<p>PROBLEM TO BE SOLVED: To proportionally control the flow of a hydraulic fluid flowing into or out of a pair of cylinder chambers by arranging a first linear actuator in a first bore hole, and arranging a second linear actuator in a second bore hole. SOLUTION: A control valve assembly 10 is constituted of a valve main body 12, a first bore hole 13 and a second bore hole 14 are bored through the valve main body 12, a first reciprocation control spool 16 is provided in the first bore hole 13, and a second reciprocation control spool 18 is provided in the second bore hole 14. The first and second reciprocation control spools 16, 18 are connected to a first linear actuator 54 generating the movement of the first reciprocation control spool 16 in the first bore hole 13 fitted to one side of the valve main body 12 or a second linear actuator 56 generating the movement of the second reciprocation control spool 18 in the second bore hole 14. The flow of a hydraulic fluid flowing into or out of a pair of cylinder chambers can be proportionally controlled.</p> |
