ABSTRACT:
In a hermetic compressor, a seal extending between a suction port and a second port in fluid communication with an internal chamber disposed adjacent an electric motor. The seal includes a cylindrical tubular member, one end of which slidingly fits within the suction port. A slotted conical flange on the other end of the tubular member fits around the port on the chamber. When a suction line is attached to the suction port with a threaded nut and fitting, it abuts against the projecting end of the tubular member, forcing the cone-shaped flange on the other end of the tubular member to flatten slightly as it seats against the external surface of the chamber. Most of the suction fluid entering the suction port flows through the tubular member into the chamber and through the electric motor to cool it. The compliant flange on the seal allows substantial tolerance in the spacing and angular displacement of the port in the internal chamber relative to the suction port in the shell. This minimizes alignment problems during both compressor assembly and operation.
