Abstract: A gas burner for a gas cooktop has a gas burner body with gas outlet openings. A thermogenerator is arranged above the gas burner body, advantageously arranged concentrically relative to said gas burner body and with the same shape and size, wherein the thermogenerator is heated by said gas burner body. The thermogenerator bears against a cooler pot base by way of its upper face. The thermogenerator generates electrical energy which is used to operate a control of the gas cooktop and which can be stored.

Abstract: The invention relates to a valve arrangement for a gas installation comprising a valve body with at least one gas inlet, whereby at least one gas outlet is assigned to a gas inlet and, more particularly whereby one gas outlet can be closed by means of a medium-controlled or flame-controlled safety valve element, whereby one gas outlet be reduced in cross-section and/or closed by means of a valve element arranged on a non-rotating shaft, whereby the actuator (6) of the valve element (10) is in the form of a linear motor (6) on the shaft of which the valve element (10) is directly arranged.
