ABSTRACT:
A backflushing system capable of being used with an automatic milking device is the subject of this patent application. The system includes a control cam (54) which can be moved linearly to effectuate the various functions. The cam (54) has formed thereon a plurality of lands (64, 66, 68, 70) which operate various actuators (92, 94, 96). The various flushing functions and operation of a fail-safe valve (30) are governed by the actuators (92, 94, 96). In a preferred embodiment, the cam (54) is movable in both forward and reverse directions and is so controlled by a toggle switch (72), movable between two positions, which operates a two position, five way regulation valve (58).
