PROBLEM TO BE SOLVED: To provide a capacity control device for a hydraulic pump having simple and small construction and allowing the effective use of horse power output by a power source. SOLUTION: Two flow control mechanisms 11, 12 and a common horse power control mechanism 13 located therebetween are provided for a regulator 7 and feedback sleeves 11d, 12d of the flow control mechanisms 11, 12 are linked to servo pistons 3a, 4a in differential cylinders 3, 4 via feedback links 17, 18 and linked to a feedback sleeve 13d of the horse power control mechanism 13 via an intermediate link 19. Two flow control mechanisms 11, 12 are each arranged at an equal space from the horse power control mechanism 13 and a link mechanism consisting of links 17, 18, 19 is constructed so that the moving quantity of the feedback sleeve 13d of the horse power control mechanism 13 is set to be an average value for the moving quantity of the feedback sleeves 11d, 12d of the flow control mechanisms 11, 12. |
