Abstract

A fluid coupling includes a first coupling member, a second coupling member configured for connection with the first coupling member, and a sleeve disposed at least partially around the first coupling member and/or the second coupling member. In embodiments, the sleeve may include a first flame-retardant layer, a second flame-retardant layer, a third flame-retardant layer, and at least one reinforcement of a non-rubber, rigid material.

First claim

What is claimed is:

1. A fluid coupling, comprising
a first coupling member;
a second coupling member configured for connection with the first coupling member; and
a sleeve disposed at least partially around the first coupling member and/or the second coupling member, the sleeve including at least:
a first flame-retardant layer;
a second flame-retardant layer; and
a first intermediate layer disposed between the first flame-retardant layer and the second flame-retardant layer, wherein the first intermediate layer is configured as a cylindrical mesh including woven wires and one or more apertures between the woven wires.

2. The fluid coupling of claim 1 , wherein one or both of the first flame-retardant layer and the second flame-retardant layer include silicone.

3. The fluid coupling of claim 1 , wherein the first intermediate layer is comprised of metal.

4. The fluid coupling of claim 1 , wherein openings in the cylindrical mesh are configured to receive expanding portions of one or both of the first flame-retardant layer and the second flame-retardant layer.

5. The fluid coupling of claim 1 , wherein at least one of the first flame-retardant layer and the second flame-retardant layer is configured as a plurality of sections.

6. The fluid coupling of claim 1 , wherein the second flame-retardant layer is thicker than each of the first flame-retardant layer and the first intermediate layer.

7. The fluid coupling of claim 6 , wherein the second flame retardant layer is at least three times thicker than the first flame-retardant layer.

8. The fluid coupling of claim 6 , wherein the second flame retardant layer is at least ten times thicker than the first intermediate layer.

9. The fluid couple of claim 1 , further comprising a third flame-retardant layer and a second intermediate layer.
