<p>PROBLEM TO BE SOLVED: To provide a regulator for a variable capacity pump in which a stable horse power can be controlled even if a certain change occurs in a horse power control characteristic due to use over time.SOLUTION: A regulator 10 is provided with a feed-back lever 24 for moving a compensation sleeve 32 in an axial direction of a compensation spool 30. The compensation spool 30 has a self-pressure feeding chamber 34 for feeding a self-pressure Pd of a pump, and a pressure adjustment land part 33 communicating with the self-pressure feeding chamber 34 to feed a control pressure Pcl to a large diameter pressure acceptance part 22 of a servo-piston 21 through the compensation sleeve 32. The compensation sleeve 32 has a control pressure output chamber 36 for adjusting the control pressure Pcl with the pressure adjustment land part 33 of the compensation spool 30 and a step part 42 of the compensation sleeve 32 on which a reaction force of the self-pressure Pd fed into the self-pressure feeding chamber 34 of the compensation spool 30 acts.</p> |
