Abstract
A reinforced elastomeric bag for use within an electric submergible motor protector has a generally cylindrical bag body formed as a single continuous structure, and a plurality of reinforcing ribs longitudinally disposed about an inside surface of the bag body. The reinforcing ribs prevent the bag body from collapsing onto and blocking oil inlet ports within the motor protector.
