Patent ID: 11473645

Abstract:
A shock-absorber has an outer cylindrical tube, an inner cylindrical tube, a rod, a main piston and a hydraulic stop member received in a compression chamber and operating during an end section of the compression stroke of the shock-absorber to cause an increase in the hydraulic damping force. The hydraulic stop member has a cup-shaped body mounted in the compression chamber and a first auxiliary piston which is mounted on a cylindrical body rigidly connected to the main piston and is configured to sealingly slide in the cup-shaped body during an end section of the compression stroke, encompassing a working chamber with the cup-shaped body. A sliding member is slidably received inside the cylindrical body for opening or closing at least one first passage of the cylindrical body through which oil flows from the working chamber of the cup-shaped body to the compression chamber of the shock-absorber.
