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.
Claims19
A hermetic fluid compressor comprising:
- a hermetic shell having a fluid port opening through a wall of said shell;
- a discharge member positioned within said shell and separating a suction pressure zone from a discharge pressure zone, said discharge member having a pressure relief passage extending between said discharge pressure zone and said suction pressure zone;
- and
- a pressure relief member located within said suction pressure zone and secured directly to said discharge member by a weld, said pressure relief member being in communication with said pressure relief passage.

A scroll compressor comprising:
- a shell having an inlet port and an outlet port through a wall thereof;
- a first scroll member affixed to said shell and a second scroll member orbiting relative to said first scroll member;
- a plate located within said shell said plate separating a suction pressure zone from a discharge pressure zone, said plate being disposed adjacent to one of said scroll members;
- and
- a pressure relief valve located within said suction pressure zone, said pressure relief valve being welded directly to said plate.
