The valve (12) includes a chamber defined by an upper portion (15) and a lower portion (17). The floating element (14) is adapted to be displaced between an inoperative configuration in which the floating element is located in the upper portion (15) and an operative configuration in which the floating element engages an egress means (26) to block egress of liquid through said chamber. The ejector means (18) can disengage the floating element (14) from the egress means (26) manually to reset the control device (50).</p> |
