PURPOSE:To attain the rational piping and to prevent the leakage of gas, etc. of the piping system including a governor, by providing all pressure control mechanisms to a forming body for a primary gaseous pressure room. CONSTITUTION:A gas burner 1 contains a forming body 2 for a primary gaseous pressure room made of die casting aluminum and having an approximately square plane. A gas inflow port 3 is provided at an end face of the body 2. The primary gaseous pressure room 4 is formed contiguously to the port 3, and a diaphragm valve 5 and a hemispherical valve 6 interlocking the diaphragm valve 5 are provided within the room 4. Thus the flown-in gas goes into a secondary gaseous pressure room 9 of a forming body 8 for a secondary gaseous pressure room through a gap formed between the valve 6 and a valve seat 7. A gas outflow port 16 is provided to the body 8. |
