Resonance device for linear compressor

Abstract

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 thereof folded in circumferential sectors (53), each circumferential sector (53) being elastically deformed in the axial direction upon displacement of the piston (2).

Description

technical field [0001] The present invention generally relates to a structural arrangement for a resonant compressor, of the type driven by a linear motor, used in refrigeration systems, the arrangement having a piston reciprocating within a cylinder. Background technique [0002] In a reciprocating compressor driven by a linear motor, the operations of air suction and air compression are performed by the reciprocating axial movement of the piston in the cylinder, which is closed by a cylinder head and installed in a sealed housing, and a control is provided in the cylinder head The intake and exhaust valves through which gas enters and exits the cylinder. The piston is driven by a drive mechanism that supports a magnetic element driven by a linear motor fixed to the compressor housing. [0003] In some constructions, the piston is mounted against a resonant spring mechanism in the form of a leaf spring assembly, which is fixed to the hermetic casing of the compressor in or...

AI Technical Summary

Problems solved by technology

[0008] This construction also has some disadvantages such as the need to have a larger size compressor to accommodate the use of a pair of coil springs which cannot be properly secured to withstand tension

[0009] Furthermore, the coil spring has the characteristics of generating eccentric force and shear force on its mounting surface, generating force on the bearing of the compressor piston, generating noise and wear, and reducing the life of the compressor
