This axial motion of the support element also acts to force the nesting seal elements together, thereby maintaining a tight pressure seal. Gasketed piston ring polyseao. 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 18 to effect the sealing thereof. Acronym Finder has 90 verified definitions for MPI.

This feature of the instant invention allows the seal elements to float in the gland while maintaining each element in close proximity to it’s complement such that a reverse in pressure direction rapidly forces the elements together to maintain a leak-proof seal.

Resilient plastic piston ring.

Search Expert Search Quick Search. The support element provides radial force on the seal elements, biasing the tapered surfaces thereof towards the key portion of the complementary mcrotech.

One annular seal element 30 is inverted to allow the key portion 36 of the polysezl element 30 to closely engage the axial notch 62 thereof, thereby providing a pair of seal elements 30 arranged in an inverted nesting relationship.

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 The annular seal elements 30 have an axial slot 32 therein and a key portion 36 extending therefrom, shaped to engage the axial slot A yet further object of the instant invention is a seal assembly that is not subject to chipping or cutting upon installation.


This location is in the Poplar Grove neighborhood.

Additionally, the PTFE element is too soft to bridge small ports and can trap and hold contaminants that cause cylinder bore scoring.

Hydraulic fluid sealing applications often require robust double-acting seal assemblies for pistons or rods, or any axially displaceable machine part moveable through an annular passage in a complementary part. 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 ployseal the seal gland.

polysela The seal elements are made of a relatively hard, high strength plastic material resistant to wear from frictional forces, for example nylon. Each seal element 30 is further provided with a flat axial surface 42 extending around the circumference thereof that is forced into close proximity with the corresponding axial surface 42 of the complementary element 30 polyseak provide a tight seal. What is claimed is: United States Patent Get all the facts!

The instant invention relates generally to machinery seals disposed in grooves or seal glands to provide a fluid seal between relatively moving machinery parts. Additionally the axial dimension of the key portion 36 of each seal element 30 is preferably slightly less than the axial dimension of the axial slot 32 thereby engaged, as best seen in FIG.


Shamban Industrial Products, Turcon The annular seal elements 30 are comprised of a relatively hard wear resistant material, such as nylon. They can be contacted via phone at for pricing In a preferred embodiment of the instant invention the axial dimension width of the pair of nested annular seal elements 30 is nominally less than the axial width of the circumferential groove Additional objects, features, and advantages of the present invention will become apparent from the subsequent detailed description, taken in conjunction with the accompanying drawing figures.

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.

Accurate, reliable salary and In an alternative embodiment of the instant invention as shown in FIGS. 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. The annular seal elements each have an axial slot therein, bounded by a pair of beveled end surfaces tapered from the exterior radius thereof to the interior radius thereof that prevent extrusion of the resilient support element into pilyseal axial slot.

The PTFE element reduces the tendency of the seal to wear over time but is expensive and difficult to install because it must be stretched into place.

Additionally, the elements 30 have an axial notch 62 therein, extending axially into, but not through the seal elements
