Title:
SOLENOID VALVE DRIVING CONTROL APPARATUS AND SOLENOID VALVE PROVIDED WITH SOLENOID VALVE DRIVING CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/061200
Kind Code:
A1
Abstract:
[Problem] To provide a solenoid valve driving control apparatus in which there is no possibility, despite the normal configuration of a magnetic path (in which a plunger is attracted by an attractor), that a determination of detachment will be erroneously made or that a plunger will enter a re-adsorption mode. [Solution] The present invention is configured such that, after power supply to a solenoid 66 is started at zero-cross timing by using a switch means 68 under control of a zero-cross timing generation means 72, when a value of a current flowing to a solenoid 66, detected by a current detection means 78, reaches a circuit protection current value Ic (αA), the stabilization mode is executed to repeat multiple times (4 times in total in embodiment illustrated in FIG. 4) an ON-OFF cycle of cutting off the power supply to the solenoid 66 by the switch means 68 (A5-A8 in FIG. 4).
