ABSTRACT:
A novel valve, including a restoring spring which is pressed into a spring chamber opening and is held in the spring chamber opening by a radially oriented tension on one end of the spring; the depth to which the restoring spring is pressed determines the magnitude of the spring force acting upon the valve closing part. By dispensing with an adjusting sheath, not only is the danger of chip formation in the press-fitting operation lessened, but the production cost of the valve is reduced substantially as well. The valve is used as a fuel injection valve for fuel injection systems.
