Abstract

"COMPRESSOR ROTATIVO MELHORADO COM UM REVESTIMENTO RASPáVEL". Um compressor rotativo melhorado (11) com um revestimento raspável (61) com um valor de dureza máximo de 2H em uma escala de dureza de lápis. O material de revestimento é uma mistura homogênea ou mistura de preferivelmente uma matriz de resina de polímero epóxi com um lubrificante sólido. O lubrificante sólido preferivelmente é grafite. o revestimento raspável melhorado provê folga essencialmente zero para aumentar a eficiência volumétrica de um compressor rotativo tipo Roots.
