A linear compressor is provided in which a driving spring and an elastic supporting member for supporting a compressing mechanism portion are disposed such that a piston and the compressing mechanism portion move in opposite phases such that vibration of a hermetic vessel is canceled out. The linear compressor comprises a hermetic vessel having a compressing mechanism portion and a linear motor therein. The compressing mechanism portion includes a piston-side mechanism and a cylinder-side mechanism, the former includes the piston and the mechanism member which is movable together with the piston, the latter includes the cylinder and the stator which connects with the cylinder. The cylinder-side mechanism member is elastically supported at opposite ends in the hermetic vessel by a first elastic member, and a reciprocating force in the axial direction is given the piston-side mechanism by a second elastic member whose one end is supported by the hermetic vessel.
A linear compressor comprising a hermetic vessel having a compressing mechanism portion and a linear motor therein, wherein said compressing mechanism portion comprises a cylinder and a piston which reciprocates in the cylinder, said linear motor comprises a moving member which provides said piston with reciprocating driving force and a stator which is fixed to said cylinder and which forms a reciprocation path for said moving member, said compressing mechanism portion and said linear motor are classified into a piston-side mechanism member and a cylinder-side mechanism member, said piston-side mechanism member includes said piston and said moving member which is movable together with said piston, said cylinder-side mechanism member includes said cylinder and said stator being connected to said cylinder, said cylinder-side mechanism member is elastically supported at opposite ends in said hermetic vessel by a first elastic means and a reciprocating force in the axial direction is given to said piston-side mechanism member by a second elastic means whose one end is supported by said hermetic vessel.
