IMPROVED COOKING GAS BURNER.

摘要

The present invention provides a cooking gas burner assembly including a distributor(30), a gas manifold (50) and a cup (40), said cup (40) being located between saidgas manifold (50) and said distributor (30). The invention also provides a methodof assembling a distributor (30) and a cup (40) in a cooking gas burner assembly,said method including the steps of providing: said distributor (30) with downwardlyextending spigots (32), providing said cup (40) with recesses (48) to receivesaid spigots (32), said recesses (48) including a base surface (246), said recesses(48) being sized and or shaped whereby thermal expansion of said distributor(30) results in substantially no increase in the contact surface between saidcup (40) and distributor (30), when said distributor (30) is hot compared to whenit is cold.. The invention further provides a burner assembly having at leasta cap (220) and a distributor (30) on which said cap (220) is mounted, said distributor(30) including an internal and an external crown of flame ports, and at least onecross lighting passage (37) there between, said cap (220) including an aperture(222) there through which is adapted to be positioned over said cross lightingpassage (37)when said cap (220) and distributor (30) are assembled. The inventionfinally provides a cooking gas burner assembly having a distributor (30) anda first formation to support said distributor (30) in said assembly, said distributor(30) and said first formation including spigots (32) and recesses (48) to allowsaid first formation to support said distributor (30), said recesses (48) includinga surface being sized and or shaped whereby thermal expansion of said distributor(30) results in substantially no increase in the contact surface area betweensaid first formation and distributor (30), when said distributor (30) is hotcompared to when it is cold.
