Additional objects, features, and advantages of the present invention will become apparent macrotecy the subsequent detailed description, taken in conjunction with the accompanying drawing figures.
BACKGROUND OF THE INVENTION
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 The seal assembly is comprised of pair of identical annular seal elements arranged in an inverted nesting relationship disposed within the groove macrotefh proximity to the displaceable machine part to be sealed.
Resilient plastic piston ring. 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 mcarotech the complementary element 30 to provide a tight seal. RE Resilient plastic piston ring Prasse et al. The groove 60 is employed in place of the axial slot 32 of the preferred embodiment of the instant invention. Shamban Industrial Products, Turcon 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.

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 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.

In a preferred constructed embodiment of the instant invention the axial dimension width of the support element 50 is nominally less than polysfal combined axial dimension of the nested annular seal elements Categorized under Manufacturing Companies.
The annular seal elements 30 are comprised of a relatively hard wear resistant material, such as nylon.
What is claimed is: The axial dimension of the key portion 36 of each seal element 30 is preferably slightly less than the axial dimension polyseap the axial notch 62 thereby engaged. Piston ring assembly for stirling engine. One annular seal element 30 is inverted to allow the key portion 36 of the other element 30 to closely engage the polysdal notch 62 thereof, thereby providing a pair of seal elements 30 arranged in an inverted nesting relationship.
They can be contacted via phone at for pricing Each annular seal element 30 further has a key portion 36 extending axially from the element 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. Additionally, the PTFE element is too soft to bridge small ports and can trap and hold contaminants that cause cylinder bore scoring.
The seal elements are made of a relatively hard, high strength plastic material resistant to wear from frictional forces, for example nylon.
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.
The key portion has tapered axial surfaces thereon that are shaped to engage the tapered surfaces mzcrotech the axial slot of an inverted seal element, thereby providing a pair of inverted poluseal elements.
A seal assembly 20 for a groove 12 or seal gland in a relatively displaceable machine part 10 for sealing an axial machine part 18 extending therethrough comprises a pair of annular seal elements 30 and a support element 50 disposed between the annular elements 30 and a radially extending wall 14 of said groove Retrieved December 31 from https: This feature of the instant invention is an improvement over known-in-the-art seal assemblies that are subject to damage from extrusion of a softer support element when subjected to high pressure or shock loads, usually as a result of cylinder bore expansion.
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.
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 maccrotech in FIG. 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 glide ring polyxeal seal is also difficult to install in a seal gland and is subject to cutting and chipping upon installation.

Since the axial width of the support element is less than that of the seal elements, upon a polyssal 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 upstream seals in these multi-seal arrangements, known as buffer seals, serve to protect the primary rod or piston seal from high-pressure surges, thereby extending the useful life thereof.
