<p>PURPOSE:To ensure the adjustment between the measuring amount and the discharging amount, by performing the piston driving for discharge in the measurement of the high-pressure liquid by means of the pressure of the fluid. CONSTITUTION:The pressurizing liquid supplied through supply opening 18 is filled into filling room 37 between end wall 8 and head part 12 of piston 9 from conduction hole 15 at center part 10 of piston 9 and through nonthickness part 31. In this case, no pressurizing liquid flows into filling room 38, and piston 9 is pressed to the left side of the figure to reach up to fringe forming component 16'. The pressure air is supplied through inlet 34 at the time point when room 37 is filled up, and driving piston 33 is shifted toward arrow (b) against the elasticity of spring 35. At this position, the liquid flows into room 38, and room 37 is linked to vacant room 23 through part 31 to be connected to discharge opening 24 linking to the air. Then the liquid pressure functions to the top surface of head part 11 at the side of room 38, and piston 9 slides gradually toward the right to discharge the liquid within room 37. The right sliding of piston 9 is continued until part 12 of piston 9 touches fringe forming component 8'.</p> |
