PURPOSE: A hydraulic pump having a regulator which can be controlled outside is provided to control a secondary inflection point outside by applying eccentricity to a link shaft which is the position basis of an inner spring. CONSTITUTION: A hydraulic pump having a regulator which can be controlled outside comprises a regulator (110). The regulator generates hydraulic power by inhaling and discharging hydraulic fluid and comprises a body, a compen piston (111), a piston case (112), an outer spring (121), an inner spring (122), a spool (131), a sleeve (132), an adjust spring (141), an adjust screw (142), and a link shaft (161). The compen piston and the piston case convert discharge pressure into power. The outer and inner springs generate power which is proportional to the angle of a varied swash plate. The spool and the sleeve control the pressure of a large-diameter chamber to control the angle of the swash plate. The adjust spring and screw control a primary inflection point outside. |
