Abstract

''ELEMENTO ESPIRAL PARA UM COMPRESSOR ESPIRAL E COMPRESSOR ESPIRAL'', incluindo um elemento espiral fixo (12) e um elemento espiral orbital (14). Cada um dos elementos espirais tem uma superfície planar (18, 24) estendendo-se da capa no elemento até a borda períferica do elemento. Uma área de alívio (56) é formada em cada uma dos elementos espirais através da superfície planar para mover o ponto do pivó efetivo da força de pressão intermediária reagindo contra a força tangencial do gás radialmente para dentro na direção da linha central dos elementos espirais. Uma redução das forças de atrito é o resultado, bem como uma diminuição do tempo necessário para trabalhar nos elementos espirais.
