<p>A hydraulic pressure generator comprising a body (10) in which is formed a principal bore (12), a piston assembly (14) slideably mounted in the bore (12) and defining with the principal bore a working chamber (26) connectable with a hydraulic actuator, the piston assembly (14) being selectively slideable in the principal bore (12) by means of an input rod (20), characterized in that the piston assembly (14) further comprises resiliently deformable means (54 ; 58) destined to deform when the pressure in the working chamber (26) reaches a predetermined value.</p> |
