Abstract
Abstract The present invention includes a valved magnetic coupling of a quick-disconnect type. The coupling includes first and second body members adapted to matingly engage with one another, a permanent magnet for inducing a primary magnetic flux path through the first and second body members when in a coupled position, thereby magnetically holding the body members in locked engagement with each other, and manually operable shunt means for diverting the primary magnetic flux path, thereby diminishing the magnitude of the magnetic force holding the body members in locked engagement.

Claim 2
Dependent Claim
240 words
Coupling apparatus comprising a first body member, a second body member adapted to cooperatively engage said first body member, means for inducing a primary magnetic flux path through said first and second body members, thereby holding said body members in engagement with each other with a force, and shunt means for diverting said primary magnetic flux path, thereby diminishing the magnitude of said force wherein said first body member comprises a first outer annular portion extending substantially coaxially with respect to a first axis and defining a first bearing surface; a first inner portion spaced from said first outer annular portion and extending substantially coaxially with respect to said first axis between a first forward end and a first rearward end, said first inner portion defining a first opening extending therethrough and further including a first valve seat communicating with said firsT opening, first rearward internal threads communicating with the first opening, first forward external threads, and an internal groove disposed forward of said first valve seat; a first juncture portion integral with both the first rearward end of said first inner portion and said first outer portion and extending transversely with respect to said first axis; and a seal ring disposed within said groove, said means for inducing a primary magnetic flux path including a permanent magnetic contact with said first body member, and said shunt means including a movable ring encircling a portion of said first body member.
Claim 3
Dependent Claim
129 words
Coupling apparatus according to claim 1, wherein said second body member comprises a second outer annular portion extending substantially coaxially with respect to a second axis, and defining a second bearing surface; a second inner portion spaced from said second outer annular portion and extending substantially coaxially with respect to said second axis between a second forward end and a second rearward end, said second inner portion defining a second opening extending therethrough and further including a second valve seat communicating with said second opening, second rearward internal threads communicating with the second opening, and a hollow protruding forward member integral with said second forward end adapted to matingly enter said first forward end and engage said seal ring, said first and second axes substantially coinciding with one another.
Claim 4
Dependent Claim
100 words
Coupling apparatus according to claim 2, further comprising a first fitting threadedly engaging said first rearward internal threads and being formed with a first hole extending longitudinally therethrough, said first fitting including and a first main portion defining a plurality of first apertures communicating with both said first hole and the exterior of said first cylindrical extension, a first cylindrical extension formed with a first bore which forms a portion of said first hole, said first cylindrical extension being integral with and extending from said first main portion into said first opening, said first hole communicating with said first opening.
Claim 5
Dependent Claim
99 words
Coupling apparatus according to claim 3, further comprising a second fitting threadedly engaging said second rearward internal threads and being formed with a second hole extending longitudinally therethrough, said second fitting including a second main portion defining a plurality of second apertures communicating with both said second hole and the exterior of said second cylindrical extension, and a second cylindrical extension formed with a second bore which forms a portion of said second hole, said second cylindrical extension being integral and extending from said second main portion into said second opening, said second hole communicating with said second opening.
Claim 6
Dependent Claim
206 words
Coupling apparatus according to claim 4, further comprising first and second valve member assemblies, said first valve member assembly being movable within said first opening and comprising a first valve stem having a first forward shaft and a first rearward shaft each integral with a first central grooved portion, said first rearward shaft extending into said first bore of said first extension; said first forward shaft extending within said first opening toward said second body member, a first valve member mounted on said first central grooved portion and adapted to sealably engage said first valve seat, and a first spring urging said first valve member toward said first valve seat; said second valve member assembly being movable within said second opening and comprising a second valve stem having a second forward shaft and a second rearward shaft each integral with a second central grooved portion, said second rearward shaft extending into said second bore of said second extension, said second forward shaft extending within said second opening toward said first body member, a second valve member mounted on said second central grooved portion and adapted to sealably engage saiD second valve seat, and a second spring urging said second valve member toward said second valve seat.
Claim 7
Dependent Claim
52 words
Coupling apparatus according to claim 5, further comprising a spacer ring in contact with said permanent magnet, and a threaded member threadedly engaging said first forward external threads for retaining said permanent magnet between and in contact with said spacer ring and said first outer annular portion of said first body member.
Claim 8
Dependent Claim
81 words
Coupling apparatus, according to claim 6, wherein said shunt means includes a movable ring formed with an inwardly turned flange portion having a flange bearing surface, and a cylindrical inner wall extending substantially coaxially with respect to said first axis, said coupling apparatus further comprising a shunt spring engaging said flange bearing surface at one end thereof and said bearing surface of said first outer annular portion, thereby urging said shunt ring away from said permanent magnet to an inactive position.
Claim 9
Dependent Claim
86 words
Coupling apparatus according to claim 7, wherein said shunt ring is movable manually from said inactive position against the force of said shunt spring to an active position wherein a primary magnetic flux path induced by said permanent magnet extends from one side of said permanent magnet through said spacer ring into said shunt ring, thereafter through a portion of said first outer annular portion and into an opposite side of the permanent magnet, said first and second fittings being adapted to engage fluid carrying conduits.
