Abstract:
A hydraulic actuator includes a piston accommodated to slide hermetically in a hollow cylinder to divide the internal volume of the hollow cylinder into two chambers. The hydraulic actuator includes a first movable element accommodated so that it can slide hermetically in a longitudinal cavity defined inside the piston stem to divide the longitudinal cavity into two portions with the first one connected to one of the two chambers and the second one connectable to a second circuit adapted to feed under pressure a second fluid into the second portion. The second fluid has a coefficient of compressibility and a nominal pressure greater than those of the first fluid to act as a shock absorber and/or damper in case of sudden peaks of pressure in the chamber connected to the first portion of the longitudinal cavity defined inside the piston stem.

Claim (Index 16):
A hydraulic actuator comprising a piston that is accommodated so that it can slide hermetically in a hollow cylinder so as to divide the internal volume of said hollow cylinder into two chambers mutually separated by the head of said piston, said two chambers being connectable separately, respectively by means of at least one delivery duct and at least one discharge duct, to a first circuit adapted to feed under pressure a first fluid into one of said two chambers with consequent emptying of the other of said two chambers for the extension or compression movement of said piston with respect to said hollow cylinder, comprising a first movable element that is accommodated so that it can slide hermetically in a longitudinal cavity defined inside the stem of said piston so as to divide said longitudinal cavity into two portions with the first of said two portions connected to one of said two chambers and with the second of said two portions connectable to a second circuit adapted to feed under pressure a second fluid into said second portion, said second fluid having a coefficient of compressibility and a nominal pressure greater than those of said first fluid so as to act as a shock absorber and/or damper in case of sudden peaks of pressure in said chamber connected to said first portion of said longitudinal cavity defined inside said stem of said piston.
