The support element 50 biases the nesting seal elements 30 radially toward the relatively stationary machine part 18 thereby forcing the seal elements against the part macrotecu to effect the sealing thereof.

Macrotech Polyseal Inc Products: A further object of the instant invention is a seal assembly having a pair of seal elements each having an axial slot therein and a complementary axial key portion thereon such that, when inverted, the axial slot engages the key portion of the complementary seal element.

Most solid PTFE seals require stretching in order to be.

Shamban Industrial Products, Turcon Accordingly, the pair of oppositely sloped surfaces 34 of each annular seal element 30 in this embodiment of the instant invention is disposed radially between the male key portion 36 of the complementary nesting seal element 30 and the annular support element Accurate, reliable salary and Unfortunately, rigid dynamic sealing elements require a great deal of force to install, and are therefore macroteech to installation damage.

Additionally the axial dimension of the key portion 36 of each seal element 30 is preferably macroteech less than the axial dimension of the axial slot 32 thereby engaged, as best seen in FIG.

Click for automatic bibliography generation. The support element is disposed in the circumferential groove 12 between the radially extending wall 14 thereof and the nesting seal elements Therefore one object of the instant invention is a seal assembly having a pair of identical nesting annular seal elements made from a high strength, relatively hard plastic material to provide exceptional resistance to wear. Polyaeal annular seal elements 30 have an axial slot 32 therein and a key portion 36 extending therefrom, shaped to engage the axial slot About Macrotech Polyseal Inc.

The seal elements are made of a relatively hard, high strength plastic material resistant to wear from frictional forces, for example nylon. Additionally, this feature of the instant invention allows the nested annular seal elements 30 to shift against the downstream axial wall 16 of the circumferential groove 12 when system pressure shifts from one side of the seal assembly 20 to the other, prior to the support element 50 shifting to the downstream axial wall The seal assembly is comprised of pair of identical annular seal elements arranged in an inverted nesting relationship disposed within the groove in proximity to the displaceable machine part to be sealed.

This embodiment of the instant invention provides superior retention of the the seal elements 30 in the groove 12 during installation of the assembly 20or when an irregularity, for example a port, in the relatively stationary machine part 18 is encountered by the seal assembly 20 as the relatively displaceable machine part 10 moves.

High pressure fluid seal. As shown in FIG. United States Patent Resilient plastic piston ring. What does MPI stand for? The annular support element has an axial dimension less than the axial width of the pair of inverted nesting seal elements.

The axial surfaces macortech bounding the slot 32 of one element 30 are engaged by the beveled surfaces 40 of the key portion 36 of the other element, thereby providing a pair of seal elements 30 polyswal in an inverted nesting relationship. Since the axial width of the support element is less than that of the seal elements, upon a change in pressure from one side of the seal assembly to another, the seal elements will be forced to the downstream axial wall of the seal gland in advance of the support element, thereby preventing the more resilient support element from extruding out of the seal gland.

The annular support element 50 is preferably comprised of a resilient, flexible, elastic material such as polyurethane or any of various elastomeric compounds suitable for use in sealing environments, as well known to one of ordinary skill in the art.

In a preferred constructed embodiment of the instant invention the axial dimension width of the support element 50 is nominally less than the combined axial dimension of the nested annular seal elements Salt Lake City, UT.

Get company and product information. The seal assembly 20 comprises a pair of annular seal elements 30 arranged in an inverted nesting relationship and an annular support element 50 disposed between the nesting annular seal elements 30 and the radially extending wall 14 of the circumferential groove 12 to bias the annular seal elements toward a relatively stationary cylindrical machine part The support element 50 is provided with comers 52 having a rounded cross-section to reduce chipping and cutting caused by movement of the seal elements 30 within the groove Additionally, the PTFE element is too soft to bridge small ports and can trap and hold contaminants that cause cylinder bore scoring.

The tapered surfaces of the axial slot in the seal elements closely engage the key portion of the complementary element, thereby prohibiting the more resilient support element from being forced into the axial slot macrotedh under pressure.

The seal elements 30 are arranged in an inverted nesting relationship to provide superior sealing characteristics when biased toward the machine part 18 by said support element
