A regulator (10) includes a feedback lever (24) configured to move a compensating sleeve (32) in an axial direction of a compensating spool (30). The compensating spool (30) and the compensating sleeve (32) form: a self-pressure introduction chamber (34), into which a self-pressure Pd of a pump is introduced; and a pressure adjuster 51 configured to output a control pressure Pcl from the self-pressure introduction chamber (34) to a large-diameter pressure receiver (22) of a servo piston (21). The compensating sleeve (32) includes a stepped portion (42), to which a pressure in a direction in which a control spring (31) urges the compensating spool (30) is applied when the self-pressure Pd is introduced into the self-pressure introduction chamber (34). |
