Abstract
Abstract A flexible linearly expansible expansion joint including a flexible sleeve utilized in the connection of one tubular member to a second tubular member. The flexible sleeve encircles the one tubular member and is attached at one end thereto, the opposed end including an elongated cylindrical portion having a diameter less than the diameter of the second tubular member wherein the elongated cylindrical portion extends into the second tubular member and an O-ring is disposed around the outer surface of the cylindrical portion and fits within an annular area defined by the outer surface of the flexible sleeve and the inner surface of the second tubular member to provide a fluid tight seal between the first and second tubular members.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
A fluid connecting device comprising: a first conduit member having a first open end, a second conduit member having a first open end, said second conduit member having an inner diameter greater than the outer diameter of said first conduit member, said first open end of said first conduit member coaxially extending into said first open end of said second conduit member; a resilient flexible sleeve having a first open end and a second open end and surrounding said first conduit member; said first open end of said sleeve being fixedly attached to said first conduit member in a substantially fluid tight relation; a straight flange end on said flexible sleeve extending inwardly into said second conduit, said straight flange end encircling and being radially spaced from said first open end of said first conduit member, said straight flange end being spaced from said second conduit with sealing means disposed therebetween; and, said resilient flexible sleeve maintaining said sealing means in sealing position between said second conduit member and said flexible sleeve.
Claim 2
Dependent Claim
172 words
A fluid connecting device comprising: a first conduit member having a first open end, a second conduit member having a first open end, said second conduit member having an inner diameter greater than the outer diameter of said first conduit member, said first open end of said first conduit member coaxially extending into said first open end of said second conduit member; a resilient flexible sleeve having a first open end and a second open end and surrounding said first conduit member; said first open end of said sleeve being fixedly attached to said first conduit member in a substantially fluid tight relation; a straight flange end on said flexible sleeve extending inwardly into said second conduit, said straight flange end encircling and being radially spaced from said first open end of said first conduit member, said straight flange end being spaced from said second conduit with sealing means disposed therebetween; and, said resilient flexible sleeve maintaining said sealing means in sealing position between said second conduit member and said flexible sleeve.
Claim 3
Dependent Claim
14 words
The fluid connecting device of claim 1, said flexible sleeve being a corrugated sleeve.
Claim 4
Dependent Claim
37 words
The fluid connecting device of claim 1, said sealing means including a collar with recess means at one end thereof to receive a sealing ring therein, said sealing ring encircling and engaging with said straight flange end.
Claim 5
Dependent Claim
52 words
The fluid connecting device of claim 3, said collar including an elongated cylindrical section at said end opposing said recess means receiving said flexible sleeve, said cylindrical section being received in sealing relation by said second conduit member, said cylindrical section being spaced from said straight flange end defining an annulus therebetween.
Claim 6
Dependent Claim
40 words
The fluid connecting device of claim 1 wherein said flexible sleeve includes a straight flange end defining said first open end, said straight flange end being sandwiched between two ring members, one ring member being mounted onto said first conduit.
