Solenoid valve control apparatus
摘要:
A solenoid valve control apparatus has a solenoid valve having first and second solenoid valves that output first and second solenoid pressures respectively, a pressure regulation valve that works with the first and second solenoid pressures being working signal pressures, and a foreign matter removal controller that removes a foreign matter that adheres to a valve open/close portion of the solenoid valve. Each of the first and second solenoid valves has a solenoid coil that drives a plunger inside the solenoid valve in accordance with an application current. The foreign matter removal controller is configured so that when applying the rectangular-wave current, which performs a reciprocating movement of the plunger and removes the foreign matter, to the solenoid coil of one solenoid valve of the first and second solenoid valves, a current application to the solenoid coil of the other solenoid valve, by which the solenoid pressure becomes a maximum pressure range, is maintained.
