Valve insert and valve for gas appliances

摘要

The valve assembly for a gas burner appliance, with electrical ignition, allows a throttled gas flow through for ignition and then allow a full gas flow through the same channel as rapidly as possible. It has a valve spindle (8) operating with a valve closure (7) with play. The valve closure, as part of the main valve (15), acts as an auxiliary valve (14), controlled by the movements of the valve spindle. The auxiliary valve is held in the closed position by a spring (18), which also holds the valve closure in the open position.
