Abstract
A hydraulic actuator for a hydraulic actuation system of an aircraft includes a housing defining a cavity, a piston dividing the cavity into extension and retraction chambers and movable relative to the housing to increase volume of one chamber and decrease volume of another of the chambers. A bypass includes first and second bypass ports and a connecting bypass line, and first and second chamber ports opening into the extension and retraction chambers at all positions of the piston relative to the housing for passage of hydraulic fluid. The first and second bypass ports open into one of the extension chamber and retraction chamber when the piston is at a first position relative to the housing so the first bypass port and the second bypass port open into respective ones of the extension chamber and the retraction chamber when the piston is at a second position relative to the housing.
