Firewall heater line adapter

Claim 2

A flowthrough connector assembly for passing a high heat fluid between first and second reservoirs separated by a wall having an opening therein, comprising in combination an adapter body mountable on said wall and including at least two tubular conduits each defining a central passageway and extending into the opening, a pair of angled elbows each having a first and a second end portion, each elbow being adapted to have its first end portion removably mounted in a respective conduit such that its second end portion is spaced from the adapter and positionable angularly for desired mating, the elbows being independently angularly positionable relative to one another, and retainer means in each said elbow for retaining a fluid conduit in a swivelable sealed connection therewith, each said elbow and fluid conduit being swivelable independently of one another.

Claim 3

The flow through connector assembly as recited in claim 1 wherein said retainer means comprises each said elbow having a shoulder adjacent each of its ends and a tubular polymeric retention clip being received in each said end portion, said clip having a resilient finger for engaging a respective shoulder in the elbow thereby retaining the clip in the elbow and a resilient locking tab for seating engagement behind an annular collar of the fluid conduit to be releasably retained.

Claim 4

The flow through connector assembly as recited in claim 1 wherein said adapter body and conduits are integrally molded of a heat resistant polymer.

Claim 5

The flow through connector assembly as recited in claim 3 wherein the elbows are molded of a heat resistant polymer.

Claim 6

The flow through connector assembly as recited in claim 1 wherein the body member comprises a thin flat plate, and the conduits are sized such that each extends from one side of the plate and through the opening substantially the entire width of the firewall, one said conduit extending from the other side of the plate.

Claim 7

The flow through connector assembly as recited in claim 5 wherein the elbows are identical whereby one said elbow has its second end portion positioned further outwardly from said plate that the other said elbow.

Claim 8

An adapter for coupling fluid conduits, comprising an adapter body including two adjoining conduit receiving passageways the axes of the passageways being generally parallel to one another, a pair of tubular elbows, each elbow having first and second end portions and a central passage extending between its ends for conveying a fluid therebetween, the first and second end portions of each elbow being disposed at an acute angle to one another with the first end portions of the elbows being swivelably releasably mounted in a respective conduit and the second end portions extending outwardly from the adapter body such that rotation of the first end portions angularly change the position of the second end portions for mating with respective fluid conduits, and retainer means in the end portions for swivelably releasably retaining a fluid conduit in the respective elbow end portions.

Claim 9

An adapter for coupling fluid conduits, comprising an adapter body including two adjoining conduit receiving passageways the axes of the passageways being generally parallel to one another, a pair of tubular elbows, each elbow having first and second end portions and a central passage extending between its ends for conveying a fluid therebetween, the first and second end portions of each elbow being disposed at an acute angle to one another with the first end portions of the elbows being swivelably releasably mounted in a respective conduit and the second end portions extending outwardly from the adapter body such that rotation of the first end portions angularly change the position of the second end portions for mating with respective fluid conduits, and retainer means in the end portions for swivelably releasably retaining a fluid conduit in the respective elbow end portions.

Claim 10

Apparatus, mountable in an opening on a wall separating a pair of reservoirs, for passing a fluid from one reservoir to the other reservoir and back to the one reservoir, comprising a pair of couplings each coupling having opposite end portions angled one to other, retention clips releasably mounted in the opposite end portions of said couplings for swivelably, releasably, retaining a respective fluid conduit, a pair of tubular conduits extending into the opening for supporting respective adjacent one end portions of the couplings for rotation, one said tubular conduit being of a length greater than the other said tubular conduit such that the other end portion of said one coupling extends further outwardly from the wall than the other coupling so as to be angularly positionable remote to the wall, each end portion of each coupling receiving and retaining a fluid conduit for communicating fluid from or to said reservoirs, each said fluid conduit when retained in an end portion of said coupling completing a swivelable fluid tight connection.

Claim 11

Apparatus, mountable in an opening on a wall separating a pair of reservoirs, for passing a fluid from one reservoir to the other reservoir and back to the one reservoir, comprising a pair of couplings each coupling having opposite end portions angled one to other, retention clips releasably mounted in the opposite end portions of said couplings for swivelably, releasably, retaining a respective fluid conduit, a pair of tubular conduits extending into the opening for supporting respective adjacent one end portions of the couplings for rotation, one said tubular conduit being of a length greater than the other said tubular conduit such that the other end portion of said one coupling extends further outwardly from the wall than the other coupling so as to be angularly positionable remote to the wall, each end portion of each coupling receiving and retaining a fluid conduit for communicating fluid from or to said reservoirs, each said fluid conduit when retained in an end portion of said coupling completing a swivelable fluid tight connection.
