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 closed position blocks a fluid connection between the pressure chamber and a pressure equalization area exterior of the pressure relief valve. The pressure relief piston includes at least one piston pressure surface delimiting the pressure chamber in the closed position transversely to the actuating direction of the piston, wherein in the closed position of the pressure relief piston a projection of the at least one piston pressure surface in a projection plane transverse to the actuating direction of the pressure relief piston delimits only a part of the pressure chamber transverse to the actuating direction of the pressure relief piston.
