Abstract

PURPOSE: To obtain a small position control valve of a simple construction requiring no adjustment by a method wherein a passage of an operation oil is controlled with opening or closing a through hole provided on a slide portion by moving a sliding body fitted onto the outside circumference of the slide portion.
CONSTITUTION: A slide portion 15 having a load check valve 16 which opens or closes a pump port 6 and a cylinder port 7 is inserted into a valve body 1 and in the slide portion 15 are provided a through hole 18 and, a tank port 22 and a through hole 23 which are opened and closed by an unload valve 20 and a sliding body 26. The sliding body 26 forms a width L2 smaller than a distance L1 between a through hole 23 end and a stopper 27 to control a neutral band range. And with the sliding body 26 placed in the position as shown in the figure, an operation oil passage is controlled to a pump 10/the tank port 22, the pump 10/a cylinder 12, or the cylinder 12 and the pump 10/the through hole 23 by opening the through hole 23 by the difference of L1-L2, moving the sliding body 26 to the left to close the through hole 23 or moving it to the right together with the stopper 27. This method provides a small position control valve of a simple construction reguiring no adjustment for the neutral band range.
