Abstract

"ASPIRADOR A VáCUO". Um aspirador a vácuo possui um motor elétrico que aciona um impelidor de ar (74) para criar sucção e uma bomba (120) a qual esgota material líquido através de um tubo de entrada (310) do fundo de um tanque (32) e o expele do tanque. O aspirador a vácuo também inclui um dispositivo mecânico de bloqueio e cancelamento que desliga automaticamente o motor se o nível de líquido no tanque se tornar muito alto. O usuário pode, todavia, cancelar este desligamento automático com o objetivo de continuar bombeando líquido para fora do tanque. Um dispositivo de escorva está localizado no tanque comunicado hidraulicamente com a bomba, e a válvula (58) é atuada de forma seletiva para estabelecer um diferencial de pressão hidráulica no dispositivo de escorva para, desta forma, escorvar a bomba (120).
