    • A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners employs an excess fuel containment compartment (24) which receives any excess fuel which might be fed to the fuel supply chamber (40) . The excess fuel causes a receptacle (20) in the compartment to move downwardly. Through a rod (30) and balance arm (18), such movement communicates with an automatic wick extinguisher (42) to extinguish the wick flame immediately in response to the excess fuel condition. Also the mechanism prevents re-ignition of the wick (54) until the danger of flareup is removed. This safety device also alerts the user of the liquid fuel burner to dangerous conditions by a mechanism comprising a highly visible warning gauge needle (34) . In addition, this safety device can be easily reset if accidentally triggered when overflow conditions do not exist, and the burner can be readily serviced and restored to operation should an excess fuel malfunction occur.
    • 用于防止引燃液体燃料燃烧器中不受控制燃烧的安全装置采用多余的燃料容纳室(24),其容纳可能被供给到燃料供应室(40)的任何多余的燃料。 多余的燃料导致隔室中的容器(20)向下运动。 通过杆(30)和平衡臂(18),这样的运动与自动吸油枪(42)连通,以响应于过量的燃料状况立即熄灭油烟。 此外,该机构防止芯(54)的再点火,直到除去火花的危险。 该安全装置还通过包括高度可见的警示计针(34)的机构向使用者警告液体燃料燃烧器的危险状况。 另外,如果在不存在溢流条件的情况下意外触发,则该安全装置可以容易地复位,并且如果发生过多的燃料故障,则燃烧器可以容易地维修并恢复运行。
