Abstract

Viene descritto un dispositivo di pompaggio con uno stadio pompante principale realizzato sottoforma di pompa ad alta pressione con una pompa di prevalenza associata, la cui quantità di mezzo di flusso in eccesso viene scaricata verso il serbatoio tramite un cammino di flusso di scarico. Per innalzare la potenzialità del dispositivo di pompaggio con un minimo di impegno tecnico del dispositivo del circuito secondo l'invenzione, le zone dello stadio pompante principale sottoposte ad un carico termico e/o meccanico elevato vengono comprese nel cammino di flusso di scarico, in modo tale per cui la quantità di mezzo di flusso in eccesso viene scaricata e raggiunge queste regioni potendole efficacemente raffreddare.
