Hermetic compressor with an improved cylinder head-suction muffler assembly

A hermetic compressor comprising:

• a hermetic vessel;
• a compression element placed in the hermetic vessel;
• a cylinder block including a cylinder that forms the compression element;
• a valve plate including an intake valve port, the valve plate being disposed on the cylinder at an opening end of the cylinder;
• a cylinder head secured to the valve plate opposite to the cylinder;
• an intake muffler having an outlet positioned in the cylinder head, and further having a discharge orifice located at a distal end of the outlet and opened to the intake valve port;
• a concave chamber provided in the cylinder head;
• a resonance space formed by the concave chamber, an external wall of said outlet of said intake muffler and the valve plate which covers said concave chamber;
• and
• an elongated communicating section for establishing communication between the outlet of said intake muffler and the resonance space, the combination of said resonance space and said elongated communicating section forming a resonance type silencer.
