ABSTRACT:
A compressor has an hermetic shell within which is located an internal pressure relief (IPR) valve. The valve is resistance welded directly to a separation plate in a scroll compressor or directly to the outside wall of the discharge muffler in a piston/cylinder compressor. The direct welding of the IPR valve eliminates unnecessary components and lowers the manufacturing costs of the compressor.
