Abstract

PURPOSE: To prevent obstruction to supply of a fluid and prevent hunting by a method wherein two slidable valves are arranged in outwardly energized condition by spring, in a slidable valve member.
CONSTITUTION: With pressurized fluid of the same pressure fed from input ports A and B, a valve member 11 receives the same pressure from opposite sides and stops at a neutral position, to interrupt the communication between an output port C and the input ports A, B. Due to the pressure of the fluid from the port A, however, a valve 12 moves rightward as against the energized force of a spring 14 and the pressure of a pressurized fluid in a spring chamber d, and parts from a contact portion of a stop ring 15, to open an inlet port 11a into an outlet port 11c. On the other hand, due to the pressure of the fluid from the port B, a valve 13 moves leftward as against the force of the spring 14 and the pressure of the pressurized fluid in the spring chamber d, and parts from a contact point of a stop ring 16, to open an inlet port 11b into the outlet port 11c.
