ABSTRACT:
A surge-pressure removing system for backpressure in an injection cylinder, wherein a surge-pressure absorbing cylinder is connected to an oil discharge pipe comnmunicated with the injection cylinder. A piston of this surge-pressure absorbing cylinder is located at a predetermined position by the gravity thereof or the like, and, when pressure in the oil discharge pipe is increased, the piston moves in accordance with the increased pressure to thereby prevent the surge-pressure from being generated. When the piston moves, air in the surge-pressure absorbing cylinder is discharged to atmosphere to thereby allow the piston to move more slowly.
