Abstract

COMPRESSOR LINEAR. A presente invenção descreve um compressor linear, que pode, rapidamente, superar a carga e aperfeiçoar a eficiência de compressão, por sincronização de uma freqüência operacional de um motor linear, com uma freqüência natural de um elemento móvel variada pela carga, e variação de um curso do elemento móvel de acordo com a carga. O compressor linear inclui: um elemento fixo tendo dentro um espaço de compressão; um elemento móvel reciprocado linearmente no elemento fixo na direção axial, para compressão dos refrigerantes sugados para o espaço de compressão; uma ou mais molas instaladas para suportar elasticamente o elemento móvel na direção de movimento do elemento móvel, cujas constantes de mola são variadas pela carga; e um motor linear instalado para ser conectado ao elemento móvel, para reciprocar linearmente o elemento móvel na direção axial, e variar um curso do elemento móvel, de acordo com uma força de refrigeração predeterminada, de modo que o elemento móvel possa ser reciprocado linearmente para atingir um centro morto de topo.
