Abstract
PURPOSE:To mechanically and properly control the closing motion of a movable valve element according to the variety in temperature by energizing the movable valve element for opening and closing the valve hole of a housing in the opening and closing direction by means of a solenoid energizing means and temperature sensing element energizing means. CONSTITUTION:A solenoid valve is provided with a housing 10 having a valve hole 11 and a movable valve element 20 for opening and closing the valve hole 11. A spring 30 for energizing the movable valve element 20 in the valve hole opening direction and a solenoid 40 for energizing the said element 20 in the same direction according to the variation in supplied electric current are arranged. In addition a coil spring 50 made of shape memory alloy for energizing the said element 20 in the closing direction according to the variation in temperature is provided. Balancing of each energizing force of the spring 30, solenoid 40 and coil spring 50 controls the opening and closing of the said element 20. At this time the coil spring 50 serves to decrease the rate of air flow in high temperatures and to increase it in low temperatures. In addition, the energization of the solenoid 40 serves to control the rate of air flow properly.
