Abstract

762,626. Hydraulic apparatus. WESTFALIA DINNENDAHL GROPPEL AKT. GES. June 28, 1954 [July 2, 1953], No. 18849/54. Class 69 (2). Overload protection means for a member such as a crushing jaw, a roll of a rolling mill, or a breaker shell of a cone crusher, comprises a cylinder 1 surrounded concentrically by an oil container 4 in communication by way of a pump 6 and a valve 8 with each end of the cylinder. A piston 2 in the cylinder has a rod 3 connected to the member to be supported. On the occurrence of an overload the piston is moved to the left and liquid is discharged through a relief valve 16 into the container 4. In a modification, the relief valve is dispensed with, and the left-hand end of the cylinder communicates with a bag accumulator so that when the excessive loading has ceased the piston is returned to its normal position.
