Gas burner assembly for a gas hob, gas hob and gas oven

Abstract

A gas burner assembly for a gas hob includes a gas burner fed with gas via a gas line. Attached to the gas line is a gas control valve which is infinitely variably to control or shut off a gas volume flow to the gas burner, and downstream of the gas control valve a gas switching valve having a constantly open fluid duct and a closable fluid duct. The gas switching valve is selectively switchable between a first switching state in which the closable fluid duct is closed and a maximum gas volume flow to the gas burner is restricted by a cross-section of the constantly open fluid duct of the gas switching valve, and a second switching state in which the closable fluid duct is open and the maximum gas volume flow to the gas burner is restricted by a cross-section of a burner nozzle of the gas burner.
