<p>PROBLEM TO BE SOLVED: To suppress fluctuation in a direction of a gas fuel stream, and improve operativity, by interposing a baffle plate between a gas fuel inlet port and a gas fuel outlet port, so that gas fuel led to flow into by being passed through the inlet port is separated from the outlet port and directed to the center axial line of a gas fuel chamber. SOLUTION: When additional gas fuel is introduced to the inside of a chamber 22 when the inlet valve 33 of a pressure adjuster for gas fuel is opened, pressure applied to the lower surface of a diaphragm 18 is increased, so that the diaphragm 18 is upwardly displaced and the inlet valve 33 is energized on a closing side. Also, at this time, a coil spring 40 is compressed, and spring force applied to the diaphragm 18 is increased. Hereby, adjusted gas fuel pressure is retained in the chamber 22. In this case, a battle plate 30 comprising a circular arc-shaped upstanding wall 42 which partially surrounds the inlet port 23 and two side walls 44 extended divergently, is arranged between the inlet port 23 and the outlet port 17, so that pressure nonuniformity in different parts in the chamber 22 is suppressed.</p> |
