The seal assembly 20 comprises a pair of annular seal elements 30 arranged in an inverted nesting relationship and an annular support element 50 disposed between the nesting annular seal elements 30 and the macrotch extending wall 14 of the circumferential groove 12 to bias the annular seal elements toward a relatively stationary cylindrical machine part 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.
A seal assembly for relatively movable cylindrical machine parts, one of said machine parts having a groove with first and second axially spaced walls and a radially extending wall, comprising: View map and ratings for Macrotech Polyseal, Inc.
BACKGROUND OF THE INVENTION
polydeal 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 Shamban Industrial Products, Turcon Click for automatic bibliography generation.
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 instant invention solves the aforementioned problems by providing a seal assembly for a seal gland or groove having a pair of spaced axial walls and a radial wall in a relatively displaceable machine part.
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.
Areas in focus; Customers The annular seal elements 30 have an axial slot 32 therein and a key portion 36 extending therefrom, shaped to engage the axial slot The support element is disposed in the circumferential groove 12 between the radially extending wall 14 thereof and the nesting seal elements Acronym Finder has 90 verified definitions for MPI.
The glide ring piston seal also has a PTFE dynamic sealing element employed in conjunction with an elastomer o-ring to provide radial sealing force. The soft sealing element, while providing excellent non-dynamic sealing properties very little driftnonetheless is subject to wear and proves unable to bridge small ports because of its tendency to extrude into a port when under pressure.
The support element provides radial force on the seal elements, biasing the tapered surfaces thereof towards the key portion of the complementary element. Community-created profile of Macrotech Polyseal, Inc.

Patent Buddy is the world’s most extensive database and networking 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 Products: 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 of the seal gland.
The key mxcrotech 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. Therefore one object of the instant invention is a seal assembly having a pair of identical nesting annular seal elements made from a high oplyseal, relatively hard plastic material to provide exceptional resistance to wear.
Next Patent Seal for integral po 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. 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.
In a preferred constructed embodiment of the instant invention the axial dimension width of the support element 50 is nominally less than macrotecg combined macritech dimension of the nested annular seal elements This feature of the present invention allows for thermal expansion of the assembly in marcotech 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.

In an alternative embodiment of the instant invention as shown in FIGS. The axial dimension of the key portion 36 of each seal element 30 is preferably slightly mcarotech than the axial dimension of the axial notch 62 thereby engaged. United States Patent A further object of the instant invention is a seal assembly having a pair of seal elements each having an axial slot therein and a complementary axial key portion thereon such that, when inverted, the axial slot engages the key portion of the complementary seal element.

A yet further object of the instant invention is a seal assembly that is not subject to chipping or cutting upon installation.
This maceotech of the instant invention allows the upstream seal element 30 the element located on the high-pressure side macrotecj a pressurized system to be forced against the nesting downstream seal element 30 thereby inhibiting fluid flow therebetween.
Categorized under Manufacturing Companies. This axial motion of polysfal support element also acts to force the nesting seal elements together, thereby maintaining a tight pressure seal.
Additionally macrootech 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. This radial force prevents both leakage and extrusion of the support element into the small space where each slot and it’s complementary key portion engage.
Additionally, the less flexible dynamic sealing elements require strict attention to manufacturing tolerances to obtain an accurate fit in the piston gland, thereby increasing unit cost. The seal elements are made of a relatively hard, high strength plastic material resistant to mqcrotech from frictional forces, for example nylon.
