てある制御バルブ構造。 A push-pull spool 23A is installed inside the valve case 30, and an inner small-diameter stopper mechanism 33 and an outer small-diameter stopper mechanism 31 are integrated with the push-pull spool 23A.
In addition, an inner large-diameter stopper mechanism 34 and an outer large-diameter stopper mechanism 32 are integrally provided in the valve case 30, with one end of the compression spring 29 serving as both inner stopper mechanisms 33 and 34, and the other end serving as both outer stopper mechanisms. 31 and 32 are in contact with each other to set the compression spring 29 to an initial compression state, and the control valve structure is configured to bias the push/pull spool 23A to a neutral state, A control valve structure in which the stopper mechanism 33 and the inner large-diameter stopper mechanism 34 are also served by stepped portions of the outer peripheral surface of the push/pull spool 23A and the inner peripheral surface 30A of the valve case 30, respectively.
