Abstract

"COMPRESSOR TIPO BAILARINA". Tendo um eixo (16) e uma válvula rotativa (37), que são construídos integralmente, são feitos de metal à base de ferro enquanto que um bloco de cilindros (12) é feito de metal à base de alumínio. Uma bucha (43) forma uma superfície deslizante entre o bloco de cilindros (12) e a válvula rotativa (37), quando o eixo (16) e válvula rotativa (37) giram conjuntamente. A bucha (43) apresenta um coeficiente de expansão térmica mais próximo ao do eixo (16) e da válvula rotativa (37) do que ao do bloco de cilindros (12). Essa estrutura impede um aumento no espaço entre o cárter e a válvula rotativa, devido ao aumento da temperatura no momento em que o eixo gira em alta velocidade e impede o escape de gás e a redução na vedação."BALLARINE COMPRESSOR". Having a shaft (16) and a rotary valve (37), which are integrally constructed, are made of iron-based metal while a cylinder block (12) is made of aluminum-based metal. A bushing (43) forms a sliding surface between the cylinder block (12) and the rotary valve (37) when the shaft (16) and rotary valve (37) rotate together. The bushing (43) has a coefficient of thermal expansion closer to the shaft (16) and rotary valve (37) than to the cylinder block (12). This structure prevents an increase in the space between the crankcase and the rotary valve due to the increase in temperature as the shaft rotates at high speed and prevents gas leakage and reduced seal.
