Abstract
PURPOSE:To adjust a shock abatement effect at the time of off-operation in an original manner by installing an oscillator outputting a reference signal, both first and second time constant circuits, a first comparator, and a second comparator pulse-driving a power switching element. CONSTITUTION:In this valve, there are provided with a first time constant circuit 7 generating ramp, signal in accordance with a first time constant when an input signal voltage is turned on and a second time constant circuit 13 performing voltage discharge in accordance with a second time constant. Both circuits give output to an input end at one side of a second comparator 5. In order to do operation like this, such a signal that causes to generate a time constant signal of the second time constant circuit 13 is taken in from output of the first time constant circuit 7, and it is compared with the reference voltage, whereby a first comparator 15 is turned on or off, through which charging and discharging operations of the second time constant circuit 13 are selected.
