Abstract

Electronic controls for hydraulic valve regulate amount of oil acting on drive piston of ring rail. Pref, microswitch closes at first time rail reaches top of strokes & starts electronic counter which is adjustable for desired period of up & down motion. Switch closes 2nd time reattaining top of stroke, and control provides correction signal proportional to time error. This causes servomotor to adjust valve.
