Patent number: 10240785Abstract: A solenoid valve driving apparatus includes switching means for ON/OFF-controlling application of a direct current voltage to a solenoid of a solenoid valve, and signal outputting means. A first period and a consecutive second period are set as a valve opening operation period of the solenoid valve. When the signal outputting means outputs the PWM signal to the switching means, a duty ratio of the output signal is set to be higher in the second period than in the first period so that a power supplied to the solenoid is larger in the second period than in the first period. As a result, a valve opening operation is performed in the solenoid valve reliably, and loud noise generation during the valve opening operation is suppressed.Type: GrantFiled: January 27, 2011Date of Patent: March 26, 2019Assignee: Noritz CorporationInventors: Daisuke Konishi, Akira Ohta, Yoshihisa Kitano, Tomoya Nakano, Yoshifumi Atobe, Haruki Inoue, Yoshitaka Kimura, Ryo Ikeda, Tomoki Kishimoto, Yasuhide Ikeuchi, Tomoko Ikeuchi
