A separator (10) for separating a heavier liquid from a lighter liquid that floats on the heavier liquid is disclosed. Mixed liquids enter the separator through an inlet (18). There is an outlet (22) for the lighter liquid and an outlet (24) for the heavier liquid. There is also a float (28) which floats on the heavier liquid and sinks in the lighter liquid. A closure elements (52) shuts-off the outlet (24) until the float (28) is lifted by an accumulation of heavier liquid. A guide rod (46) is connected to the float so that it moves with it. A diaphragm (32) is subjected on one side to atmospheric pressure and on the other side to the pressure in the separator. The diaphragm, when the pressure in the separator is below atmospheric, hold the rod and float in a position in which the element (52) closes off the outlet (24). A backing plate (34) is provided against which the diaphragm (32) is pressed when the pressure in the separator is at or above atmospheric pressure. The backing plate (34) has an opening in it which exposes the diaphragm to atmospheric pressure. |
