Abstract: A method for manufacturing a cylinder interior fuel injection valve and an apparatus for adjusting a fuel injection amount used therefor may sufficiently cope with a fluctuation in fuel pressure or combustion gas pressure that would occur in an actual engine. According to this manufacturing method, a position of an adjuster is adjusted (step 110), a fuel injection amount is measured (step 111), and it is judged whether or not the measured value of the fuel injection amount falls within a range of a rated value (step 112). Then, if the fuel injection amount is out of the range of the rated value, the process is returned back to the step 110, and if it falls within the range of the rated value, the process shifts to a subsequent step 113. Subsequently, a spring force of a valve closing spring is measured (step 113), and it is judged whether or not the measured value of the spring force falls within a control range (step 114). Then, if the spring force is out of the control range, the process is returned back to the step 110, and if it falls within the control range, the adjuster is fixed (step 115) and the process shifts to a next step.

Abstract: A proportional flow control valve in which a valve seat is provided in the proportional flow control valve body, a valve piece is slidably mounted on a movable iron core, and is urged toward the valve seat by an elastic member disposed between the valve piece and the movable iron core, and a holder is fixedly mounted on the movable iron core so as to limit the movement of the valve piece toward the valve seat caused by the elastic member. The proportional flow control valve is high in reliability in which the leakage of fluid is substantially zeroed even when fully closed, and the difficulties are eliminated that, when its flow rate adjusting means engages with or disengages from the valve seat, hammering sounds are produced and the flow characteristic is adversely affected, and which is simple in adjustment and is maintained correct in flow characteristic at all times.
