<P>PROBLEM TO BE SOLVED: To provide a device for controlling the operation of connecting two units (13, 17), on which a pressure medium can be made to act, with one pressure medium source (18) while staggering the time for the connection. <P>SOLUTION: In the device, a simple and compact structure is realized and large motive power is also obtained as follows. That is to say, there is provided a common main control valve (21) including a main valve slider (26) which follows a servo-valve slider (33). In this case, the servo-valve slider (33) can slide in cooperation with pressure chambers (44, 45) on which the pressure medium, preferably, the pressure medium waiting at an inlet (22) of the main control valve (21) can act. The pressure chambers are located on opposite sides to each other. Also, in this case, the pressure action of the pressure chambers (44, 45) can be controlled by a pilot control valve (43) in accordance with a signal which can be supplied from the valve. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
