Abstract

"BOMBA HIDRáULICA E GRUPO DE ELETROBOMBA". A invenção se refere a uma bomba hidráulica, notadamente de grupo eletrobomba. Essa bomba é do tipo que compreende um corpo de bomba (6) que contém uma bomba com engrenagem e equipado com uma abertura de aspiração de um líquido de baixa pressão e uma câmara (21) de refluxo de líquido de alta pressão, que se comunica com um canal de saída de alta pressão (46) ligado a um circuito hidráulico utilizador, e uma capacidade hidráulica (35) de amortecimento das pulsações produzidas pela bomba e equipada com meios de desaeração para evacuar o ar suscetível de estar preso lá. A bomba é caracterizada pelo fato de que os meios de aeração são formados pelo líquido de alta pressão refluído pela bomba (1) no canal de saída 45, 46. A invenção é utilizável para grupos eletrobomba.
