Hydraulic actuator equipped with an end-of travel slowing device

A hydraulic actuator comprising:

• a cylinder in which a piston secured to a rod is mounted so as to slide in a sealed manner in order to delimit in the cylinder a hydraulic extension chamber and a hydraulic retraction chamber that are connected to respective extension and retraction ports, the hydraulic actuator comprising slowing means for slowing the piston when the piston approaches a retracted position,
• wherein the slowing means comprise first and second hydraulic passages connecting the extension port and the extension chamber, the first hydraulic passage comprising a seat while the piston bears a retractable finger having an end that comes to bear against the seat in order to close the first hydraulic passage when the piston approaches the retracted position, such that only the second hydraulic passage remains open while the piston completes its travel towards the retracted position, and
• wherein the seat is preceded by an internal shape of a ferrule intended to cooperate with the end of the retractable finger before the retractable finger comes to bear against the seat in order to gradually reduce a flow cross section of the first hydraulic passage.
