Abstract

PURPOSE: To stop, hold and free float the load in an intermediate position, by forming a communicating hole equipped with a check valve and arranging a push rod coaxially on the spool in a three-position selector valve of spring closed center type.
CONSTITUTION: If a push rod 20 is pushed in against tension of a spring 19 under a state for a spool 12 to be held in its neutral position, the spool 12 is shifted against a holding spring 13 toward a push-in direction to allow a protrusion 21 of the push rod 20 to press open a check valve 18 against a spring 17. Then, the first cylinder port 9 is opened to a tank port 6, simultaneously with the second cylinder port 10 opened to the tank port 6, permitting the opening of both oil pressure chambers 7, 8 in a hydraulic cylinder 2 to a tank 3. Accordingly, because the fixing action of this hydraulic cylinder 2 is released, the load is subjected to a free float.
