When P is reached, the l-th reaction body 31 moves to the first position, and the opening/closing valve 45 is opened and moved to the position #13=0ζ1, thereby allowing the χ fuel scum to pass through the inlet Ii! From i41 to communication passage 42C: Stream 1. Next, Pa 10 and Pana C are second-rate j Teya Fire. At this stage, the hysteresis valve 25 is closed by 1, so the pressure inside the pressure 817 rises rapidly, and the displacement of the trailing body 17 decreases within a short period of time from the activation of the electromagnetic pump 13. .
