A valve member 26 and a valve seat member 31 are disposed in the valve storage chamber 25, and an adjusting screw member 41 provided with an outflow port 42 is installed to the valve seat supporting hole 23. The adjusting screw member 41 has a first male screw 43 screw-united with the valve seat supporting hole 23, and a second male screw 44 screw-united with the valve seat member 31. Both male screws 43 and 44 have different pitches, and are adjusted in their valve openings by the adjusting screw member 41.SELECTED DRAWING: Figure 3 |
