Abstract
Abstract Means for sealing joints subjected to extremely high fluid pressures in the order of 70 thousand pounds per square inch wherein an elastic member is provided which is disposed between and initially subjected to moderate mechanical pressure by the components of the joint to be sealed and subsequently subjected to extremely high fluid pressure whereby the elastic member is deformed between the components of the joint so as to seal the joint against leakage.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
223 words
In a nozzle assembly, the combination including a tubular member defining an internal fluid supply passageway, a body defining a stepped bore communicating with an outlet and providing a radially disposed shoulder in said body, a retaining member disposed in said bore and having a radially extending surface confrontable with an end surface on said tubular member, a nozzle carried by said retaining member and defining an orifice communicating with both said passageway and said outlet, an annular elastic sealing member disposed between and engageable with said retaining member and said tubular member, and means for mechanically joining said tubular member and said body whereby said confrontable surfaces on said tubular member and said retaining member engage said sealing member, said sealing member having at least a portion thereof exposed to said passageway to be subjected to high pressure fluid therein and said sealing member defining a space permitting deformation of said sealing member by such high pressure fluid, said sealing member being adapted to deform into said space upon the application of high fluid pressure to provide a fluid tight seal between said surfaces, and said sealing member being located to cause its said seal between said surfaces to prevent fluid passage between said retaining member and said radially disposed shoulder in said body and between said tubular member and said body.
Claim 2
Dependent Claim
223 words
In a nozzle assembly, the combination including a tubular member defining an internal fluid supply passageway, a body defining a stepped bore communicating with an outlet and providing a radially disposed shoulder in said body, a retaining member disposed in said bore and having a radially extending surface confrontable with an end surface on said tubular member, a nozzle carried by said retaining member and defining an orifice communicating with both said passageway and said outlet, an annular elastic sealing member disposed between and engageable with said retaining member and said tubular member, and means for mechanically joining said tubular member and said body whereby said confrontable surfaces on said tubular member and said retaining member engage said sealing member, said sealing member having at least a portion thereof exposed to said passageway to be subjected to high pressure fluid therein and said sealing member defining a space permitting deformation of said sealing member by such high pressure fluid, said sealing member being adapted to deform into said space upon the application of high fluid pressure to provide a fluid tight seal between said surfaces, and said sealing member being located to cause its said seal between said surfaces to prevent fluid passage between said retaining member and said radially disposed shoulder in said body and between said tubular member and said body.
Claim 3
Dependent Claim
28 words
A nozzle assembly according to claim 1, wherein said space is defined by said confrontable surfaces, said sealing member and the wall of said bore in said body.
Claim 4
Dependent Claim
32 words
A nozzle assembly according to claim 2, wherein said sealing member is exposed to said passageway along its inner periphery, and said space is adjacent the outer periphery of said sealing member.
Claim 5
Dependent Claim
18 words
A nozzle assembly according to claim 2, wherein said sealing member is in the form of an O-ring.
Claim 6
Dependent Claim
45 words
A nozzle assembly according to claim 2, wherein an end portion of said tubular member adjacent said body defines a semi-toroidal groove communicating with said internal passageway, said sealing member being in the form of an O-ring having a portion thereof disposed in said groove.
Claim 7
Dependent Claim
204 words
In a nozzle assembly, the combination including a tubular member defining an internal fluid supply passageway, a holder having a body defining a stepped bore communicating with an outlet and providing a radially disposed shoulder in said body, a retaining member disposed in said bore and having a radially extending surface substantially coplanar with said shoulder, a nozzle carried by said retaining member and defining an orifice communicating with both said passageway and said outlet, an annular elastic sealing member disposed between said tubular member and said body and engageable with said shoulder and said radially extending surface, said sealing member having at least a portion thereof exposed to said passageway, and means for mechanically joining said tubular member and said body whereby said tubular member, said shoulder and said radially extending surface engage said sealing member, said sealing member being adapted to deform upon the application of fluid pressure to effect a fluid tight seal between said tubular member, sAid shoulder and said radially extending surface, and said sealing member being located to cause its said fluid tight seal to prevent fluid passage between said retaining member and said radially disposed shoulder in said body and between said tubular member and said body.
Claim 8
Dependent Claim
204 words
In a nozzle assembly, the combination including a tubular member defining an internal fluid supply passageway, a holder having a body defining a stepped bore communicating with an outlet and providing a radially disposed shoulder in said body, a retaining member disposed in said bore and having a radially extending surface substantially coplanar with said shoulder, a nozzle carried by said retaining member and defining an orifice communicating with both said passageway and said outlet, an annular elastic sealing member disposed between said tubular member and said body and engageable with said shoulder and said radially extending surface, said sealing member having at least a portion thereof exposed to said passageway, and means for mechanically joining said tubular member and said body whereby said tubular member, said shoulder and said radially extending surface engage said sealing member, said sealing member being adapted to deform upon the application of fluid pressure to effect a fluid tight seal between said tubular member, sAid shoulder and said radially extending surface, and said sealing member being located to cause its said fluid tight seal to prevent fluid passage between said retaining member and said radially disposed shoulder in said body and between said tubular member and said body.
Claim 9
Dependent Claim
32 words
A nozzle assembly according to claim 6, wherein said sealing member is exposed to said passageway along its inner periphery, and said space is adjacent the outer periphery of said sealing member.
Claim 10
Dependent Claim
24 words
A nozzle assembly according to claim 6, wherein said means for joining said tubular member and said body together includes a mating threaded connection.
Claim 11
Dependent Claim
19 words
A nozzle assembly according to claim 8, wherein said annular sealing member is in the form of an O-ring.
Claim 12
Dependent Claim
30 words
A nozzle assembly according to claim 9, wherein said retaining member is disposed in said bore in radially spaced relationship with respect to surfaces of said body defining said bore.
Claim 13
Dependent Claim
47 words
A nozzle assembly according to claim 6, wherein an end portion of said tubular member is provided with an external thread adapted to mate with an internal thread provided in the bore of said body to effect the mechanical joining of said tubular member and said body.
