<p>A control valve associating device (31) has a plurality of control valves (80 to 85) which includes a pair of logic valves (40, 41) supplying and controlling hydraulic pressure to a hydraulic actuator, thereby simplifying the piping between the logic valves. This device has a housing (310), a pair of oil passages (34a, 34b) aligned parallel to each other in such a manner that the valves (40, 41) forming control valves are disposed in the housing so as to be substantially perpendicular to the oil passages (34a, 34b), wherein pump ports (43a, 43b) of the logic valves communicate with the corresponding passages (34a, 34b), and work ports (45a, 45b) for the logic valves are provided substantially perpendicular to the passage direction and orientation direction of the logic valves.</p> |
