Abstract

"BOMBA DE DIAFRAGMA". Uma bomba de diafragma que supera o problema de falha de diafragma devido ao transbordamento da câmara de transferência de óleo e a inabilidade de auto-escorva. Um entalhe é fornecido na parte superior da superfície do cilindro de modo que o ar pode ser forçado de volta para o reservatório. Em adição, a mola de orientação conectada ao diafragma e suportada pelo pistão e feita rigida com uma constante de mola que produz uma pressão de orientação que pode superar as pressões de sucção anormais.
