A SCROLL COMPRESSOR INCLUDING A DISCHARGE CHECK VALVE ASSEMBLY WITH METAL-TO-METAL SEALING SURFACES

The scroll compressor comprising a compressor shell (2) having a discharge outlet (4), and a discharge check valve assembly (18) including a valve housing (21) arranged at the discharge outlet (4) and provided with a metal valve seat (24), and a valve member (26) movable between a closed position and an open position. The metal valve seat (24) has a frusto-conical or toroidal sealing surface (25) and the valve member (26) has a metal sealing surface (36) being configured to cooperate with the frusto-conical or toroidal sealing surface (25) when the valve member (26) is in the closed position, the metal valve seat (24) and the valve member (26) being configured to define a linear sealing contact between the metal sealing surface (36) of the valve member (26) and the frusto-conical or toroidal sealing surface (25) of the metal valve seat (24). The valve member (26) comprises a valve stem portion (33) and a valve head portion (35) connected to the valve stem portion (33). The valve stem portion (33) includes a stem end portion (41) which is remote from the valve head portion (35). The stem end portion (41) includes a tool fixing member (42) configured to allow temporary fixing of a tooling, adapted to displace the valve member (26) in the open position during assembly process of the scroll compressor (1), to the stem end portion (41).
