GAS REGULATING AND SAFETY VALVE FOR BURNERS OF A MODULATABLE GAS HEATING DEVICE

摘要

The valve has a housing (1) with two controllable closing units, whose axes are spaced apart from one another and extend serially in a gas flow direction one behind the other between an inlet port (2) and an outlet port (4) of the housing. One of the closing units is driven from a spindle nut system that is coupled with an electric motor (15) with an excitation winding, and the other unit has a sealing body (10), which is connected with an anchor (9). The anchor is functionally arranged in a cylinder like hollow space, where the space is surrounded by the excitation winding of the motor.
