to form a high pressure sealing line, the first and second angled surfaces for facing in the direction of and partially protruding through the mouth of the groove; the seal element being initially positioned within the groove such that the first radial surface of the seal element forms an initial acute heel angle with respect to the first radial surface of the groove; the heel angle being substantially reduced to a minimal value when an annular opposing surface is positioned across the mouth of the groove to compress the seal element toward the axial surface of the groove and when the compressed seal element is unpressurized, the axial surface of the compressed seal element substantially contacting the axial surface of the groove, the first radial surface of the compressed seal element substantially contacting the first radial surface of the groove, and the high pressure sealing line of the compressed seal element contacting the opposing surface at a first squeeze level; the high pressure sealing line of the compressed seal element contacting the opposing surface at a second squeeze level higher than the first squeeze level when the compressed seal element is pressurized, whereby rocking of the seal element against the first radial surface of the groove during multiple cycles of unpressurization and pressurization is minimized.
