Abstract
A method of assembling a reciprocating piston hermetic compressor including a two piece suction valve capable of being deburred by abrasive material. The reexpansion volume between the valve leaf and valve spacer is reduced to a minimum since the clearance between the valve leaf and valve spacer is reduced by the fabrication method. The valve leaf may be made of a different material than the valve spacer using the same or a different stamping tool.
