Improved hydraulic cylinder for a work vehicle

Abstract

A hydraulic cylinder for operating a work element of a work vehicle includes—a housing defining an inner volume and a piston slidably movable inside the housing in tight manner so as to divide the volume into two fluidly separated portions. The piston is connected by a rod to the work element. The housing defines two openings respectively connected to the two fluidly separated portions for allowing the passage of a fluid in pressure so as to move accordingly the piston. The hydraulic cylinder also includes a cushioning device configured to dampen the movement of piston inside the volume when it receives a sudden movement coming from the work element through the rod. The hydraulic cylinder also includes stroke variation means configured to vary the positioning of cushioning device inside the volume so as to vary a dampened stroke of piston.
