ABSTRACT:
The specification discloses an automatic programmable valve sequencer employing a rotatable cam cylinder operating adjacent cam valves by means of cam segments mounted thereon to directly operate air cylinders or other air-operated tools.
While the cam cylinder is manually advanced between steps where such cylinders or other tools are to be actuated, if a particular program doesn't utilize all the steps available, by virtue of one cam cylinder in combination with several control valves being able to automatically advance the cam cylinder when programmed to do so, the valve programmer will advance past vacant steps to the start of the next programmed cycle immediately on completion of the previous one.
