Abstract: A device for detecting a piston position of a linear compressor is provided to measure change of microwaves in a whole compression space instead of recognizing phenomenon at a top dead point to find out a position of a piston from a relationship with a resonance frequency of refrigerant. A device for detecting a piston position of a linear compressor includes a microwave probe(44) extended into a compression space(P) of the linear compressor, in which refrigerant is inhaled and compressed, for carrying out incident waves or reflected waves. A signal generating part(40) generates an excitation source. A detecting part such as a crystal detector(46) measures energy or power of the reflected waves. A frequency reading part(50) reads frequency characteristics according to the detected energy or power. A control part(60) calculates or recognizes a position of a piston(6) of the linear compressor from the read frequency characteristics. A directional coupler(42) is additionally mounted between the microwave probe, the signal generator and the detecting part for transmitting the excitation source or the reflected waves. An amplification part(48) is additionally mounted between the detecting part and the frequency reading part.

Abstract: A magnetic force leakage prevention structure of a linear compressor is provided to prevent collision between a shell and a discharge valve assembly and prevent magnetic force leakage by allowing a discharge cap to be formed of non-magnetic material. A magnetic force leakage prevention structure of a linear compressor comprises a shell(130), structure and a discharge cap. The shell is closed space. The structure comprises a fixing member, an operation member and a linear motor(110) in the inside of the shell, and linearly reciprocates the operation member inside the fixing member by electromagnetic force of the linear motor. The discharge cap of non-magnetic material is fixed to one end of the operation member so as to be communicated with compressed space formed between the operation members, and forms predetermined discharge space.
