A pneumatically actuated gas valve is positioned within the injet body. The pneumatically actuated gas valve is configured to adjust from a closed configuration to an open configuration in response to the flow of air through the air passage.

The present invention relates to a gas burner assembly (10), in particular for a gas cooking appliance, preferably for a domestic gas cooking hob. The present invention further relates to such a gas cooking appliance comprising at least one gas burner assembly (10). The gas burner assembly (10) comprises a burner head (12) including a plurality of high-power flame ports (32). The gas burner assembly (10) comprises at least one intermediate element (14, 16) including a plurality of low-power flame ports (38). The burner head (12) is arranged above the at least one intermediate element (14, 16). The high-power flame ports (32) are connected to a first gas inlet (30) via a horizontal Venturi pipe (22). The low-power flame ports (38) are connected to a second gas inlet (52) via an annular distribution chamber (46). The low-power flame ports (38) and the high-power flame ports (32) are located on different parts of the gas burner assembly (10) and arranged in super-imposed way. According to a first aspect of the invention, the gas burner assembly (10) comprises at least one base part (20) arranged beneath the at least one intermediate element (14, 16), wherein at least one low-power injector (18), at least one pre-mixing chamber (48) and preferably the second gas inlet (52) are integrated within said base part (20). According to a second aspect of the invention, the gas burner assembly (10) is arranged in the gas cooking appliance in that way that the primary fresh air for the high-power flame ports (32) is sucked from the bottom side and the primary fresh air for the low-power flame ports (38) is sucked from the top side of a work plate (54) of the gas cooking appliance.

A gas cavity burner, wherein the present invention discloses a burner applied to ovens, more specifically, the present invention discloses a tubular burner composed by two half-shells disposed superposed conforming an inner mixture and diffusion chamber the receives a comburent and a combustible in order to generate a pilot and primary flames, said two half-shells comprising substantially symmetrical perimetral surfaces wherein one said shell comprises a corrugated perimeter surface while the other comprises a flat perimeter surface, the burner of the present invention also presenting a spacer between both half-shells, in that said spacer reduces deformation issues caused by the heating, while it also brings more control to the pilot flame and aggregates a reduction of material thickness in the manufacturing of the burner.

A cooking appliance includes a cooking area. A hob can be located in the cooking area. The hob includes an injector holder base defining an air chamber and a burner interface chamber. An injector holder cover overlies the injector holder base. The injector holder base and the injector holder cover collectively define a venturi tube extending between the air chamber and the burner interface chamber. An injector is carried by at least one of the injector holder base or injector holder cover. A burner is supported on the injector holder cover.

A multi-crown gas burner with an injector holder module is attachable to a cooking hob and includes a flame-spreader module, positioned above the injector holder module, which includes a circular internal portion separated from an external annular portion by a substantially annular cavity. The injector holder module includes: at least one first venturi duct substantially horizontal to which at least one first injector faces, the at least one first venturi duct in fluid communication with a corresponding first chamber in fluid communication with a first set of doors provided in said external annular portion, so as to generate at least one first crown of main flames, a second substantially horizontal venturi duct to which a second injector, the second venturi duct is in fluid communication with a zone communicating fluidly with at least one passage provided in said circular internal portion for generating at least one simmering flame.
