Abstract

"COMPRESSOR LINEAR". Trata-se de um compressor linear. O compressor linear compreende um cilindro (109) e um pistão (144) movido em vaivém no cilindro (109). à parte posterior do pistão (144) é preso de maneira fixa um primeiro silenciador (160), de modo que o primeiro silenciador (160) seja movido em vaivém juntamente com o pistão (144). No compressor é montado de maneira fixa um segundo silenciador (170), de modo que o volume interno do segundo silenciador (170) varie à medida em que o primeiro silenciador (160) é movido linearmente. O canal de fluxo de fluido (140) do segundo silenciador (170) comunica-se com o canal de fluxo de fluido (140) do primeiro silenciador (160). Os primeiro e segundo silenciadores (160, 170) têm também espaços redutores de ruído definidos neles. De acordo com a presente invenção, a eficácia de introdução do compressor linear é aperfeiçoada, e o ruído gerado em diversas bandas é efetivamente reduzido. Desenho representativo: Figura 3"LINEAR COMPRESSOR". It is a linear compressor. The linear compressor comprises a cylinder (109) and a reciprocating piston (144) in cylinder (109). to the rear of the piston (144) is fixedly secured to a first silencer (160) so that the first silencer (160) is reciprocated with the piston (144). A second silencer (170) is fixedly mounted to the compressor so that the internal volume of the second silencer (170) varies as the first silencer (160) is moved linearly. The fluid flow channel (140) of the second silencer (170) communicates with the fluid flow channel (140) of the first silencer (160). The first and second silencers (160, 170) also have noise reducing spaces defined therein. According to the present invention, the introduction efficiency of the linear compressor is improved, and the noise generated in several bands is effectively reduced.
