| 摘要 |
The present invention relates to an improved manifold ( 100 ) for use in a pumping system for pumping liquid, in particular but not exclusively liquid fuels. A liquid delivery system comprises at least one liquid storage tank ( 250 ); a manifold; an integral manifold vent system communicating directly with the manifold and comprising a manifold vent valve ( 140 ) and a manifold vent pipe ( 150 ); a first liquid sensor ( 110 ); and a delivery outlet flow restrictor ( 500 ), wherein the manifold is provided with an inlet and an outlet ( 130 A), the inlet of the manifold being connected to the at least one liquid storage tank; the delivery outlet flow restrictor is located downstream from the manifold; the first sensor is adapted to detect the formation of an air pocket in the manifold; and the integral manifold vent system comprises at least one section ( 155 ) having an internal diameter small enough to ensure smooth filling of the manifold with the liquid being dispensed when the manifold vent valve is opened to release trapped gas.
