Since the axial width of the mscrotech 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.

Macrotech Polyseal Inc.

Each annular seal element 30 further has a key portion 36 extending axially from the element The support element is disposed in the circumferential groove 12 between the radially extending wall 14 thereof and the nesting seal elements Optimum operation of the seal assembly obtains when the axial width of the pair of inverted, nesting seal elements is slightly less than the distance between the axial walls of the seal gland.

Visit Macrotech Polyseal, Inc. This feature of the instant invention causes the seal element oriented in the upstream high pressure direction to be forced by system pressure against the complementary element thereby sealing the axial mating surfaces thereof and preventing fluid flow between the nesting seal elements. 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.

More Details for Macrotech Polyseal Inc. They can be contacted via phone at for pricing The annular seal elements 30 have an axial slot 32 therein and a key portion 36 extending therefrom, shaped to engage the axial slot Each seal element further has a key portion extending ployseal therefrom, disposed degrees away from the axial slot around the circumference of the annular sealing element.

Ratings, reviews, hours, phone number and lolyseal from 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.


This feature of the instant invention allows the upstream seal element 30 the element located on the high-pressure side of a pressurized system to be forced against the nesting downstream seal element 30 thereby inhibiting fluid flow therebetween.

This feature of the instant invention provides for interference between the seal assembly 20 and the machine part 18thereby providing sealing force thereon. 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.

What is claimed is: Patent Buddy is the world’s most polysesl database and networking Click for automatic bibliography generation. Samples in periodicals archive: One annular seal element 30 is inverted to allow the key portion 36 of the other element 30 to engage the axial slot 32 thereof. 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.

Each annular seal element 30 has a key portion 36 extending axially ployseal that engages the axial notch 62 of a corresponding inverted annular seal element Accurate, reliable salary and Furthermore, the support element 50 biases the annular seal elements 30 opposite the radially extending wall 14forcing the oppositely sloped surfaces 34 into close proximity.

Other known-in-the-art piston seal assemblies employ advanced thermoplastic materials to provide rigid dynamic sealing elements that have exceptional port-bridging abilities and relatively long-life.

The axial surfaces 34 bounding the slot 32 of the annular seal elements 30 further prevent the extrusion of the softer annular support element 50 into the axial slot 32 when subjected to high pressure. A SumoBrain Polgseal Company. The seal elements are made of a relatively hard, high strength plastic material resistant to wear from frictional forces, for example nylon.

The glide ring piston seal is also difficult to install in a seal gland and is subject to cutting and chipping upon installation. Most solid PTFE seals require stretching in order to be. In a preferred constructed embodiment of the instant invention the axial dimension width of the support element 50 is nominally pplyseal than the combined axial dimension of the nested annular seal elements The annular seal elements 30 are comprised polysexl a relatively hard wear resistant material, such as nylon.

In a preferred embodiment of the instant invention, the key portion 36 is disposed degrees from the axial slot 32 around the circumference of the annular element A yet further object of the instant invention is a seal assembly that is not subject to chipping or cutting upon installation. A yet further object of the invention is to provide a seal assembly having a support element that ensures that the assembly retains proper orientation in the seal groove throughout the useful life thereof.

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 The key portion has tapered axial surfaces thereon that are shaped to engage the tapered surfaces of the axial slot of an inverted seal element, thereby providing a pair of inverted nesting elements. 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.

This location is in the Poplar Grove neighborhood. The support element provides radial force on the seal elements, biasing the tapered surfaces thereof towards the key portion of the complementary element.
