ABSTRACT:
Apparatus for controlling the level of a fluid in a reservoir. A reservoir has a trough within which is a valve means comprising a hollow cylindrical body having inlet and outlet apertures in fluid communication with a fluid source. A valve shuttle assembly slidingly connected to the valve comprises an "O" ring seal which defines a sealing region. The sealing region can occlude the fluid inlet aperture or permit fluid to pass to the outlet aperture. The valve shuttle is interconnected to a float which rises and lowers depending on the fluid level in the reservoir.
