Abstract
A sealed compressor includes a lower end cap with a u-shaped hump extending around its periphery. A weld reinforcement which is preferably a ring is welded between inner and outer legs of the u-shaped hump. The weld reinforcement ring bears a good deal of stress from internal pressures, and results in a more long-lasting housing.
