| 摘要 |
<p>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 restri.sigma.tor (500) , wherein the manifold is provided with an inlet and an outlet (130A) , the inlet of the manifold being connected to the at least on e liquid storage tank; the delivery outlet flow restrictor is located downstre am 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.</p> |
