  • Feed pump
    Patent number: 6152687
    Abstract: In a feed pump designed for feeding fuel in a motor vehicle and having two feed chambers (11, 12) located opposite one another, of which one is connected to an inlet port (18) and the other to an outlet port (19), the feed chamber (11) connected to the inlet port (18) has a calming region (21) which a compression region (22) adjoins. Fuel entering the feed pump is thereby first calmed. Subsequently, in particular, gas bubbles present in hot fuel are dissolved due to the vapour pressure in the fuel being exceeded.
