Assembly for sealing and pressure equalization of a submersible housing

摘要

An assembly for sealing and pressure equalization of a submersible motor housing having an open end includes a formed, sheet metal cup including a cylindrical band portion and a base portion with an aperture therethrough. The assembly further includes an elastomeric diaphragm having a side wall that lies against the band portion of the cup and is adhesively secured thereto. The cup includes latching tabs extending from the band portion of the cup. The tabs snap into recesses fabricated in the end of the housing to hold the cup telescoped within the open end of the housing. The portion of the diaphragm secured to the band portion is sandwiched between the band portion and the housing wall and seals against the housing.
