Abstract
PURPOSE: To shorten a sliding amount of a change-over spool and improve an operability thereof by a method wherein a select valve switched by a pilot pressure to switch a change-over valve is provided between a load port in the change-over valve and a spring chamber in a pressure compensating valve.
CONSTITUTION: A select valve 2, switched by a pilot pressure to switch a pilot operating change-over valve 1 to communicate load ports A, B with a spring chamber 36 selectively, is provided between the load ports A, B in the pilot operating change-over valve 1 and the spring chamber 36 in a pressure compensating valve 3. When an electromagnet 16A or the same 16B is excited, a spool 12A for a pressure reducing valve or the same 12B controls a pressure in a fluid chamber 8A or the same 8B to slide a switching spool 6. Consequently, it switches a spool 20 for the select valve 2 and communicates the load port A or the same B with the spring chamber 36 in the pressure compensating valve 3 to control an amount of flow to the load port A or the same B into a constant amount. Thereby, a sliding amount of the switching spool 6 may be shortened and an operability thereof may be improved.
