Abstract
A servo regulator includes a servo piston coupled with a swash plate, a pressure chamber provided to face an end portion of the servo piston, a spool configured to control a pressure in the pressure chamber by being moved by a solenoid, a biasing member configured to bias the spool against a thrust of the solenoid, and a feedback portion configured to change a biasing force of the biasing member in accordance with tilting of the swash plate, wherein the feedback portion is coupled with the swash plate via the servo piston.
