Abstract

1. Pompa meccanica del carburante per motori a combustione interna.2.1. Pompe del combustibile del genere vengono azionate dal motore a combustione interna.In una nota pompa del carburante con membrana e pistone si deve ottenere che sia esclusa la presenza di bollicine di vapori e di aria nel combustibile alimentato al motore a combustione interna. Tuttavia questa pompa funziona solo con notevole oscillazioni della pressione.2.2. La nuova pompa del carburante presenta invece caratteristiche consistenti nel fatto che la pompa a pistone presenta da entrambi i lati di una parte a pistone (21) camere di lavoro (41, 42), che presentano un rapporto tra i volumi di alimentazione di circa 2 : 1, per il fatto che la camera di lavoro maggiore (41) alimenta attraverso una valvola di pressione (49) in una cavità (45), che è collegata direttamente con la minore camera di lavoro (42) e attraverso un'altra valvola di pressione (50) con un raccordo di pressione (48) che è un consumatore.1. Mechanical fuel pump for internal combustion engines. 2.1. Fuel pumps of this type are driven by the internal combustion engine.In a known fuel pump with membrane and piston it must be ensured that the presence of bubbles of vapor and air in the fuel supplied to the internal combustion engine is excluded. However, this pump only works with significant pressure fluctuations. 2.2. The new fuel pump, on the other hand, has characteristics consisting in the fact that the piston pump has on both sides of a piston part (21) working chambers (41, 42), which have a ratio between the supply volumes of about 2 : 1, due to the fact that the larger working chamber (41) feeds through a pressure valve (49) into a cavity (45), which is connected directly with the smaller working chamber (42) and through another valve of pressure (50) with a pressure fitting (48) which is a consumer.
