  • Oil-injected compressor with a temperature switch
    Patent number: 8317484
    Abstract: An oil-injected compressor, with an oil circuit for lubrication, and an oil separating device which is used to separate the oil from the compressed air. A self-resetting temperature switch, which is used to switch off the compressor unit when the maximum temperature limit of the incoming compressed air is reached, is provided in the region of the inlet of the compressed air, which contains oil, in the oil separating device. At least one non-self-resetting additional temperature switch is provided in the internal area of the oil separating device, which immediately switches off the compressor unit following a fire or an explosion of the compressed air, which contains oil, and which is contained in the oil separating device.
