Abstract

The high-performance hydraulic actuator comprises a cavity forming an expansion chamber (13) formed in the end of the rod (4) for joint expansion of the sliding walls (6, 14) of the cylinder (2) and of the said expansion chamber (13), and a set of non-stick grooves (16) and cavities (18) forming equilibrium chambers (17) formed in the sliding surface (10) of the rod (4), these means interacting for the purpose of maintaining a minimal operational clearance and of guiding the rod. <IMAGE>
