ABSTRACT:
An apparatus is provided for controlling flow of liquid through an aperture. The apparatus includes a housing and a float valve disposed in and unattached to the housing. The float valve is formed to include a float chamber and is movable in the housing between an aperture-blocking position and an aperture-unblocking position. The apparatus further includes a mechanism for controlling movement of the float valve by selectively venting fluid from the float chamber to reduce the buoyancy of the float valve.
