Abstract

"COMPRESSOR DE CAPACIDADE VARIáVEL TENDO A ESTRUTURA DE CURSO DO PINO DA MANIVELA AJUSTáVEL". A invenção refere-se a um compressor alternativo de dois estágios. O compressor inclui um bloco com um cilindro único e uma câmara de compressão única associada e pistão único. O compressor adicionalmente inclui um eixo de manivela. O eixo de manivela tem um pino da manivela excêntrico que é operativamente conectado no pistão. Um motor reversível é provido para girar o eixo de manivela em uma direção para frente e em uma direção inversa. Um came excêntrico é montado de modo giratório no pino da manivela excêntrico. O came excêntrico é mantido estacionário com relação ao pino da manivela quando o eixo de manivela está girando na direção para frente. Quando girando na direção para frente, o eixo de manivela conduz o pistão em um percurso completo entre uma posição inferior e uma posição do centro do ponto morto superior. O came excêntrico gira com relação ao pino da manivela quando o eixo de manivela está girando na direção inversa. Quando girando na direção inversa, o eixo de manivela conduz o pistão em um percurso reduzido entre uma posição intermediária e a posição do centro do ponto morto superior.
