摘要: A time-proportioning control system is disclosed for controlling an on-off solenoid valve of earth-working machine, the having a sensor responsive to external reference producing error signal, amplifier switch switching on and off in response signal capacitive feedback circuit connected from output input times dependent upon magnitude signal.
