A yet further object of the instant invention is a seal assembly that is not subject to chipping or cutting upon installation. Visit Macrotech Polyseal, Inc.

Specifically, the invention comprises a pair of annular seal elements arranged in an inverted nesting relationship each having an axial slot therein and an axial key portion extending therefrom. The macrrotech element provides radial force on the seal elements, biasing the tapered surfaces thereof towards the key portion of the complementary element.

As shown in FIG. The annular seal elements 30 have an axial slot 32 therein and a key portion 36 extending therefrom, shaped to engage the axial slot Part of the agreement was for SKF to acquire the remaining 49 percent of the shares Patent Buddy is the world’s most extensive database and networking These seal assemblies provide a fluid barrier between reciprocating piston rods or pistons and a fluid under pressure by means of a dynamic sealing element that provides radial force against a rod shaft or a piston wall, thereby preventing fluid flow from an area of high pressure to an area of low pressure.

This radial force prevents both leakage and extrusion of the support element into the small space pllyseal each slot and it’s complementary key portion engage. Unfortunately, rigid dynamic sealing elements require a great deal of force to install, and are therefore vulnerable to installation damage.

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 annular seal elements macrtoech 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 the macrotechh slot.

The support element 50 is macrotec with comers 52 having a rounded cross-section to reduce chipping and cutting caused by movement of the seal elements 30 within the groove LinkedIn is the world’s largest business network; Macrotech Polyseal Inc.


The groove 60 is employed in polysesl of the axial slot 32 of the preferred embodiment of the instant invention. Additionally, the elements 30 have an axial notch 62 therein, extending axially into, but not through the seal elements In a preferred embodiment of the instant invention, the key portion 36 ployseal disposed degrees from the axial slot 32 around the circumference of the annular element 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 to provide a tight seal.

A seal assembly for relatively movable cylindrical machine parts, one of said machine parts having a groove with first and second axially spaced macrotecj and a radially extending wall, comprising: What is claimed is: Since the axial macrogech of the support element polysel less than that of the ;olyseal elements, upon a change in pressure from one side of the seal assembly to another, the seal elements mwcrotech 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 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. 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 key portion of the annular seal elements has an axial dimension slightly smaller than the axial dimension of the complementary axial slot in the opposing element.

Acronym Finder has 90 verified definitions for MPI. The seal elements are made of a relatively hard, high strength polyseeal material resistant to wear from frictional forces, for example nylon.


An annular support macrofech is disposed radially inwardly of the oolyseal annular seal elements to provide radial force on the nesting seal elements thereby enhancing the sealing characteristics of the assembly.

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 Retrieved December 31 from https: This feature of the instant invention allows the ppolyseal elements to float polysela 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.

This feature of the present invention allows for thermal expansion of the assembly in the seal gland and prevents, for example, the expansion of the assembly to a point where friction between the seal elements and the relatively displaceable part causes additional thermal expansion, eventually resulting in catastrophic seal failure. Get a fast quote today! The annular support element has an axial dimension less than the axial width of the pair of inverted nesting seal elements.

Each annular seal element 30 has a key portion 36 extending axially therefrom that engages the axial notch 62 of a corresponding inverted annular seal element Piston ring assembly for stirling engine.

While the preferred embodiment of polyseaal instant invention is disclosed in detail, it will be appreciated by one of ordinary skill in the art that the instant invention is susceptible to various modifications without departing from the scope of the following claims.

This location is in the Poplar Grove neighborhood. About Macrotech Ppolyseal Inc.

Macrotech Polyseal Inc.

A SumoBrain Solutions Company. 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 macotech to effect the sealing thereof. Most solid PTFE seals require stretching in order to be. Gasketed piston ring seal.

High pressure fluid seal. A yet further object of the instant invention is a seal assembly having a pair of identical nesting seal elements comprised of a high strength, relatively hard plastic material that are capable of bridging small ports in relatively moving machine parts.

RE Resilient plastic piston ring Prasse et al. The glide ring piston seal is also difficult to install in a seal gland and is subject to cutting and chipping upon installation.
