The invention refers to a linear compressor, comprising: a shell (); a cylinder () affixed to the shell () and defining a compression chamber (C); a piston () to be displaced in reciprocating movement in the interior of the compression chamber (C) during the operation of the compressor; a linear electric motor () mounted to the shell (); and an actuating means () operatively coupling the piston () to the linear electric motor (), in order to make the latter displace the piston () in a reciprocating movement in the interior of the compression chamber (C), the actuating means () being coupled to the piston () by an elastic means (), so that the actuating means () and the piston () be displaced in phase opposition during the operation of the compressor.

Linear compressor

A linear motor (), a linear compressor (), a method of controlling a linear compressor (), a cooling system () and a system of controlling a linear compressor () to operate a linear compressor () in resonance in it's the greatest possible efficiency throughout its operation are described. One of the ways of achieving these objectives is by means of a linear compressor () applicable to a cooling system (), the linear compressor () comprising a piston () driven by a linear motor (), the piston () having displacement range controlled by means of a controlled voltage (V), the controlled voltage (V) having a voltage frequency (&#x3c6;) applied to the linear motor () and adjusted by a processing unit (), the range of piston () displacement being dynamically controlled in function of a variable demand of the cooling system (), the linear compressor () having a resonance frequency, the processing unit () adjusting the range of piston () displacement, so that the linear compressor () will be dynamically kept on resonance throughout the variations in demand of the cooling system ().
