Bambi Bucket Service Manual

When the bucket is filled with water, the pressure pulls down on
the valve, riser and tripline until the upper end of the bullet
assembly engages the mechanical catch. The mechanical catch
is locked in place by the linkage arms.
To dump the valve, an electrical signal is sent to the solenoid
which pulls up on the linkage arms and unlocks the catch.
The weight of water in the bucket pulls down on the valve, riser
and tripline. The upper end of the bullet assembly pushes past
the spring-loaded catch and the tripline unwinds from the spring
reel allowing the dump valve to fully open.
When the electrical signal to the solenoid is removed, springs
return the linkage arms, solenoid, and catch to their original
positions.
When all of the water has left the bucket, the only downward
force remaining on the tripline is the weight of the valve and
riser. This weight is overcome by the spring reel which winds up
the tripline, riser and valve.
As the bullet assembly re-enters the head, it pushes past the
spring loaded catch. The tripline continues to retract into the
spring reel until the lower end of the bullet assembly reaches its
limit on the trip block. The head is now latched and ready for
another fill.
