Abstract
Abstract The disclosure pertains to the combination of a seal element and a spacer member for being interposed between a pair of parts which confine a fluid passage. The seal element sealingly engages the parts and sealing effect is enhanced by a overpressure inside the seal element. The spacer member surrounds the seal element on the outside and limits the compression of the seal element when the parts are connected together and is formed of a porous powdered metal material so as to drain off from around the outside of the seal element any fluid escaping from the inside of the seal element to the outside thereof.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
137 words
In a seal arrangement for sealing between a pair of adjacent parts which define a passage for confining fluid under pressure when the parts are assembled; a seal element between and in sealing engagement with said parts and exposed on the inside to the fluid under pressure which is confined by said parts, said seal element in relaxed condition being axially longer than the space therefore between said parts when said parts are assembled and the sealing effect of said seal element being enhanced by an over pressure on the inside thereof, and a sUbstantially rigid spacer member arranged between said parts concentrically with said seal element, said parts and spacer member being clamped together in face to face relation to form a unit, said spacer member being porous so as to permit fluid to pass therethrough.
Claim 2
Dependent Claim
137 words
In a seal arrangement for sealing between a pair of adjacent parts which define a passage for confining fluid under pressure when the parts are assembled; a seal element between and in sealing engagement with said parts and exposed on the inside to the fluid under pressure which is confined by said parts, said seal element in relaxed condition being axially longer than the space therefore between said parts when said parts are assembled and the sealing effect of said seal element being enhanced by an over pressure on the inside thereof, and a sUbstantially rigid spacer member arranged between said parts concentrically with said seal element, said parts and spacer member being clamped together in face to face relation to form a unit, said spacer member being porous so as to permit fluid to pass therethrough.
Claim 3
Dependent Claim
20 words
A seal arrangement according to claim 1, in which said spacer member is formed of compacted and sintered powdered metal.
Claim 4
Dependent Claim
30 words
A seal arrangement according to claim 2, in which said spacer member has up to 20 percent of the volume thereof as open interconnected porosity through which fluid can pass.
Claim 5
Dependent Claim
60 words
A seal arrangement according to claim 2, in which said seal element is in the form of an endless metal strip having at least one convolution therein when viewed in cross section, said seal element tending to expand in the axial direction to enhance the sealing effect thereof upon the occurrence of overpressure on the inside of the seal element.
Claim 6
Dependent Claim
47 words
A seal arrangement according to claim 4, in which said seal element has legs on the opposite axial ends of the seal element directed toward the inside of the seal element and having the radially inner tip ends thereof in sealing engagement with the respective said parts.
Claim 7
Dependent Claim
31 words
A seal arrangement according to claim 5, in which the said tip ends of said legs present sharp corners to the respective said parts so as to penetrate into said parts.
Claim 8
Dependent Claim
27 words
A seal arrangement according to claim 5, in which the said tip ends of said legs are provided with a deformable coating for engagement with said parts.
Claim 9
Dependent Claim
32 words
A seal arrangement according to claim 2, in which said spacer member has vibration damping characteristics and thereby inhibits the transmission of vibrations from one of said parts to the other thereof.
Claim 10
Dependent Claim
18 words
A seal arrangement according to claim 2, in which said seal element is substantially U-shaped in cross section.
Claim 11
Dependent Claim
19 words
A seal arrangement according to claim 2, in which said seal element is substantially Sigma shaped in cross section.
Claim 12
Dependent Claim
39 words
A seal arrangement according to claim 2, in which said spacer member surrounds said seal element on the radially outer side thereof and engages the radially outer periphery of said seal element and thereby controls the radial expansion thereof.
Claim 13
Dependent Claim
22 words
A seal arrangement according to claim 2, in which said spacer member is on the radially inner side of said seal element.
Claim 14
Dependent Claim
40 words
A seal arrangement according to claim 12, in which a further member is provided on the radially outer side of said seal element and engages the radially outer periphery of said seal element and thereby controls the radial expansion thereof.
Claim 15
Dependent Claim
25 words
A seal arrangement according to claim 13, which includes clamping bolts interconnecting said parts and disposed on the radially outer side of said seal element.
