Abstract:
1. A reciprocating compressor comprising: a container having a suction pipe in which gas is sucked; a frame unit having a front frame installed inside the container; a reciprocating motor installed at the frame unit and generating a linear reciprocating driving force; a compression unit installed at the frame unit with a certain distance from the reciprocating motor, receiving the driving force of the reciprocating motor and compressing gas; a spring unit for elastically supporting the linear reciprocating driving force of the reciprocating motor; and a valve unit installed at the compression unit and opening/closing a compression space in which gas is compressed, wherein a piston of the compression unit has a flange portion located between the motor and front frame and connected to a mover of the reciprocating motor, and wherein a distance (k) between a front frame of the frame unit and the flange portion of the piston is smaller than a distance (m) between the reciprocating motor and the flange portion of the piston.
