Abstract
PURPOSE: To make a valve compact, by changing the duty ratio of positive and negative electrical currents to perform proportional control over the degree of opening of the valve which is for opening or closing a communication hole on a hollow iron core by a moving-coil linear motor provided around the hollow iron core.
CONSTITUTION: In a valve unit 10, a slide valve 23 integrated with a bobbin 17 is displaced in response to the magnitude of electrical current to a solenoid 18 to control the area of opening of a communication hole 22. When the output of a valve drive circuit is a constant negative DC voltage, the slide valve 23 is displaced leftward for entire closure. To control the degree of opening of the valve to 75%, the output of the valve drive circuit is first skipped to a duty ratio of 50% and changed to a duty ratio of 75% and the solenoid 18 is energized to put the degree of opening of the valve at 75%. The degree of opening is then maintained at 75% by the drive circuit output of 50% in duty ratio. For other degree of opening of the valve 23, similar operation is effected.
