Swash plate compressor

A swash plate compressor comprising

• a cylinder block configured to accommodate a piston for compressing a refrigerant;
• a front housing coupled to a front side of the cylinder block and having a crank chamber;
• a rear housing having a suction chamber and a discharge chamber and coupled to a rear side of the cylinder block;
• and
• a gasket inserted into the cylinder block, and a suction reed plate inserted between a valve plate and the cylinder block, the swash plate compressor further comprising:
• a first orifice hole through which the refrigerant in the crank chamber passes;
• a second orifice hole communicating with the suction chamber and configured to discharge the refrigerant passing through the first orifice hole to the suction chamber;
• and
• an intermediate flow path configured to connect the first orifice hole and the second orifice hole;
• and the valve plate inserted between the cylinder block and the rear housing and having a suction chamber pressure-maintaining space connected to the suction chamber and configured to maintain a pressure equal to a pressure in the suction chamber, wherein the valve plate further comprises a first valve plate through hole penetratively formed in the valve plate to connect the suction chamber pressure-maintaining space and the suction chamber;
• and wherein the second orifice hole is formed from a second valve plate through hole penetratively formed in the valve plate and spaced apart from the first valve plate through hole.
