Abstract

A hydraulic actuator system includes a hydraulic actuator having a housing (104) with a piston (102) having a piston shaft (103) arranged within the housing. The housing is formed to have first, second and third regions (R1, R2, R3), wherein the first region is between the second and third regions and has a larger major dimension than the second and third regions. The system also includes first, second, and third piston heads (202, 204, 206) connected to the piston shaft with the first piston head being tween the second and third piston, wherein the first position head is within the first region and divides the first region into two volumes, the second piston head is in the second region and defines a first volume and the third piston head is in the third region and defines a fourth volume. The system also includes a mode selection device (106) operably connected to the first, second, third and fourth volume.
