发明名称 Electromagnetic pilot type selector valve
摘要 An electromagnetic pilot type selector valve which can serve as a double-solenoid type selector valve or a single-solenoid type selector valve by merely increasing or decreasing the number of solenoid mechanisms and by providing a few component parts. This selector valve includes large and small pistons having different pressure receiving areas for driving a main valve disc. When two solenoid mechanisms are mounted, the main valve disc is switched over by pilot fluid pressure alternately applied on the two pistons. When one solenoid mechanism is mounted, the main valve disc is switched over by switching pilot fluid pressure applied on the large size piston, while the main valve disc is constantly pushed in one direction by pilot fluid pressure applied on the small size piston.
