Claims

[Scope of utility model registration request]

In a spark ignition gas engine, which has a sub-chamber 30 in the cylinder head and a gas valve 10 for supplying auxiliary gas for ignition into the sub-chamber, the engine is ignited in the sub-chamber by a spark plug 40 to form a torch into the main fuel chamber. A gas valve for a spark ignition gas engine, in which an electromagnetic coil 5 is provided around the outer periphery of a gas valve 10 that supplies auxiliary gas for ignition to the auxiliary chamber to control opening and closing of a check valve 2.
