A valve assembly of hermetic compressor is disclosed, in which a valve insertion groove (44) and (45) are formed. The valve insertion groove (44) includes a suction opening (42) on a head (40) provided between a cylinder (5) and a head cover (10), and the valve insertion groove (45) includes a discharge opening (43). An insertion type suction valve (50) and an insertion type discharge valve (60) are connected to said valve insertion grooves (44) and (45) respectively by spot welding. Accordingly, the valve assembly of hermetic compressor can make the valve smaller and simpler, so that reduced fabricating cost and improved productivity can be obtained. Also, at the same time dead volume can be reduced, thereby improving the compression efficiency.
