A separator (10) for separating a heavier liquid from a lighter liquid which is intended to operate between a fuel tank (12) and a fuel pump connected to the fuel outlet (24) of the separator (10) includes a float (30) which is light enough to float on the heavier liquid and which is heavy enough to sink in the lighter liquid. The float controls opening and closing of a valve (44, 46) through which heavier liquid is disclosed from the separator. As heavier liquid accumulates, the float lifts to open the valve (44, 46). A plate (34) subjected to a force caused by fuel flowing into the separator through the inlet (16) prevents the float opening the valve whilst the separator is in sub-atmospheric pressure. The plate can be replaced by a diaphragm which is subject on one side to atmospheric pressure and on the other side to the pressure in the separator. <IMAGE> |
