A hermetic compressor having improved configuration of a cylinder head to more efficiently attenuate noise and vibration of refrigerant discharge. The hermetic compressor includes a cylinder block having a compression chamber in which a piston rectilinearly reciprocates, and a cylinder head coupled with the cylinder block to hermetically seal the compression chamber. The cylinder head has a suction chamber and discharge chamber, which are partitioned from each other. The suction chamber serves to guide a refrigerant to be introduced into the compression chamber, and the discharge chamber serves to guide the refrigerant, which was delivered from the compression chamber after being compressed in the compression chamber, to the outside. The hermetic compressor also includes a valve device interposed between the cylinder block and the cylinder head, to control movement of the refrigerant from the suction chamber to the compression chamber or from the compression chamber to the discharge chamber. A partition member having a bore is detachably mounted in the cylinder head, to divide the discharge chamber into two parts, in order to integrally define a Helmholtz resonator in the discharge chamber.
