Linear compressor

A linear compressor comprising a shell which affixes, internally, a cylinder defining a compression chamber in whose interior is provided a piston;

• a linear electric motor having a fixed part internally affixed to the shell and a movable part reciprocating in relation to the fixed part;
• an actuating means affixed to the movable part of the linear electric motor, to be driven by said movable part in a reciprocating movement;
• a first cylindrical helical spring coupling the actuating means to the piston, so that said first cylindrical helical spring, said actuating means, and said piston are displaced, as a resonant movable assembly, in a reciprocating movement, during operation of the compressor, wherein the compressor comprises a supporting elastic means is defined by at least one second cylindrical helical spring, which is coaxial to an axis of the fixed part of the linear electric motor and having an end coupled to the actuating means and an opposite end coupled to the shell such that the second cylindrical helical spring connects the actuating means to the shell, wherein a portion of the first cylindrical helical spring is disposed within an inner space of the second cylindrical helical spring, the second cylindrical helical spring providing a radial rigidity capable of supporting lateral loads actuating on the assembly defined by the movable part of the linear electric motor and by the actuating means, so as to minimize axial misalignments between said movable and fixed parts of the linear electric motor, resulting from effects of said lateral loads, said supporting elastic means presenting providing a minimum axial rigidity, so as to allow a desired displacement of the piston and the actuating means.
