  • Discharge line restraint
    Patent number: 5059100
    Abstract: In a hermetic reciprocating compressor, the discharge line functions as a torsion spring in supporting the compressor and motor within the hermetic shell. To prevent excessive deflection of the discharge line while maintaining its torsion spring function, the discharge line is restrained radially and axially while permitting circumferential movement in a helical portion which defines the torsion spring.
