Abstract

Per la compensazione delle perdite della pressione di aspirazione è possibile disporre sulla pompa ad espulsori ovvero a pistoni una pompa di carico ovvero Booster (3) strutturato come pompa di flusso e può essere accoppiata propulsivamente con l'albero a gomiti (2) del manovellismo della pompa ad espulsori ovvero a pistoni tramite un innesto (2) magnetodinamico ovvero elettrodinamico, in modo tale che entrambe le pompe possano lavorare relativamente una verso l'altra con un rapporto del regime di giri stabile. In tal modo la parte idraulica della pompa di carico ovvero Booster (3) può essere ermeticamente isolata verso l'esterno.To compensate the losses of the suction pressure, it is possible to place on the ejector or piston pump a loading pump or Booster (3) structured as a flow pump and can be propulsively coupled with the crankshaft (2) of the crank mechanism of the ejector or piston pump through a magnetodynamic or electrodynamic clutch (2), so that both pumps can work relatively towards each other with a stable speed ratio. In this way the hydraulic part of the load pump or Booster (3) can be hermetically insulated towards the outside.
