Swash plate compressor

A swash plate compressor comprising:

• a cylinder block;
• a front housing coupled to the front of the cylinder block and having a crank chamber;
• a rear housing coupled to the rear of the cylinder block and having a suction chamber;
• a drive shaft rotatably supported on the cylinder block;
• a swash plate accommodated in the crank chamber and rotated with the drive shaft;
• a piston reciprocating within a cylinder bore of the cylinder block by the swash plate;
• and
• a valve assembly for communicating and blocking the suction chamber and the cylinder bore,
• wherein the valve assembly comprises either a first valve plate or a second valve plate interposed between the cylinder block and the rear housing and a suction plate provided on the cylinder block side with respect to the first valve plate or the second valve plate,
• wherein the suction plate comprises a first orifice hole communicating with the crank chamber and a variable reed adjusting an opening amount of the first orifice hole,
• wherein the first valve plate comprises a second orifice hole communicating with the suction chamber and a reed groove communicating the first orifice hole and the second orifice hole, wherein the second orifice hole is formed at a position radially spaced from the variable reed,
• wherein the suction plate further comprises a third orifice hole formed at a position radially spaced from the first orifice hole and the variable reed, communicating with the crank chamber and having a fixed opening amount,
• and wherein the first valve plate is replaceable with the second valve plate comprising a fourth orifice hole communicating the third orifice hole and the suction chamber.
