摘要： A blower assembly (105) for supplying a combustible mixture to a burner of a gas -fired appliance, the blower assembly (105) including a housing (145) defining an interior space, an impeller, a motor (155) operatively interconnected with the impeller to drive the impeller, an elongated blower conduit, a single-piece venturi (165), a gas supply space, and a gas supply port (211). The single-piece venturi includes a converging portion (210) having a wide end (220) and a narrow end, a diverging portion (215) integrally formed with the converging portion (210) and having a wide end (240) and a narrow end, and multiple entrainment openings (250) in the diverging portion (215) proximate the narrow end of the diverging portion (215). The flow of combustion air over the entrainment openings (250) draws gaseous fuel through the entrainment openings (250) from the gas supply space. Gaseous fuel is entrained in the flow of combustion air and mixed with the combustion air in the diverging portion (215) to create the combustible mixture.
