Patent ID: 6865334

Claim:
A module oil seal assembly for use in an optical fiber hydrophone module, the module comprising an optical hydrophone assembly, a woven fiber protection cable assembly proximate to an end of the hydrophone assembly, an intermodule bulkhead coupling, and a clevis mounted to the intermodule bulkhead coupling, the hydrophone assembly comprising a plurality of mandrels helically wrapped with optical fiber and connected in linear relation, the woven fiber protection cable assembly comprising an elastic woven strap with one looped end, the looped end of the woven fiber protection cable assembly disposed at least partially within the clevis and towards the bulkhead coupling, the module oil seal assembly comprising: a module oil seal, having a cylindrical wall with one end substantially closed and the other end open, the wall defining a cavity, the open end having an annular face plate extending outwardly from the periphery of the wall, the face plate surface distal from the closed end of the module oil seal being a face seal; one orifice through the substantially closed end of the module oil seal, the orifice adapted to receive a check valve; an opening through the substantially closed end for receiving optical fibers; means for sealing in proximate registration with the face seal; and wherein the module oil seal except for the face plate is reciprocally mounted within the clevis, and the face plate is reciprocally mounted within the bulkhead coupling such that the face seal abuts an adjacent surface of the coupling to make a seal.
