Cylinder head of hermetic reciprocating compressor

A cylinder head of a hermetic reciprocating compressor, comprising;

• a main base mounted on a head plate of a cylinder of said compressor;
• exhaust means for exhausting a compressed fluid which was compressed in said cylinder, said exhaust means being mounted on said main base;
• suction means for sucking a fluid into the cylinder where the fluid is compressed, said suction means being mounted on the main base so as to be spaced apart from said exhaust means by a predetermined clearance, said suction means comprising a horizontal part communicating with an inner space of the cylinder by means of a suction hole, a vertical part comprising a resonance chamber for reducing noise generated during the suction of the fluid and a suction chamber provided at a lower inside portion of said vertical part of said suction means;
• and
• a suction pipe member for sucking said fluid, said suction member comprising a first pipe member mounted on a casing of the compressor for sucking the fluid into the inside of the casing of the compressor, and a second pipe member disposed inside the casing and mounted on said vertical part of said suction means for guiding a portion of the fluid into the suction chamber, said first pipe member having a diameter larger than a diameter of said second pipe member and being spaced apart from said second pipe member by a predetermined clearance so that the fluid not received by the suction chamber through said second pipe member is circulated in the casing.
