A1
Abstract:
A servo regulator which moves a servo piston on the basis of operating fluid pressures in two pressure chambers is provided with: a sleeve which is inserted in an insertion hole formed in a case and which has a supply port capable of supplying the operating fluid, which is supplied from a fluid pressure source, to one of the pressure chambers; a spool valve which is disposed within the sleeve while being pressed by a pressing member; and a solenoid which is mounted to the case and which drives the spool valve through a plunger.
