ABSTRACT:
A hydraulic actuator package of the present invention comprises a variable displacement hydraulic motor for driving an inertia object with acceleration or deceleration, a speed sensor for detecting a speed of an output shaft of the hydraulic motor, a control valve for continuously varying the capacity of the hydraulic motor, which are integrally provided inside or outside a casing of the hydraulic motor, and an assembling body formed by integrally assembling an accumulator serving as a hydraulic source of the hydraulic motor and an airtight tank into a common pedestal, said assembling body being mounted on said casing, first and second ports of the hydraulic motor communicating with the accumulator and the airtight tank in the casing and the pedestal, and first and second external connection ports being defined in the pedestal or the casing, and capable of being connected to the first and second ports from the outside.
