Abstract

L'invenzione migliora la risposta di avviamento di una pompa a palette e riduce la perdita di potenza durante il fuzionamento ad alta velocità. Una pompa a paletta include un rotore formato con fessure, in cui sono disposte scorrevolmente palette. Per spostare le palette rispettive in attestatura contro un anello di camma una copia di piastre che ritengono il rotore e l'anello di camma frapposti tra esse sono formate con una pluralità di gole arcuate in cui è introdotto olio scaricato.Invece che prevedere una stretta gola formata nella medesima piastra di quella in cui sono formate le gole arcuate per fornire una comunicazione tra esse, una gola anulare è formata nella superficie laterale del rotore per sostituire la stretta gola o in aggiunta alla stretta gola, ed è strutturata in modo tale che essa è interrotta dalla paletta quando essa arretra mentre la gola anulare fornisce una comunicazione tra le gole arcuate quando la paletta viene spostata verso l'esterno.
