<p>PURPOSE: To suppress a leakage rate of solenoid pressure from a gap between a spool and a valve hole in a pressure regulating valve which increases an output pressure from an output port higher as a solenoid pressure is increased without necessitating elongating a valve length and varying spool material. CONSTITUTION: A stepped portion (j) to which output feedback pressure is applied is formed on a spool (h). An output feedback pressure port (e) is arranged between a solenoid pressure port (f) and a drain port (d).</p> |
