Abstract: A suction muffler for a reciprocating compressor comprises a first housing portion and a second hosing portion. The first housing portion comprising a first inlet opening, and a second inlet opening. The second housing portion comprises a blocking member configured to block one of a first refrigerant flow path from the first inlet opening to a suction muffler outlet and a second refrigerant flow path from the second inlet opening to the suction muffler outlet. The blocking member can be provided in different configurations by a selection of the second housing portion or by configuring the relative arrangement of the first housing portion and the second housing portion.

Abstract: A hermetic compressor is disclosed. The hermetic compressor comprises compressing unit and an electromotive unit. The compressing unit comprises: a cylinder block having a compression chamber; cylinder head having a discharge chamber which is controllably couplable to the compression chamber; a discharge muffler body portion and a discharge muffler cover which form a discharge muffler chamber coupled to the discharge chamber; a piston configured to compress a refrigerant in the compression chamber; and a main frame having a least one mounting leg. The electromotive unit comprises: a stator; a rotor; and a crankshaft coupled to the rotor. The electromotive unit is configured such that rotary motion of the rotor relative to the stator causes rotation of the crankshaft which drives the piston to compress the refrigerant in the compression chamber.
