Abstract

Apparecchio come disposto interno ad un compressore a vite di refrigerazione che, alla destra del compressore, interrompe il flusso di olio iniettato nella camera di lavoro del compressore e l'olio che viene diretto ai cuscinetti di rotore del compressore e che, all'avvio del compressore, apre il flusso dell'olio a quelle ubicazioni mediante l'uso di condizioni interne ambiente del compressore che esistono inerentemente in quei tempi rispettivi. Il funzionamento dell'apparecchio è pertanto "fail safe" ("esente da guasti") e viene eliminata la necessità di un sistema valvolare esterno di interruzione del flusso dell'olio e la necessità di eseguire il monitoraggio e/o di provare il flusso dell'olio nell'interno del compressore.
