Resonant arrangement for a linear compressor

摘要

A resonant arrangement for a linear compressor, comprising a non-resonant assembly formed by a motor and a cylinder ( 1 ); a resonant assembly formed by a piston ( 2 ) reciprocating inside the cylinder ( 1 ); an actuating means ( 3 ) operatively coupling the piston ( 2 ) to the motor, and at least one spring means presenting an elongated tubular body ( 50 ) which is coaxial to the axis of the piston ( 2 ) and is operatively coupled to the actuating means ( 3 ) and to the non-resonant assembly, said tubular body ( 50 ) having at least part of the extension therof folded in circumferential sectors ( 53 ), each circumferential sector ( 53 ) being elastically deformed in the axial direction upon displacement of the piston ( 2 ).
