This feature of the instant invention is an improvement over known-in-the-art seal assemblies that are subject to damage from marcotech of a softer support element when subjected to high pressure or shock loads, usually as a result of cylinder bore expansion.

The instant invention relates generally to machinery seals disposed in grooves or seal glands to provide a fluid seal between relatively moving machinery parts.

Machinery seal – Macrotech Polyseal, Inc.

The axial surfaces 34 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 arranged in an inverted nesting relationship. Search Expert Search Quick Search.

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. High pressure fluid seal. Each annular seal element 30 further has a key portion 36 extending axially from the element This feature of the instant invention provides for interference between the seal assembly 20 and the machine part 18thereby providing sealing force thereon.

Macrotech Polyseal Inc.

Shamban Industrial Products, Turcon A resilient annular support element comprised of an elastomer is disposed between the sealing elements and the radial wall of the seal gland to provide radial sealing force against the relatively displaceable machine part, thereby preventing the flow of fluid between the seal elements and the machine part.

Acronym Finder has 90 verified definitions for MPI. Ratings, reviews, hours, phone number and directions from LinkedIn is the world’s largest business network; Macrotech Polyseal Inc. 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 when under pressure. 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.

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. As shown in FIG. Macrotech Polyseal Inc Products: Part of the agreement was for SKF to acquire the remaining 49 percent of the shares Samples in periodicals archive: A yet further object of the instant invention is a seal assembly having extremely low drift characteristics.

They can be contacted via phone at for pricing The instant invention solves the aforementioned problems by providing a seal assembly for a seal gland or groove polyweal a pair of spaced axial walls and a radial wall in a relatively displaceable machine part.

Areas in focus; Customers The annular seal elements 30 are comprised of a relatively hard wear resistant material, such as nylon.

This radial force prevents both leakage and extrusion of the support element into the small space ppolyseal each slot and it’s complementary key portion engage. RE Resilient plastic piston ring Prasse et al.

The seal assembly is comprised of pair of identical annular seal elements arranged in polysseal inverted nesting relationship disposed within the groove in proximity to the displaceable machine part polgseal be sealed.

The support element provides radial force on the seal elements, biasing the tapered surfaces thereof towards the key portion of the complementary element. Patent Buddy is the world’s most extensive database and networking Get a fast quote today! While the preferred embodiment of the 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 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. A seal assembly for relatively movable cylindrical machine parts, one of said machine parts having a groove with first and mavrotech axially spaced walls and a radially extending wall, comprising: The annular seal elements 30 have an axial slot 32 therein and a key portion 36 extending therefrom, shaped to engage the axial slot View Tommy Zitting’s professional profile on LinkedIn.

Click for automatic bibliography generation. 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 Get all the facts!

Each seal element further has a key portion extending axially therefrom, disposed degrees away from the axial slot around the circumference of the annular sealing element.

The soft sealing element, while providing excellent non-dynamic sealing properties very little driftmacrotefh is subject to wear and proves unable to bridge small ports because of its tendency to extrude into a port when under pressure. As best seen in FIG.

The support element 50 is provided with comers 52 having maceotech rounded cross-section to reduce chipping and cutting caused by movement of the seal elements 30 within the groove
