Abstract: An injet for a gas burner includes a first gas orifice and a second gas orifice. An injet body defines an air passage and a gas passage. The first and second gas orifices are mounted to the injet body. A pneumatically actuated gas valve blocks a flow of gaseous fuel through the gas passage to the second gas orifice in a closed configuration. The pneumatically actuated gas valve is configured to adjust from the closed configuration to an open configuration in response to a flow of air through the air passage. A flow restriction body is disposed upstream of the pneumatically actuated gas valve. The flow restriction body defines a through hole via which air is flowable to pneumatically actuated gas valve.

Abstract: A gas burner assembly for a cooktop appliance includes a flame ring comprising a plurality of flame ports arranged in an annular array. An outer ring and an inner ring collectively define each flame port of the plurality of flame ports. The outer ring and the inner ring are concentrically aligned and concentrically mated. As a result of this arrangement of the outer ring and the inner ring, the plurality of flame ports are defined by the outer ring and the inner ring. The plurality of flame ports extend radially between the inner ring and the outer ring.
