Claim 5

A coupler as in claim 2, wherein said valve means includes activator means for opening said valve means when said activator means is moved, said activator means being positioned within said first conduit, and said operating means includes urging means for moving said activator means in response to urging by said second conduit on said urging means.

Claim 6

A coupler as in claim 3, wherein said body means includes a body bore extending there through and said urging means includes a plunger positioned to move within said body bore.

Claim 7

A coupler as in claim 4, wherein said coupler fluid flow passage extends through said plunger.

Claim 8

A coupler as in claim 5, further comprising limit means for limiting the movement of said plunger between a first position and a second position.

Claim 9

A coupler as in claim 6, wherein said body means includes a body limit flange extending inwardly within said body fluid flow passage and said plunger includes a first and a second plunger limit flanges extending outwardly from the plunger, said limit means including said body limit flange and said plunger limit flanges, said flanges being positioned and sized to contact one another to limit the movement of the plunger between said first and second positions.

Claim 10

A coupler as in claim 7, wherein said second plunger limit flange is formed by an outwardly extending flare of the wall of plunger at one end of the plunger.

Claim 11

A coupler as in claim 8, wherein said plunger has a first body portion and a second body portion, said first body portion having a first end and a first outer surface, said first plunger limit flange extending outwardly from said first outer surface.

Claim 12

A coupler as in claim 9, wherein said first conduit is a male end and said first end of said body means is a female end, said male end fitting between the inside diameter of the body means and the outside diameter of the plunger.

Claim 13

A coupler as in claim 10, wherein said male end and female ends are cylindrical and threaded.

Claim 14

A fluid conduit coupler comprising: body means for providing a coupler fluid flow passage between a first fluid flow conduit and a second fluid flow conduit; connection means for connecting said body means to said first conduit and to said second conduit to enable fluid flow from said first conduit through said passage to said second conduit; valve means for controlling the flow of fluid through said first conduit; operating means for operating said valve means in response to the connection of said body means to said first and second conduits; said valve means including activator means for opening said valve means when said activator means is moved, said activator means being positioned within said first conduit, and said operating means including urging means for moving said activator means in response to urging by said second conduit on said urging means; said body means including a body bore extending therethrough and said urging means including a plunger positioned to move within said body bore; said coupler fluid flow passage extending through said plunger; limit means for limiting the movement of said plunger between a first position and second position; said body means including a body limit flange extending inwardly within said body fluid flow passage and said plunger including a first and a second plunger limit flanges extending outwardly from the plunger, said limit means including said body limit flange and said plunger limit flanges, said flanges being positioned and sized to contact one another to limit the movement of the plunger between said first and second positions; and said second plunger limit flange being formed by an outwardly extending flare of the wall of said plunger at one end of the plunger.

Claim 15

A fluid conduit coupler comprising: body means for providing a coupler fluid flow passage between a first fluid flow conduit and a second fluid flow conduit; connection means for connecting said body means to said first conduit and to said second conduit to enable fluid flow from said first conduit through said passage to said second conduit; valve means for controlling the flow of fluid through said first conduit; operating means for operating said valve means in response to the connection of said body means to said first and second conduits; said valve means including activator means for opening said valve means when said activator means is moved, said activator means being positioned within said first conduit, and said operating means including urging means for moving said activator means in response to urging by said second conduit on said urging means; said body means including a body bore extending therethrough and said urging means including a plunger positioned to move within said body bore; said coupler fluid flow passage extending through said plunger; limit means for limiting the movement of said plunger between a first position and second position; said body means including a body limit flange extending inwardly within said body fluid flow passage and said plunger including a first and a second plunger limit flanges extending outwardly from the plunger, said limit means including said body limit flange and said plunger limit flanges, said flanges being positioned and sized to contact one another to limit the movement of the plunger between said first and second positions; and said second plunger limit flange being formed by an outwardly extending flare of the wall of said plunger at one end of the plunger.
