The linear compressor comprises a shell () which affixes a cylinder () defining a compression chamber () housing a piston (); a linear electric motor () having a fixed part () and a reciprocating movable part (); an actuating means () driven by the movable part (); an elastic means () coupling the actuating means () to the piston (), so that they are reciprocated in phase opposition. A supporting elastic means () connects the actuating means () to the shell () and presents a radial stiffness for supporting the lateral loads actuating on said movable part () and actuating means (), and for minimizing the axial misalignments between the movable part () and the fixed part () of the linear electric motor (), the supporting elastic means () presenting a minimum axial stiffness for allowing the displacement of both the piston () and the actuating means ().

Linear compressor based on resonant oscillating mechanism

The present invention relates to a resonant mechanism for compressors which comprises a tubular body (1) containing at least two slot sets (12) that delimit an intermediate surface (13) which central portion has substantially ellipsoidal conformation (14) on which it is located a hole (15) through which the resonant spring will be affixed (2); a resounding spring (2) housed within the tubular body (1); at least two fastening sets (3) for fastening the resonant spring (2) to the tubular body (1), and leaf flat springs (4) alternately and successively mounted with spacers (not shown) along with the circular side faces (11) of the tubular body (1). The slot sets (12) have a specific configuration to allow rigidity and flexibility suitable for the mechanism operation in situations where the resulting axial force differs from zero.
