Abstract
A crusher includes first and second crusher bodies defining a crushing gap. A hydraulic cylinder is coupled to one of the crusher bodies to adjust a width of the crushing gap. A pressure relief valve includes a pressure chamber communicated with the hydraulic cylinder. A pressure relief piston is movable between a closed position and an open position. The pressure relief piston includes at least one piston pressure surface delimiting the pressure chamber in the closed position transversely to the actuation direction of the piston, the pressure relief piston including a surface area at an end facing away from the pressure chamber, which surface area delimits the chamber area transverse to the actuating direction of the piston to transfer a closing force to the pressure relief piston in a closing direction of the closed position when pressure is applied in a chamber area.
