<p><P>PROBLEM TO BE SOLVED: To realize simplifying of a hydraulic circuit for generating a control pressure, to realize stabilizing and generating of the control pressure and to realize size reducing of a control pressure valve. <P>SOLUTION: The pressure control valve includes a sleeve 62 in which an input port p1, an output port p2 and drain ports p4-p6 are formed, and a linear solenoid 11 for generating a thrust. The pressure control valve further includes a first spool which is arranged retractably in the sleeve 62, and in which a thrust is transmitted, the input pressure inputted to the input port p1 is pressure regulated and the output is outputted from the output port p2, and a second spool which is arranged retractably in the sleeve 62, the thrust is transmitted, the output pressure is selectively operated as a feedback pressure to the first spool. Since the output pressure is selectively operated as the feedback pressure at the first spool, a control valve, etc., becomes unnecessary. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
