Dump Valve Operation
The Bambi Bucket uses a tubular fabric valve to control the
flow of water exiting the bucket. The lower end of the tube
has a flange which is attached to a circular opening in the
bottom of the bucket.
The upper opening of the tube is flattened and has a series of
grommets and purse strings laced alternately from each side.
The lower end of each string terminates in a washer and a
knot. Each string passes through a grommet in one side of the
tube, crosses the opening, and passes through a corresponding
grommet on the other side of the tube.
The upper ends of the purse strings are attached to a metal
ring. This ring is also attached to the riser cable.
When the riser cable is pulled upwards, it pulls the ring and
puts tension on the purse strings. This draws together the top
faces of the tube and a rubber layer below the grommets seals
the upper end of the tube.
When the bucket is dipped and filled with water, the water
pressure in the bucket presses on the outside of the tube and
reinforces the seal.
To open the valve, the tension on the riser cable is released,
allowing the riser, purse strings and valve tube to move
downwards due to the weight of the water in the bucket.
The valve tube turns inside out and extends below the bottom
of the bucket. The flattened end of the tube returns to a
circular shape allowing all the water to exit the bucket.
When all the water has exited the bucket, the riser cable pulls
the valve tube back to its starting position.
