Abstract

A hydraulic actuator includes a piston housing having a head end and a base end opposite the head end and a drive piston movable between a first piston position proximate to the head end and a second piston position proximate to the base end. The hydraulic actuator further includes a control valve positionable between a first control valve position, in which the control valve directs fluid into the base end, and a second control valve position, in which the control valve directs fluid into the head end. A pressure-based position feedback system configured to facilitate transition of the control valve between the first control valve position and the second control valve position in response to predetermined head end and base end pressures.
