Reciprocating Compressor

A reciprocating compressor comprising:

• a motor having a rotating shaft;
• a low-pressure compressor unit having a low-pressure cylinder and a low-pressure piston for compressing air;
• and
• a high-pressure compressor unit having a high-pressure cylinder and a high-pressure piston for further compressing the air compressed in the low-pressure compressor unit,
• the low-pressure piston and the high-pressure piston each including:
• an eccentric portion for performing eccentric motion with rotation of the rotating shaft of the motor;
• a connecting rod extending from the eccentric portion;
• and a piston body provided on a leading end of the connecting rod,
• wherein, when an eccentric amount of the eccentric portion of the low-pressure piston with respect to the rotating shaft of motor is represented by r1 and an eccentric amount of the eccentric portion of the high-pressure piston with respect to the rotating shaft of motor is represented by r2, the low- and high-pressure pistons are formed in such a manner that r1>r2 is established.
