Abstract:
A piston support structure for a reciprocating compressor comprising:a reciprocating motor; a front frame, a central frame and a rear frame; a piston receiving a linear, reciprocating driving force generated by the reciprocating motor, said piston being in a linear reciprocating motion within a compression space formed in a cylinder; a resonant spring unit having a bent spring supporter positioned between the front frame and the central frame and operatively connected to said reciprocating motor, a plurality of first resonant springs and a plurality of second resonant springs, said first and said second resonant springs being positioned on a first side and a second side of the bent spring supporter, respectively, wherein the first resonant springs and the second resonant springs elastically support the linear reciprocating motion of the piston, and spring constants of the second resonant springs is larger than spring constants of the first resonant springs, said first resonant springs being positioned on a compression space side of the cylinder, and said second resonant springs being positioned opposite to said first resonant springs.
